SQLite Database Lost After Replit Restart
Your app uses SQLite as its database, and all data disappears every time the Replit container restarts or you redeploy. Users lose their accounts, settings, and all stored information. The app starts fresh each time as if it was just installed.
SQLite stores its data as a file on the local filesystem. Since Replit's deployed containers are ephemeral, that file is destroyed on every restart. This makes SQLite fundamentally incompatible with Replit deployments for production use.
This is one of the most common issues with AI-generated apps because many AI tools default to SQLite for its simplicity, without considering that the deployment environment requires a persistent database server.
Error Messages You Might See
Common Causes
- SQLite is file-based — the database file lives on the ephemeral filesystem and is deleted on redeploy
- AI defaulted to SQLite — many AI coding tools use SQLite by default because it requires no setup
- No database migration path — the app was built for SQLite and switching databases requires code changes
- Development vs production mismatch — SQLite works in Replit's development mode but fails in deployed mode
How to Fix It
- Migrate to PostgreSQL — Replit provides a managed PostgreSQL database; switch your ORM configuration to use it
- Export existing SQLite data — before migrating, dump your SQLite data to SQL or CSV so you can import it into PostgreSQL
- Update your ORM config — change your Prisma, Sequelize, Drizzle, or Knex configuration from sqlite to postgresql
- Run migrations on the new database — execute your schema migrations against the new PostgreSQL instance
- Test thoroughly — some SQL syntax differs between SQLite and PostgreSQL; test all queries after migration

Get HelpFrequently Asked Questions
Can I make SQLite persist on Replit?
Not reliably in deployed mode. SQLite stores data as a file, and Replit's deployed containers are ephemeral. You need to switch to a client-server database like PostgreSQL.
How do I migrate from SQLite to PostgreSQL?
Export your SQLite data, update your ORM configuration to point to PostgreSQL, run migrations, then import the data. Most ORMs (Prisma, Sequelize) make the switch straightforward.
Is there any file-based database that works on Replit?
No file-based database will persist across Replit deployments. Use Replit's built-in PostgreSQL or connect to an external database service.
