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
SQLITE_CANTOPEN: unable to open database file
Error: no such table: users
SQLITE_ERROR: database disk image is malformed
Database file not found
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

Full-stack developer experienced in fixing and deploying AI-generated apps from Lovable, Bolt.new, Cursor, and Replit. I specialize in debugging Supabase integration issues (auth flows, RLS policies, database connections), fixing broken deployments, resolving routing/blank screen problems, and cleaning up messy React/Vite codebases. I also build production apps with the Claude API and have shipped a Mac desktop dev tool (Nexterm from scratch. Based in Hong Kong, fast turnaround.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.
You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
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.
