Replit gets founders to a working product fast, usually on Node.js or Python with PostgreSQL. The trouble starts when real users, payments and investors arrive: the AI goes in circles, security was never checked, and every new feature breaks an old one.
Cosmos Studio picks up Replit projects at this stage. We review the code and database, fix what is risky, finish the features you need and redesign the UX where it matters, then set the app up on hosting you own. Frontend and design are done in-house; backend, cloud and security work is done with senior engineers we work with on every project.
These are the problems founders bring to us most often after building with Replit.
The agent got you to a working app, but new features now take longer than building them by hand.
Environment variables, database access and API keys were set up quickly and never reviewed.
You want your own hosting on AWS, Vercel or another cloud, but do not know how to move safely.
Authentication, roles and Stripe flows fail for real users.
Performance drops as users and data grow, and there is no monitoring.
The product works, but the design does not match the quality buyers expect.
You keep ownership of your code and your product. We work in your repository and explain every decision.
In 1–2 weeks we review the code, database, security, hosting and UX, and show you what is safe, what is risky and what it will take to fix.
Most AI-built MVPs do not need a full rewrite. We decide together what to keep, what to refactor and what to rebuild.
Data leaks, open database rules and broken payments come first, before any new features.
We complete missing features, clean up the UX and UI and add tests, so the product is ready for real users.
We set up production hosting, backups and monitoring and stay with you through launch.
You get clean, documented code, or we keep building with you as your product team.

We're not a freelancer who disappears after delivery. Not a 200-person agency where you'll never meet a senior. We're a boutique, embedded design team and the longer we work together, the sharper we get.
Remote-friendly team growing fast
We focus on quality over quantity

Book a Discovery CallYou only need a quick one-line bug fix, a budget below $2,000, or someone to keep prompting the AI for you.
Every rescue starts with an audit. The audit starts at $2,000 and takes 1–2 weeks, depending on the size of the product and its backend. After the audit you get a scope and estimate for the fixes, and hourly rates start at $50.
Usually not. We refactor what can be saved, rebuild only the parts that are unsafe or cannot scale, and explain every decision.
Yes. We can keep it on Replit Deployments or move it to AWS, Vercel or another cloud you own, with the database, environment variables and domain moved safely.
You do. We work in your repository and accounts, sign an NDA from the first call, and hand over everything at the end.
Yes. Our senior designers rethink flows, onboarding and the design system, so the product is ready for real users and investors.
Yes. We also take over apps built with Lovable, Bolt, v0, Cursor, Windsurf, Base44. See our vibe code rescue page for the full service.
