Dragonfly is a Redis-compatible, high-performance in-memory database. It's a modern alternative to Redis with 30K+ GitHub stars, typically 25% less memory usage, and up to 70% better performance.

## About Hosting

Dragonfly runs as a single container on Railway with:
- Port: 6379 (Redis-compatible, automatically managed by Railway)
- No external dependencies - it IS the database
- ~48MB Docker image fits any tier

## Why Deploy

- Drop-in Redis replacement - same protocol, zero code changes
- Better performance - up to 70% faster than Redis
- Lower memory usage - typically 25% less
- Single binary deployment
- Massive community (30K+ GitHub stars)

## Common Use Cases

- Session cache for web applications
- Real-time analytics and counters
- Leaderboards and rate limiting
