Setup & Time to Value

Tosca was built when enterprise software shipped on quarterly release trains. Implementation projects are heavy. Tricentis Academy exists because the platform requires formal training. Licensing is modular — separate activations for separate features — and the proprietary scripting and model-based approach means your team is learning Tosca instead of testing your product.

Thunders was built for teams that ship daily. There is no implementation project, no consultant required, no certification track. Describe your first flow in natural language and run it immediately. Most teams have a working test suite on day one.

Complexity vs. Intelligence

Tosca's model-based approach is genuinely powerful — once you have built the models. The trade-off is configuration depth: hundreds of options, nested modules, and a learning curve steep enough that "Tosca expert" is a job title. Power and accessibility pull in opposite directions, and accessibility is what determines whether your whole team actually uses the tool.

Thunders replaces configuration complexity with AI intelligence. Instead of asking your team to learn a modeling syntax, Thunders learns what your team wants to test. Natural language in, executable tests out. The complexity is handled by the platform, invisibly, so your team stays focused on quality, not tooling.

Maintenance at Scale

Tosca's Vision AI provides self-healing at the UI layer, recognizing elements visually rather than by selector. It is a real improvement over scripted automation. But maintenance at scale still requires Tosca specialists: model updates, license management, environment configuration, and a proprietary version control system that does not merge in parallel like Git. The bigger your suite, the bigger the team needed to keep it running.

Thunders maintains tests at the intent level. UI changes trigger automatic updates because the platform understands what the test is verifying, not how the UI happens to be built today. Flaky tests are detected and resolved before they pollute your results. Maintenance does not scale linearly with suite size.

Accessibility & Collaboration

Tosca is enterprise-grade and enterprise-priced, which means access tends to concentrate in a centralized QA function. Product managers, business analysts, and customer success teams are typically excluded from test creation by license cost, training requirements, or both. Quality stays siloed, and the QA function becomes a release-cadence bottleneck.

Thunders is built for the whole organization. QA engineers own the strategy. Product managers validate user flows. Business teams verify critical paths. Everyone sees the same results, in shared language, without needing to interpret model diagrams or decode proprietary syntax. Quality becomes a shared discipline, not a department.

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

Interface

Pick it up in minutes, not months

Tosca's depth is its strength and its tax. Steep learning curves, formal academy programs, and a UI built around model trees keep adoption narrow. Thunders was designed to be picked up by anyone on your team in minutes, not mastered by specialists over months.

No-code, natural language interface

AI-powered test generation from specs and user stories

Role-based access for all team profiles

API

API testing without a separate module

In Tosca, API testing typically means a separate module, separate licensing, and separate configuration. In Thunders, API flows are tested in natural language alongside UI tests; same platform, same interface, same reporting. Full product coverage without the vendor sprawl or per-feature license activation.

Native API testing, zero extra setup

Assertions and endpoint chaining in natural language

Unified UI and API test management

Integrations

Native, not "available as an add-on"

Tosca integrates broadly, but most integrations live behind configuration and consulting hours. Thunders plugs natively into GitHub, GitLab, Jenkins, Jira, Linear, and Xray from day one. Your CI/CD pipeline triggers tests automatically. Failures land as filed issues with full context. No custom glue code. No integration sprints. No proprietary version control to wrestle with.

Native CI/CD integrations (GitHub, GitLab, Jenkins)

Built-in connectors, zero maintenance

Issue tracking sync (Jira, Linear, Xray)

Standard, Git-compatible version control

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.
