If it runs somewhere, Thunders can test it
Test the complete user journey, not isolated pieces
A real customer journey rarely stays in one system. It can start in your web app, move through a mobile experience, call an API and finish in an internal admin panel. Thunders lets you automate that entire journey in one platform.

Old ways
Building got faster. Testing didn't.
The AI-speed gap
Development accelerated with AI. QA did not. The bottleneck moved from writing the feature to proving it works.
The maintenance tax
Broken selectors, re-runs, triage. Upkeep outgrows the suite until the suite gets abandoned.
QA can't scale by hiring
Coverage has to grow every sprint while the team stays the same size, and what to test stays locked with the people who know the product.
The DIY trap
AI makes test creation easy. Running, maintaining, reporting and evidencing those tests, plus the infrastructure behind them, is still your job.
Thunders’ way
Tests that keep up with your product
Tests that survive your releases
The test follows intent, not selectors. UI changes are absorbed at runtime; deeper breakages heal in one click, and every heal is visible. You hear about bugs, not broken locators.
Anyone can write tests engineers trust
Plain language on the surface. Under every step: the screenshot, the console, the reasoning.
Personas with opinions
Passing isn't the same as good. QA, Accessibility, UX, SEO and security personas each hold the journey to their own standard.
Passing isn't the same as good.
Personas with opinions
Each persona holds the journey to its own standard, the way a specialist would, and reports what you didn't ask for: inaccurate alt text, a typo, an inconsistent screen, a click that succeeded but threw an error.
Accessibility Tester
Thinks like users with real-world constraints and compliance requirements
Product Manager, B2C platform
Standards & technical compliance - Ensures your site meets WCAG 2.1/RGAA standards and works with screen readers and assistive technologies.
Navigation & interaction - Verifies users can navigate and interact with your site using keyboard, voice control, or other assistive devices without barriers.
Visual accessibility - Checks that all content has proper contrast, readable text, and meaningful alternatives for users with visual impairments.
Media accessibility - Confirms videos have captions, audio has transcripts, and animations are safe for users with seizure or motion sensitivities.
Updated continuously as accessibility standards evolve.
Security Tester
Scans with a hacker mindset, but acts with purpose and precision
Security Engineer, Fintech startup
Input validation & injection protection - Tests for SQL injection, XSS, and other code injection vulnerabilities that could compromise your database and user data.
Data & infrastructure security - Ensures sensitive information is encrypted, SSL certificates are valid, and server configurations prevent unauthorized access.
Compliance & standards - Assesses adherence to OWASP guidelines and industry security standards to ensure regulatory compliance.
Updated continuously as new threats and standards emerge.

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.
Wassim Jouini
CTO @LegalPlace
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.
Hanen Khalfaoui
QA Manager @Infopro Digital
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.
Jean-Olivier Penin
Co-founder @B/Acceptance
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.
