QA.tech is an AI QA agent that learns how your web app works — visually, the way a human tester would — then automatically runs end-to-end tests on every pull request before it merges. You describe test scenarios in plain English; the agent handles the rest, with no selectors, no test code, and no brittle CSS path maintenance. The system builds a knowledge graph of your application's structure and user flows during an initial learning phase, then uses that graph to plan and execute tests intelligently when new PRs come in. When the app changes, the agent adapts its understanding rather than throwing selector-not-found errors like traditional Selenium or Playwright suites. For small teams that can't afford a dedicated QA engineer, or larger teams drowning in flaky test maintenance, QA.tech offers a compelling pitch: describe what matters in plain language and let the agent decide how to verify it. The Product Hunt launch drew strong initial traction from indie developers and early-stage startups looking to add regression coverage without the overhead of a full testing framework.

Reviewer scorecard
“The selector-free approach is genuinely appealing to anyone who's wasted hours fixing brittle Playwright tests after a designer changed a class name. If the knowledge graph adapts to UI changes reliably in practice, this could replace an entire category of test maintenance work that nobody enjoys.”
“The code quality is surprisingly good — real shadcn components, not generic divs with inline styles. Saves me 2-3 hours per UI component.”
“AI-driven test agents have been promised before and they consistently struggle with complex stateful flows, modal dialogs, and multi-step auth. The 'adapts to UI changes' claim needs hard evidence — does it catch regressions or just re-learn the broken state? Pricing opacity is also a red flag for budget-sensitive teams.”
“Does one thing extremely well: turning ideas into working UI. It won't replace a designer, but it eliminates the blank canvas problem.”
“The end game here is tests written in intent, not implementation. The shift from 'click the button with id=submit' to 'verify the user can complete checkout' is philosophically important — it means tests survive redesigns and become living documentation of what the product is supposed to do.”
“As someone who ships design changes and dreads 'breaking the tests,' the idea of tests that understand intent over structure is appealing. If QA.tech can handle responsive layouts and dynamic content reliably, it removes one of the biggest friction points between design iterations and shipping.”
“As a creator, I can now prototype landing pages in minutes instead of hours. The Figma-to-code flow is a game changer for my workflow.”
