It runs on Replit. That's the dependency to remove.

What Replit does well

Replit Agent produces full-stack applications rather than frontends, with a database, a server and a deployment already working. For a solo founder that's remarkable leverage. The problems appear at the boundary: the app is often coupled to Replit's environment in ways nobody chose deliberately.

• Node/Express or Python/Flask
• React frontend
• Replit's built-in Postgres or key-value store
• Replit Secrets
• Replit Deployments and Object Storage

• 01

  Platform coupling nobody chose

  Storage, secrets and database access go through Replit-specific interfaces. Moving requires finding every one of them, and they're rarely centralised because there was never a reason to abstract them.

• 02

  State on the filesystem

  Uploads and generated files written to local disk, which works until the container restarts or a second instance exists. This one silently deletes customer data rather than throwing an error.

• 03

  A single process doing everything

  Long-running work — imports, emails, report generation — runs inline in the request. It holds up under demo traffic and falls over under real concurrency.

• 04

  Dependencies pinned to nothing

  The environment was reproducible because it was one container that never rebuilt. Elsewhere, an unpinned dependency tree is a build that works today and not tomorrow.

• 01

  Secrets in the client bundle

  API keys inlined into frontend code because the prototype had no server to hide them behind. Anyone can read them with view-source, and rotating them is the first thing we do.

• 02

  Authorisation checked in the UI

  The admin button is hidden from non-admins, and the endpoint behind it is wide open. Hiding a control is not access control, and this is the single most common serious finding.

• 03

  No migration history

  The schema exists because someone clicked through a dashboard. There's no record of how it got that way and no safe path to change it, so the first production schema change is terrifying.

• 04

  Nothing to catch a regression

  No tests, so the next AI-assisted edit that breaks checkout is discovered by a customer. This is what makes generated codebases feel fragile — not the code quality, the absence of a safety net.

1. 1

   Audit — 3 to 5 days

   We inventory every platform-specific dependency, every filesystem write and every inline long-running task, and report what portability actually costs. Written and ranked.

2. 2

   Make it portable

   Containerised build with pinned dependencies, environment configuration via standard variables, and storage moved to S3-compatible object storage behind an interface.

3. 3

   Real database and migrations

   Managed Postgres with versioned migrations, connection pooling, and a backup and restore procedure that has actually been tested rather than assumed.

4. 4

   Split the work out

   Background jobs onto a queue with retries and dead-lettering, so an import or an email send can't hold a request open or vanish on restart.

5. 5

   Deploy, monitor, hand over

   Fly, Railway, AWS or your own account with staging, CI, Sentry and alerting — plus documentation for a team that isn't us.

FAQ

Replit Agent to Production: your questions.

• Do we have to leave Replit?

  Not necessarily. For low-traffic internal tools staying is defensible. The reasons to move are compliance requirements, cost at scale, and needing infrastructure Replit doesn't offer — the audit tells you whether any of those apply to you yet.

• Will our data come across?

  Yes, with a migration plan and a rehearsed cutover. We run the export and import on a copy first and reconcile row counts and checksums before touching anything live.

• Can our team keep working during the migration?

  Yes — we work in branches against your repo and cut over once staging is verified. Feature work continues; we merge rather than freeze.

• What if the app was mostly written by the Agent?

  That's the normal case and it's fine. Generated code is a starting point like any other; the audit judges what's there, not who wrote it.

• Bolt to ProductionBolt gets you to a running product in an afternoon. We add the things it never had to think about — real auth, migrations, payments that can't double-charge, and a test suite that survives your next prompt.Read
• Lovable to ProductionLovable is very good at producing an app that looks and feels finished. What it can't know is which of your tables must never be readable by another customer — and that's the finding that stops enterprise deals.Read
• v0 to Productionv0 output is the best-looking starting point in the category, and it is almost entirely frontend. The work is building the system underneath it — and doing that without throwing away the UI you liked.Read
