Test Creation

Testim was built around a recorder. You click through your app, Testim captures the steps, and Smart Locators try to keep them stable. Anything beyond a happy path usually means dropping into a JavaScript custom step. Non-technical teammates hit a ceiling fast and so does the recorder, the moment your flow involves logic, conditions, or data variation.

Thunders skips the recorder. Describe what you want to test in plain language, and Thunders translates intent into executable steps. No clicking through flows to capture them. No custom JavaScript when the UI gets clever. QA, product, and business teams write tests in the same language they already use to describe quality.

Test Maintenance

Testim's Smart Locators reduce flakiness at the locator level. They look at hundreds of attributes per element and pick the most stable one. It works until your team renames a flow, restructures a page, or changes the underlying logic. At that point, you are debugging a recorder script, and the AI cannot help you.

Thunders maintains tests at the intent level, not the selector level. When your UI changes, tests update because Thunders understands what the test is verifying not which DOM node it clicked last week. The result: less time chasing red builds, more time shipping the next release.

Coverage & Intelligence

Testim covers what you record. There is no built-in concept of testing the same flow through different user lenses (accessibility, SEO, security) without building each suite manually. The AI helps stabilize tests, not expand coverage.

Thunders ships with AI Personas: accessibility testers, SEO reviewers (alpha), security auditors (alpha), and soon personas you define. The same flow runs through multiple perspectives automatically. You catch edge cases your team would not have thought to script, before they ship.

Reporting & Integration

Testim's reporting is solid for execution data : screenshots, logs, error aggregation. But it lives inside Testim. Connecting test results to your broader engineering workflow still means configuring connectors, setting up Jira mappings, and managing API testing through a separate toolchain or paid add-on.

Thunders unifies UI testing, API testing, and persona-based audits in one platform with one report. One-click issue creation drops failures into Jira, Linear, or GitHub with full context, repro steps and screenshots. CI/CD integration is native and zero-config. No glue code, no add-ons, no separate API testing license.

Here are a few reasons why now might be the time to switch from Testim to Thunders

Interface

Built for the whole team, not just engineers who can fix recorder scripts

Testim's recorder lowers the barrier compared to Selenium, but the moment a test breaks or needs branching logic, you are back in JavaScript. Thunders gives every role on your team, QA, product, business, the same way to create, review, and run tests: plain language. No IDE. No CLI. No JavaScript fallback.

No-code, natural language interface

Native intent-based test generation from specs or user stories

Role-based access for QA, dev, product, and business profiles

API

Test your APIs in the same place, in the same language

In Testim, comprehensive API testing typically means integrating with separate tooling or stitching together custom steps. In Thunders, you describe API flows in natural language alongside your UI tests. Authentication and endpoint chaining are handled automatically. Assertions are written in natural language. One platform. One report. No vendor sprawl.

Native API testing, zero extra setup

Natural-language assertions and automatic chaining

Unified UI and API test management

Integrations

Plug into your stack, day one

Testim integrates with the usual CI/CD and issue trackers, but tests run inside its proprietary execution environment, and the AI model you train is tied to the platform. Thunders connects natively to GitHub, GitLab, Jenkins, Jira, Linear, and Xray, supports self-hosting, and avoids the vendor lock-in that comes with platform-specific AI training.

This is our QA of the future.

From the very first tests, Thunders caught real bugs in our interface — bugs that had slipped through all our standard quality processes.

Before Thunders, all UI testing was done manually. With Thunders, everything is end-to-end automated. Thunders lets us generate tests very quickly and improve the overall quality of our product.

Thunders is a whole new testing culture, not just another tool.

Automating our tests was a real challenge that classical automation simply couldn't solve. With Thunders, we were able to automate a hundred tests, with no technical expertise required.

Thunders opens up test automation to non-technical roles. Thunders bridges the gap between code and people. With Selenium, it used to take much longer.

What won me over with Thunders was the testing approach, the maturity, and the innovation.

Thunders delivers far greater resilience compared to classical automation. Thunders introduced a new variable in how we respond to RFPs — and it changes our entire economic model.

Today, Thunders is giving us a glimpse of more resilient tests and better maintainability of test suites. We run proofs of concept with Thunders to validate technologies for our clients.

Thunders enabled us to put quality and test creation in the hands of the entire product team.

Our PM teams covered 80% of our test scope in just six weeks with Thunders. After just one month, the entire team was up and running.

Tests are executable immediately and the onboarding was genuinely straightforward. Now it's the PMs who write test plans in plain language directly in Thunders.
