Fix and launch your Replit app

    Replit Agent built it and it runs. Senior engineers make it safe, separate test data from real data, and set it up so it keeps running when you have real users, for a fixed price.

    Why Replit apps stall before launch

    Replit gives you an editor, a database, secrets and hosting in one place, and Replit Agent can build a full-stack app from a description. It's a great way to get something running without setting anything up.

    The convenience has a cost later. Development and production often share one database, the app can depend on Replit-only services that make moving harder, and nobody has looked at what happens under load, on a cold start, or when the agent rewrites a file it shouldn't.

    What usually breaks in Replit apps

    The problems we look for first. Most apps have two or three of them.

    • Test data and real data in one place

      The same database serves development and the live app, so a test or an agent run can change real customer records.

    • No backups you've tested

      Nobody has restored the database from a backup, so nobody knows whether it works.

    • Secrets and access

      API keys copied into code or shared across environments, and admin routes that only check whether someone is logged in.

    • Slow or costly hosting

      The deployment type doesn't match the app: cold starts on every visit, or an always-on machine for a few users a day.

    • Tied to Replit

      Login, storage or the database depend on Replit-specific services, which makes a later move or a second developer harder than it needs to be.

    How we fix it

    Review first, then a fixed quote, then the work, with a demo every week. How a rescue works

    1. 1

      We separate development from production, set up backups and test a restore before we change anything else.

    2. 2

      We fix access checks, move secrets out of the code, and choose a deployment setup that fits your traffic and budget, on Replit or elsewhere.

    3. 3

      If you want to move off Replit, we plan it in steps so the app stays live throughout.

    Prices

    The same fixed prices for every Replit app. The review ends with a fixed quote for anything bigger.

    Frequently Asked Questions

    Common questions about fixing a Replit app

    Often, yes. Replit Deployments can run a production app. We'll tell you plainly if your app would be cheaper or more reliable somewhere else, and move it only if you want us to.

    Yes. We replace any Replit-only services, set up the database and hosting on your own accounts, and move it without downtime for your users.

    A $149 review with a fixed quote, $249 for one blocking problem, or a launch sprint from $1,299. A move to new hosting is quoted after the review.

    No. Invite us to the Repl or export the code to GitHub. You keep ownership of everything and can remove our access when we finish.
