Replit agent fixes
Moving off Replit onto dedicated infrastructure (Vercel, Supabase, AWS) ensures database connection pooling, lower latency, and professional CI/CD pipelines.
Export code and migrate database schema to persistent PostgreSQL / Supabase clusters.
Remove in-memory session bottlenecks and configure enterprise secret management.
Set up production deployment with automated GitHub Actions and custom domain DNS.
Replit is an excellent place to build and a constrained place to run. The constraints that do not matter during development become the whole problem once people arrive.
The migration itself is well-trodden: the database moves to a managed PostgreSQL service, the application to a normal host, files to object storage, and secrets into proper environment configuration.
For a typical prototype this is days rather than weeks. The variable part is not the move — it is how much of the application assumed it would always run in one place with local disk and permanent memory.
The expensive version of this project is the one that starts when the app is already failing under load, because then you are migrating and firefighting at the same time, with customers watching.
If you can see growth coming — a launch, a campaign, a partnership — the move is far cheaper done a month early than a week late.
Moving production off Replit does not mean leaving the tool. It remains a good environment for prototyping the next feature before it goes into the real codebase.
The distinction worth holding is between where you try things and where your customers live. Those being the same place is the actual problem, not the platform.
Only for production. It remains a good place to prototype the next thing. The problem is customers living in the same environment you experiment in, not the tool itself.
Days rather than weeks for a typical prototype. What varies is how much of the app assumed permanent memory and local disk, which is where the work actually is.
