Every change to your app is a leap of faith. TesterHat tests your flows, forms, and pages automatically — so you can ship with confidence, not anxiety.
Built for founders who build with
“I ship it and pray.”
You deploy and hope nothing broke. Your users are your only QA team.
“I’m scared to touch anything.”
Every change could break what already works. So you stop improving.
“If you find any breaking issues, let me know.”
You ask your users to find your bugs. That’s not a strategy — it’s a gamble.
Three steps. Sixty seconds. Zero setup.
No code access. No setup. No configuration. Just the URL of your live app.
It finds your flows — login, signup, forms, navigation — and tests them like a real user would.
Get a clear report of what works and what doesn’t. Export it for your devs or your AI coding tool.
From forms that don't submit to links that go nowhere — TesterHat catches what you can't see.
TesterHat navigates your app like a real user. It finds login forms, signup flows, and buttons — then tests if they actually work.
Broken links, slow pages, security issues, accessibility problems — all checked automatically in one click.
AI analyzes your design for usability issues that you might not notice — but your users definitely will.
TesterHat doesn't have to be perfect. It has to be good enough, available at 2am, and cost less than a coffee per week.

No. Paste your URL, hit check, see results. No account, no credit card, no setup. Sign up later if you want to save your results and monitor over time.
No. TesterHat only accesses your public URL — the same thing your users see. It doesn’t read your source code, your repo, or your database.
No. TesterHat only reads and interacts — it doesn’t modify data, submit real transactions, or change anything. It’s read-only testing.
Especially for you. TesterHat was built for founders who build with tools like Lovable and Bolt. No testing knowledge required — just paste your URL and we handle the rest.
It won’t — no tool catches 100% of issues. But it catches the common ones that cost you users: broken forms, dead links, slow pages, and UX problems. That’s a huge improvement over finding out from your users.
