Paste a URL. Muggle Test walks through your web product like a real user — signup, navigation, error states, wrong inputs. Not just “does it work” but “does the experience work.” No code required. Results in under 10 minutes. Test scripts persist — replay them after every deploy to catch regressions, not just first-time bugs. Also: Muggle AI Works (MCP skill suite that adds automated QA to AI coding) and Muggle AI Teams (An agent workflow that we used when developing) Free tier. No credit card.
