A Replit deployment is a build artifact, not a copy of your editor session. How the build command, run command, and secrets scope differ — and how to verify the runtime is truly separate.
A decision guide for production Replit apps comparing the built-in Key-Value store, managed PostgreSQL, and Object Storage, with trade-offs and a concrete validation pattern.
