Railway vs Fly.io
Neither offers a recurring free tier — Railway gives a one-time trial credit, Fly.io is pay-as-you-go. Railway prioritises deploy simplicity; Fly.io prioritises multi-region VM control.
Key differences
- Free: Railway = one-time $5 trial credit; Fly.io = no free plan, trial credit may apply.
- Billing: both usage-based — Railway by CPU/RAM/egress, Fly.io by VM resources.
- Architecture: Fly.io runs full micro-VMs across 30+ regions; Railway abstracts infrastructure away.
- Pick Railway for the smoothest GitHub-to-deploy flow; pick Fly.io for regional placement and protocol flexibility.
