RESCUE · REPLIT

Replit app not deploying or breaking live? We fix it.

When a Replit app works in the workspace but fails after publishing, the cause is usually one of three things: the server listens on localhost instead of 0.0.0.0, production secrets were never added to the published app, or the home page is too slow for the health check. VibePitstop fixes Replit apps at fixed prices, starting with a $149 diagnosis credited toward any paid job.

Why Replit publishing fails

Wrong host or port. Published apps must listen on 0.0.0.0. If .replit lists ports, automatic detection is off and one port needs externalPort = 80 with a localPort that matches your server.
Secrets missing in production. Replit's docs note that secrets set in the editor do not automatically carry over to the published app. Missing values show up as failed logins, failed payments or database errors.
Slow start. If the home page does heavy work before responding, the health check can time out.
The process exits. A published web app must keep a long-running server process.

Check the Logs tab in the Publishing pane first. The last lines before the failure usually name the problem. Source: Replit publishing troubleshooting.

What else breaks after launch

Authorization only in the UI. Agent-built apps sometimes hide admin buttons but never check the role on the server route.
Keys in the front end. Any key sent to the browser is public. Server-only keys belong in secrets, read on the server.
Stripe on test keys, or webhooks unverified. See Stripe webhook not working.
