If your Replit app works in the editor but isn't safe to launch, we harden it: real auth, secrets moved out of the client, rate limiting, tests, and monitoring. Fixed price agreed up front, a working demo every week, full code and IP transfer. We find every blocker or the audit is free.
Replit is a fast way to get from idea to working app. The editor previews, the deploy button ships, and for a demo that is enough. The problem starts when real users, real money, or real data show up. The things that keep an app safe and stable in production are usually the things Replit never forced you to set up: real authentication, secrets handling, rate limits, tests, and monitoring. The app looks done. It is not yet safe to launch.
This page is about getting your Replit project from "works on my screen" to "I can put this in front of customers and investors." Fixed price, senior engineers, and a guarantee. If you only want to know whether your build is risky in the first place, read is Replit safe first, then come back.
These are the failure modes we see again and again in AI-built and vibe-coded apps, Replit included. None of them show up in a demo. All of them show up in production.
We do not start with a quote and a six-week silence. We start with a fixed-price Week-1 build audit at $4,000. In that week we go through the whole codebase, find every blocker, and hand you a plan: what is broken, how bad it is, and exactly what hardening costs. You decide with full information.
If you move forward, full hardening starts from $14,000, fixed price, agreed before we write a line of code. Compare that to a US or UK agency quoting $60,000+ with an open hourly meter that keeps running.
| Step | What you get | Price |
|---|---|---|
| Week-1 build audit | Full codebase review, every blocker found, fixed plan and cost | $4,000, fixed |
| Due-diligence rescue audit | Deeper audit, credited in full toward the rescue | $2,500, credited |
| Full hardening / rescue | Auth, secrets, rate limits, tests, monitoring, production deploy | From $14,000, fixed |
| AI code security audit | First 15-minute audit | Free |
During the rescue we fix the real things, not cosmetics: move secrets out of the client, put real auth and authorization in place, lock down the database, add rate limiting, write tests so changes stop being a gamble, and wire up monitoring so you know when something breaks. Then we deploy it on infrastructure that holds up. See the full prototype-to-production service for the detail.
Same terms on every job, written down before we start:
We find every blocker or the audit is free. That is the whole deal. If you pay for the audit and we miss the things that would stop you launching, you do not pay for the audit. We carry the risk of the audit, not you. The teams behind this work have shipped production code for ShapeShift, CoinDesk, Komodo, SALT, and WallStreetBets, so the bar for "ready" is set by real launches, not a checklist.
Two free ways to find out. Run the production-readiness check on your own app and see where the gaps are. Or read the is Replit safe guide for the Replit-specific risks. If you want eyes on the actual code, the first 15-minute AI code security audit is free, and if you are weighing a rebuild against a fix, read fix or rebuild a vibe-coded app before you spend anything.
Book a free 15-minute call. Tell us what you built and what you are trying to launch. We will tell you straight whether it is a quick fix or a real rescue, and what it costs. No meter, no surprises. Start with the Week-1 build audit and you will know exactly where you stand in seven days.
Yes. We harden Replit apps for launch: real auth, secrets moved off the client, rate limiting, tests, monitoring, and a deploy that holds up under real traffic. We start with a fixed-price Week-1 build audit at $4,000, then full hardening from $14,000, fixed price agreed up front.
Replit gets you to a working app fast, but it does not enforce the things production needs. Common gaps are API keys in the client bundle, no real authentication, no rate limiting, no tests, an open database, and no monitoring. They never show up in a demo, only with real users.
A fixed-price Week-1 build audit is $4,000 and tells you every blocker plus the exact hardening cost. Full hardening starts from $14,000, fixed price. A US or UK agency typically quotes $60,000+ on an open hourly meter. The first 15-minute security audit is free.
Then the audit is free. Our guarantee is that we find every blocker or you do not pay for the audit. You also get senior engineers only, a working demo every week before each payment, 100% code and IP from day one, and a 30-day warranty.
Usually fix. Most Replit builds have a sound core and a few dangerous gaps, which is cheaper to harden than to rebuild. The Week-1 audit tells you which case you are in. If you want to think it through first, read our guide on whether to fix or rebuild a vibe-coded app.
