Session Lost After Replit Restart
Users are logged out when your Replit app restarts or scales. Session data stored in memory is lost, forcing users to re-authenticate. This is critical for production apps.
Replit deployments can restart unexpectedly, and memory-based sessions don't persist across those events.
Common Causes
- Sessions stored in-memory instead of persistent storage
- No session database configured
- Redis session store not connected or credentials missing
- PostgreSQL sessions table not created
- Session timeout too short or not configured
How to Fix It
Switch from memory-based sessions to a database backend. Use Replit's PostgreSQL or connect to Redis. For Spring Boot, configure spring.session.store-type=jdbc or =redis with appropriate datasource properties. Ensure the sessions table exists and database credentials are in Replit Secrets.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

What's the easiest way to persist sessions?
Use Replit's built-in PostgreSQL and configure Spring Session JDBC storage
Do I need Redis for sessions?
No, PostgreSQL works fine for most apps. Redis is better for high-traffic scenarios
