Situational
Run full-stack apps globally at the edge. Deploy anywhere in 30+ regions.

Free tierHas API
Fly.io is the best platform for globally distributed applications. Running full apps at the edge across 30+ regions is genuinely powerful. The CLI-first workflow and Docker-based deployment give full control. But it is more complex than Railway or Render, and only worth it if global distribution matters to your app.
What's great
- Run full applications in 30+ global regions
- Docker-based — full control over your runtime
- Distributed PostgreSQL and SQLite at the edge
Watch out for
- More complex than simpler hosting platforms
- Documentation can be inconsistent
- Pricing can be unpredictable for multi-region deployments
