Hey Product Hunt! We redesigned our signup button. Loved how it looked. Tested it — everything worked. Shipped it immediately. Then users started asking: “Where do I sign up?” The button was right there on the page. It just didn’t look like one to them. That kept happening. Our tests told us things worked. Nobody was testing if things felt right — whether users could find the signup button, whether error messages actually helped, whether the flow made sense. So we built Muggle Test. Paste any URL — including Vercel, Netlify, or Cloudflare preview links — and AI walks through your web product like a real user. Not just the expected flow — it enters wrong inputs, tries confusing navigation, triggers error states on purpose. You get screenshots of every step, and when something fails, the likely causes and recommended next steps. Plus a comprehensive test report with an overall health score and all issues ranked by severity — so you know what to fix first. Test scripts persist. You can replay them after every deploy and catch regressions — not just first-time bugs. Results in under 10 minutes. No code. While building Muggle Test, we also open-sourced two tools we use daily: Muggle AI Works — a lightweight MCP skill suite that adds automated QA to Claude Code, Cursor, Codex, and Windsurf. Scan your web product, import your existing test cases or product documents, auto-generate reusable test scripts. When something fails, you get a full evidence chain — diagnosis logs, screenshots, what went wrong and how to fix it. Not just pass/fail. Scripts persist across runs, unlike Playwright MCP where your agent rewrites tests every session. Uses Muggle AI tokens (free tier included). npm install @muggleai/works Muggle AI Teams — type /muggle-ai-teams and describe what you want built. The workflow triages your requirement, routes each part to the right expert agent automatically, and before development starts, tells you what you didn’t think about — the blind spots outside your expertise. When something breaks, it traces the root cause before attempting a fix. Completely free. npm install @muggleai/teams This is our public test launch. Both tools are MIT licensed. Extended Muggle AI Works trials for PH users who want to go deep. Comment or DM.
