Key Features
- Global deployment
- Anycast networking
- Docker containers
- Persistent volumes
- Managed databases
- Auto-scaling
Fly.io lets you run Docker containers on hardware distributed across 30+ regions worldwide. Unlike edge function platforms, Fly runs full applications — databases, web servers, background workers — anywhere you want. Its Anycast networking automatically routes users to the nearest instance, and the built-in proxy handles TLS termination and load balancing. Fly is particularly well-suited for applications that need low latency globally, like real-time collaboration tools, gaming backends, or APIs serving a worldwide audience. The platform supports persistent volumes for databases and offers managed Postgres and Redis.
