Plumber: Every bug in your side-project app becomes a test case

Hey Product Hunt 👋 I vibecoded a dictation app in a day, gave it to friends, and learned that the hard part isn't writing code any more. It's the loop from "someone used it and it did the wrong thing" to "fixed, without breaking something else". Plumber gives your coding agent a routine for that: 🛑 "That was wrong" in your app saves the failure as a case 🔧 /maintain fixes things on a branch ✅ A fix ships only if it passes every case saved so far, yours and your friends' It's plain Markdown with no server and no account, and your friends' data never leaves their machine unless they choose to send a report. Setup is one sentence to your agent: "Set up Plumber in this app from github.com/crocsarecool/plumber". I'd love to know where it trips up on your app.
