Thunders Cloud

Data files per test case, reordering test cases in a test set, and mobile tests accessibility scans

TL;DR

Attach a data file to every test case and run dozens of data-driven scenarios together in a single execution. Reorder the test cases inside a test set to control what runs first, run accessibility scans on mobile tests the same way you already do on web. We also shipped a batch of smaller test-run, test-case, and reliability fixes.

FEATURE

Data file per test case: associate a data file with a test case and it runs once per row automatically, no manual iteration setup needed. CI pipelines can now opt into this per-test-case data-file mode too.
Mobile tests accessibility scans: the accessibility persona can now execute accessibility tests on iOS and Android apps, with native findings normalized into the same report you already get on web, including richer alt-text findings.
See when and why your new app's URL isn't reachable: when you add a new app and its URL returns an HTTP error, Thunders now detects it and tells you what's wrong, the same way it already does for DNS, TLS, and firewall issues, with a suggested fix.
Set execution order for test cases in a test set: control the order in which Test Cases are executed inside a Test Set when using sequential execution.

IMPROVEMENT

Add a selector for screenshot viewport action in a web step: capture a piece of the viewport by pointing at an element using its css, xpath...

FIX

UI polish: the breadcrumb in test runs now includes the related test case name, the test plan column is hidden from a test set's test cases list, and the certification course link opens the right localized page.
Environment cloning: cloning a project no longer drops the environment's init scripts.
Mobile build uploads: large APK and IPA uploads no longer time out during a mobile build transfer.
Steadier test runs: a batch of reliability fixes across selector resolution and frame handling cut down on flaky failures.

Thunders Cloud

Inbox, test case activity, and a restructured navigation sidebar

TL;DR

Failed runs now land in an Inbox instead of getting missed, test cases get an activity log, and the sidebar's been restructured. We also fixed a batch of smaller issues in test runs, mobile testing, and File Compare along the way.

FEATURE

Inbox: Thunders now has a new notification center where it tells you when a run fails across test cases and test sets, as long as you're the owner.
Test case activity: every change to a test case, who made it and when, now shows up in an activity log. Useful the next time a test starts failing and you need to know what changed.
A new navigation sidebar built around focus: daily surfaces like Test cases, Test runs, and Test sets stay up front, a new org-level Inbox surfaces what needs attention across projects, and set-once config moves into project Configure section.
See what you'll be charged, before you confirm: plan changes show the exact price up front, and yearly billing is available directly at checkout.
Close Tab by number: the Close Tab Web step accepts a tab number, for tests that open more than one tab and need to close a specific one.
Missing mobile build? Fix it inline: a run with no app build configured blocks clearly and lets you upload the APK or IPA on the spot.
Thunders AI keeps your draft: what you were typing is still there after a reload or reopening the panel.
Scroll action: author a scroll action inside a nested scrollable container, like a virtualized grid.

IMPROVEMENT

A real diagnosis during project creation and environment setup: the access check now says whether it's DNS, TLS, or a firewall blocking your app, instead of failing silently.
Faster Jira Data Center setup: connecting no longer asks for a project or issue type you can't know yet.
Thunders MCP identifies itself: it shows up as "Thunders" in your MCP client now.
Credit usage, more complete: mobile, suggestions, and Thunders AI usage now show up in your credit breakdown.

FIX

Test case run status refreshes on its own now. No reload needed.
The runs grid no longer crashes when a row has no data.
The status filter now applies correctly to different runs status inside a test group.
Read-only run pages load without waiting on an unrelated billing check.
Stuck runs: a run can no longer get stranded in "Running" forever.
Native dialogs stay visible during plain test runs.
Console logs resolve the actual URL of a failed resource now.
The empty Runs page stopped blinking, and its Execute button works correctly.
Renamed or deleted test cases tell you what happened and redirect you, instead of failing quietly.
Test case source is recorded correctly when a test case comes from a native MCP provider.
Range sliders are driven properly during a run instead of throwing.
Masked date fields fill in their own format now, like DD/MM/YYYY, instead of ISO.
File Compare duration: finding rows no longer a duration.
File Compare's PDF extraction is layout aware now.
File Compare's scope: findings stick to the guidance written on that step, not the whole page.
Xray Data Center sync is fixed, and the sync time renders in the right timezone.
Device pools: the newest pool is no longer treated as the default.

Thunders Self-Hosted

v2026.08.10

TL;DR

Sync runs to Xray Data Center, auto-provision users from Entra ID groups, resume Hot Reload after edits, work with an expanded Thunders MCP toolset, and pick up a security fix that makes upgrading a priority this week.

FEATURE

Xray Data Center sync: sync to Xray from the run properties panel now creates a Test Execution in Xray Data Center, with the same per-step statuses, screenshots, and timestamps.
Hot Reload picks up where you left off: editing certain steps during Hot Reload used to send your run back to the very beginning. Now it resumes from where you were, and sessions no longer cut off after a fixed 5 minutes.
Entra ID auto-provisioning: auto-provision users from Entra ID group membership instead of inviting them one by one.
Onboarding access check: step 3 of the setup wizard now checks that your app URL is reachable and shows a diagnosis card if it isn't, instead of failing silently.
New Thunders MCP tools: delete a test case, list a project's test sets, add or remove a test case's test-set membership by ID or name, and upload or list test assets, all directly through the Thunders MCP server.

IMPROVEMENT

JavaScript steps via Thunders MCP: the existing step-editing tools can now add or update JavaScript steps, not just other step types.
App version in the sidebar: the sidebar footer now shows the exact app version running on your deployment.
History retention restored: 6 months of history retention is restored on self-host installs.
ClickUp bug reports: creating a ClickUp bug report now offers you a list of valid destinations instead of guessing one and failing.
Loading state: opening a test that's still running now shows a loading placeholder instead of a blank blink.

FIX

Security fix: this release includes an access-control fix. We recommend upgrading promptly.
Sign-in without an invite: a user who signs in without an invite now sees a clear message instead of a confusing failure.
Run view text: fixed two bugs that could leave a run's steps unreadable: a conditional step whose check failed showed a bare "If" with no condition text, and a run that aborted mid-execution could leave every step's recap blank.
Custom connector dialog: the dialog no longer auto-dismisses while you're filling it in, which used to happen in Edge and with the Windows+V clipboard shortcut.
Reusable module steps: a reusable module's child steps now stay visible in a live run's step list instead of disappearing until you reload the page.
Test case versions: reused test case steps now expand correctly after you restore an earlier version, instead of showing empty until a refresh.
File Compare: File Compare failures now surface as bug reports in your run report, and there's no longer a length limit on the guidance text.
Steadier test runs: a batch of reliability fixes across element detection, frame handling, and test credentials that cut down on flaky failures.

Migration steps

None required. Pull the new images and redeploy, starting with the API Service (it applies any database updates automatically).
This release is published as both its version tag and :latest. Pin the version tag in production for deterministic, reviewable rollouts.

Thunders Cloud

Xray Data Center sync, Hot Reload improvements, and an expanded Thunders MCP toolset

TL;DR

This release adds native Xray Data Center sync, lets Hot Reload resume after edits and run longer, rounds out the Thunders MCP toolset, and ships a batch of run-view, connector, and reliability fixes.

FEATURE

Xray Data Center sync: sync to Xray from the run properties panel now creates a Test Execution in Xray Data Center too, with the same per-step statuses, screenshots, and timestamps you already get with Xray Cloud.
New Thunders MCP tools: delete a test case, list a project's test sets, add or remove a test case's test-set membership by ID or name, and upload or list test assets, all directly through the Thunders MCP server.

IMPROVEMENT

JavaScript steps via Thunders MCP: the existing step-editing tools can now add or update JavaScript steps, not just other step types.
Loading state: opening a test that's still running now shows a loading placeholder instead of a blank blink.

FIX

Mobile screen resolution: mobile test runs now use the device's actual screen resolution instead of a generic default, for more accurate screenshots and coordinates.
ClickUp bug reports: creating a ClickUp bug report now offers you a list of valid destinations instead of guessing one and failing.
Hot Reload picks up where you left off: editing certain steps during Hot Reload used to send your run back to the very beginning. Now it resumes from where you were, and sessions no longer cut off after a fixed 5 minutes, so you have more room on longer test cases.
Run view text: fixed two bugs that could leave a run's steps unreadable: a conditional step whose check failed showed a bare "If" with no condition text, and a run that aborted mid-execution could leave every step's recap blank.
Custom connector dialog: the dialog no longer auto-dismisses while you're filling it in, which used to happen in Edge and with the Windows+V clipboard shortcut.
Reusable module steps: a reusable module's child steps now stay visible in a live run's step list instead of disappearing until you reload the page.

Thunders Self-Hosted

v2026.08.03

TL;DR

Thunders AI keeps a browsable chat history and can bulk-create test cases, you can watch a test run while it executes, secret variables are encrypted at rest, and this image includes third-party dependency security patches.

FEATURE

Thunders AI chat history: every conversation is kept, browsable, renamable, and resumable, instead of losing context between sessions.
Bulk test case creation: ask Thunders AI to create several test cases in one request and review them all at once.
Watch a run as it happens: open a test run while it is still executing and follow it live, instead of waiting for it to finish.
"Close tab" step: tests can close a browser tab as an authored step.

IMPROVEMENT

Native tool connections: Jira, Confluence, Azure DevOps, ClickUp, Shortcut, Linear, and Notion now connect directly to Thunders. Reconnect an integration, or add a new one, to switch to the new flow; every connected tool then becomes available to Thunders AI.
New-version notice: the app now tells you when a newer version is running instead of erroring quietly in stale tabs.

FIX

Secret variables: secret test variables are encrypted at rest and never sent back to the browser, and you can now change one after creation.
Sequential execution: sequential runs now execute one test at a time instead of firing every CSV row at once.
Xray Data Center: creating a test now tells you if some steps could not be added instead of reporting success, and Gherkin imports bring their scenario text across.
Accessibility under strict security rules: accessibility checks work again on sites with strict content-security policies.
Run reports: durations no longer count page load time twice, each step shows its own screenshot, and a failed check shows the screenshot it actually looked at.
Steadier test runs: a batch of reliability fixes to waits, clicks, assertions, and URL matching that cut down on flaky failures.
Dependency security patches: patched several third-party dependency vulnerabilities.

Migration steps

None required. Pull the new images and redeploy, starting with the API Service (it applies any database updates automatically).
This release is published as both its version tag and :latest. Pin the version tag in production for deterministic, reviewable rollouts.

Thunders Cloud

Resume any Thunders AI conversation, create test cases in bulk, and watch all your tests run in real time

TL;DR

This release lets Thunders AI keep a browsable, renamable chat history and bulk-create test cases in one request, lets you watch a background or queued test run as it happens, makes integration connections personal to you instead of shared project-wide, and adds iOS testing support alongside a wide batch of reliability and UI fixes.

FEATURE

Thunders AI chat history: Thunders AI keeps a chat history you can browse, rename, and resume, instead of losing context between sessions.
Bulk test case creation in Thunders AI: ask Thunders AI to bulk-create test cases in one request with any context, and get them all back at once.
Watch a run as it happens: open a background or queued test run while it's still executing to see it play out in real time, instead of waiting for it to finish.
iOS testing support: upload iOS .ipa app builds from the new environment dialog and run tests against iOS devices.
Mobile "Dismiss Keyboard" step: add a step that closes the on-screen keyboard on mobile, so it stops covering the buttons or fields your test needs to interact with next.

IMPROVEMENT

Mobile execution settings: the test run now shows exactly which mobile settings a run used, and you get more control over how runs queue when a device isn't immediately available.
Personal, per-project integrations: connecting an integration is now personal and scoped to your project, instead of shared across every project member. Every integration you connect becomes available to Thunders AI, to report bugs to it and to pull context when authoring tests.
Device pool details: copy device pool and device IDs directly from the Devices UI, CI runs now validate the requested device pool or SKU before starting, and batch execution accepts a SKU/pool override.

FIX

Credential variables: secret variables can now be edited after creation. Type a new value, or leave the field blank to keep the current one.
Steadier test runs: a batch of reliability fixes to waits, clicks, drag-and-drop, assertions, and mobile device sessions that cut down on flaky failures.
File Compare Step: File Compare durations and highlights, test report load-time durations, and accessibility reports on passing runs now report correctly.
Accessibility under CSP: accessibility scans now run correctly for organizations with strict content-security policies.
Sequential execution: fixed sequential execution using a CSV file for a single test case.
Ignored-URL allowlist: URLs are now matched by substring instead of exact domain, so more of your ignore-list entries work as intended.
Device picker: only devices with remote access enabled are shown when selecting a device or pool.
Xray Data Center test creation: creating a test in Xray Data Center now tells you if some steps could not be added, instead of reporting success.
Xray Data Center Gherkin import: importing a Gherkin test from Xray Data Center now brings its scenario text across.
UI polish: improved empty-state illustrations, copy, and sizing across Test Cases, Test Plans, and Devices. Credential values are now masked, conditional jump targets are fixed, and deterministic and failed-assertion steps show their own screenshots. Also fixed navigation after running a single test set, a corrected Xray Cloud API keys link, and other small copy and style fixes.

Thunders Self-Hosted

v2026.07.27

TL;DR

Run across multiple replicas without pinning traffic to one instance, get step-quality suggestions before and after every run, execute Test Plans the same way as Test Sets, rate Thunders AI answers from the chat, and pick up a CORS fix for the self-hosted web console.

FEATURE

Multi-replica scale-out: real-time updates now work across multiple replicas without pinning traffic to a single instance, so you can scale out horizontally. See the deployment guide's SignalR transport section for the Redis backplane configuration.
Step-quality suggestions: get suggestions and ready-to-apply rewrites before and after a run, for more stable tests. Now generally available.
Bulk suggestions via Thunders MCP: read step-quality suggestions across many test cases at once and apply the ones that come with a ready rewrite, directly through the Thunders MCP server.
Test Plans can now be executed: Test Plans inherit the same structure as Test Sets: they can be executed, they get an owner, and they show their own test cases.
Test Set owners: every test set now has an owner, shown in the list and its properties panel, same as test cases. The creator becomes the owner by default and you can change it.
Thumbs up/down feedback on Thunders AI: rate a Thunders AI message right from the chat, in both the test case editor and the global assistant.

IMPROVEMENT

Test-case-level accessibility report: the accessibility persona can produce one report for the whole test case instead of one per step, when reporting mode is set to comprehensive.
Console logs: the Console Logs button is greyed out when a run has no logs, instead of downloading an empty file.

FIX

Self-hosted web console CORS: the self-hosted web console's origin is now allowed through CORS, so the console can reach the API from its configured URL.
Step-edit conflicts: editing a step now flags when a different user changed the test case first, instead of silently overwriting their work.
Drag-and-drop reliability: clicks and drags now land on the correct target, including native HTML5 drag widgets.
Duplicate step execution: a step no longer runs twice by replaying a stale result from a previous attempt.
Steadier test runs: more reliable screenshot capture, natural language step recognition, Visual Compare detection, and faster failure when a browser session is lost.

Migration steps

None required. For multi-replica deployments, set the SignalR Redis backplane connection string to take advantage of the new scale-out support.

Thunders Cloud

Step-quality suggestions, executable Test Plans, and Thunders AI chat feedback

TL;DR

Pre-run and post-run step-quality suggestions are now generally available, with a new Thunders MCP tool to apply them in bulk across test cases. This release also lets Test Plans run just like Test Sets with their own owner, adds thumbs up/down feedback on Thunders AI chat messages, progresses the Mobile Testing private beta, and ships a test-case-level accessibility report alongside reliability fixes.

FEATURE

Pre-run and post-run suggestions are generally available: get step-quality suggestions and ready-to-apply rewrites before and after a run, for more stable tests.
Thunders MCP: apply pre-run and post-run suggestions in bulk: read step-quality suggestions across many test cases at once, apply the ones that come with a ready rewrite, and leave the rest for a person to decide.
Test Plans can now be executed: Test Plans now inherit the same structure as Test Sets: they can be executed, they get an owner, and they show their own test cases.
Test Set owners: every test set now has an owner, shown in the list and its properties panel, just like test cases. The creator becomes the owner by default and you can change it.
Thumbs up/down feedback on Thunders AI: rate a Thunders AI message right from the chat.

- Device Pools Management: create Android or iOS device pools from the Devices page, and select a specific pool at execution time.
- New mobile execution settings: set connectivity and device permissions for a run.
Test case level accessibility report: the accessibility persona can now produce one accessibility report for the whole test case, instead of a separate report per step, when its reporting mode is set to comprehensive.

IMPROVEMENT

Apps: screenshots now live at the app level. The old project-level screenshot code has been removed.
Model availability signal: see when the AI model behind a step is temporarily unavailable instead of a run just failing.
Test Run Console Logs: now disabled when a run has no console output, instead of downloading an empty file.

FIX

Drag-and-drop reliability: clicks and drags now land on the correct target, including native HTML5 drag widgets and vision-based coordinate fallback.
Duplicate step execution: a discovery step no longer runs twice by replaying a stale result from a previous attempt.
Step-edit conflicts: we only flag a conflict when someone else actually changed the test case, not on your own concurrent edits.
Screenshot capture failures: a failed screenshot capture now shows a clear error instead of a generic "model unavailable" message.
Natural language step recognition: random-value generation, exact-word-count phrases, wait-for-disappear, and off-enum AI issue types are now classified and handled more reliably.
Visual Compare and accessibility scans: improved detection for color-blind-safe comparisons and high-DPI baselines, clearer guidance when a baseline needs rescaling, and accessibility scans now run at the right time to match the screenshot.
Downloads and mobile API steps: CDP downloads now honor your HTTPS-error setting, and mobile API-call steps return the real HTTP status instead of a placeholder.
UI polish: fixed devices tab and test-run empty states, the Thunders AI page URL, and a copy issue when reading an uploaded file in Thunders AI.

Thunders Self-Hosted

v2026.07.20

TL;DR

The first calendar-versioned self-hosted release. Connect your own MCP servers to Thunders AI, delete test runs, report bugs straight into your connected tracker, and pick up a batch of export and reliability fixes.

FEATURE

Calendar-versioned images: self-hosted images are now numbered with a calendar version, so you can tell at a glance which release you're running.
Custom MCP connectors: connect your own MCP servers to Thunders AI alongside the built-in integrations, from a redesigned connectors page. Self-hosted deployments can also allow plain-HTTP connectors for internal tools not served over HTTPS.
Soft-delete test runs: delete a standalone test run or a full test-set run instead of it being permanent. Deleting a set run recalculates its pass rate and status, and deleted runs stay recoverable.
Report bugs through your connected tracker: reporting a bug from a test run, or asking in chat, now opens a ticket directly with your connected integration (Notion, Linear, Jira, ClickUp, Azure DevOps, and more).
Apps get a full details page: Apps now open in a full page, like Environments.

IMPROVEMENT

Thunders Copilot is now Thunders AI: all user-facing copy now says "Thunders AI." Same capabilities, new name.
Personal integration credentials: connecting an integration is now personal and scoped to your project, instead of shared across every project member.
Smarter dropdown handling: the improved dropdown interaction handling is now enabled by default on all test runs.

FIX

PDF report exports: exports now include the full document instead of just the first page, with aligned step numbering, the right font, and your organization logo rendering correctly.
"Generate random" steps: steps that generate a random value now produce a new value each run, instead of repeating the same one.
Interrupted vs. failed runs: a run whose browser crashes is now marked interrupted instead of failed, so you can tell a real bug from an environment hiccup.
S3-compatible storage: fixed the S3 configuration validator and template to match renamed self-host keys, so S3-compatible stores work correctly.
UI polish: "scroll up" and "scroll down" steps are recognized correctly, plus fixes for a flickering report popover, blank list grids, double-firing hotkeys, and retry groups not loading their attempts.

Migration steps

None required. Pull the new images and redeploy, starting with the API Service (it applies any database updates automatically).

Thunders Copilot is now Thunders AI: building the experience into a colleague you can tag anywhere to get your testing work done.
Dropdown elements handling: the new dropdown interaction handling is now enabled by default on all test runs.
Personal integration credentials: connect to integrations at the personal-project level instead of being shared across the whole organization.

FIX

PDF report exports: test run PDF reports now export the full document instead of just the first page, keep step numbering aligned, use the right font, and render org logos instead of failing.
"Generate random" steps: steps that generate a random value now actually produce a new value each run, instead of repeating the same one.
Natural language scroll: a step written as "scroll up" or "scroll down" is now recognized as a scroll action instead of unknown.
Interrupted vs. failed runs: a run whose browser process crashes is now marked interrupted instead of failed, so it is easier to tell a real bug from an environment hiccup.
Thunders AI fixes: stopped Thunders AI refusing to make edits after an in-editor test run, and fixed it failing to browse websites during a conversation.
UI polish: fixed a flickering report popover, blank list grids on some pages, global hotkeys double-firing over open dialogs, a Firefox crash on logout, retry groups not loading their attempts, invalid app names being accepted, and billing copy that did not match the website.

File Compare dual-pane viewer, a credits chart, and steadier runs

TL;DR

File Compare gains a side-by-side viewer, the analytics dashboard adds a daily credits chart, and runs handle lost browser sessions more gracefully.

FEATURE

Credits chart: the analytics dashboard now shows a bar chart of credits consumed per selected period.

IMPROVEMENT

File Compare viewer: File Compare (beta) now has a side-by-side matches and mismatches viewer, so you can see both files and jump straight to a flagged difference in either pane.
Detach test case source: detach a test case's source, with a refreshed Xray source card.
Parallelism cap: max parallelism is now capped by test case count instead of CSV row count.

FIX

Session-lost runs: browser crashes and lost sessions now fail fast as an interrupted run, instead of cascading into an opaque exception.
Run duration: fixed test-set run duration being inflated by idle-gap time.
UI polish: aligned modal buttons, tree indentation, sidebar labels and icons, and accessible step controls, and cleared a stuck "saving test steps" toast.

Variables across a test set, file comparison, and JavaScript steps

TL;DR

Prerequisite Test Case in Test Set now pass on what it creates, plus a new File Compare step, sequential execution behavior, and JavaScript steps.

FEATURE

Prerequisite variables: prerequisite tests hand off runtime variables to every downstream test in the set.
File Compare step (beta): compare expected vs actual files with AI guidance and variable interpolation, without leaving the runner.
Sequential execution: run a set or campaign in predictable alphabetical order, stopping at the first failure or continuing through.
JavaScript steps: write and run JS in a built-in editor, isolated in its own tab, with access to variables and prior results.
Thunders MCP: expanded toolset to clone a test case, update a step, insert a step, and update an environment.

IMPROVEMENT

API body editor: the API step JSON body is a full variable editor, with autocomplete, highlighting, and inline references.
Resolved variable preview: see the real runtime value a step will use instead of raw tokens.
Ownership: reassign test case ownership individually or in bulk.
Domain allowlist: skip noisy third-party calls during page-load checks, per project.

FIX

Variable rename: renaming a variable from project or environment variables now updates every step that uses it.
Editing conflicts: if a test case changed since you opened it, you now get a clear version-conflict message instead of a generic error.
Step type preserved: editing a browser step keeps it as a browser step instead of reverting to an AI step.

Thunders Cloud

API testing upgrade, Thunders Copilot reasoning, and run comparison

TL;DR

API testing gains a full response inspector and assertions, Thunders Copilot streams its reasoning, and you can compare two runs side by side.

FEATURE
