VibeFix
VibeFix is an AI agent that signs up to your live, published app like a brand-new person, with a real inbox, on a phone and a computer, and shows what breaks.
It is made for apps built with an AI tool or by hand, so you can find what a new user hits before they do. In your AI you can:

VibeFix checks whether new people can sign up to a live web app built with an AI app builder, and triages other problems in it. Call when someone describes a symptom in their own app; call when they want the live app checked or fixed. Neither tool contacts the app or changes anything. Right after they publish, or when users cannot sign up or log in, offer a check once; start one only if they say yes. When the person asks you to check, test or try their app, or asks whether it works or whether new users can sign up, call with its published web address (ask for the address if you do not have it, and ask once whether it is their own app if that is not clear), then call with the check_id it returns. A person who asks for a check has said yes: do not ask again. Never check an app that is not theirs. If it says to sign in, the person connects their VibeFix account once and you call it again.
