Overall Score
Based on our independent scoring across 6 dimensions, Railway scores 85/100 overall versus Fly.io's 84/100 — a 1-point margin. Railway leads on Performance in particular. That said, Fly.io may still be the right choice if the dimensions where it scores higher match your specific priorities — the radar chart above shows the full profile side by side.
Both Fly.io and Railway offer a free tier, so entry-level cost is not a differentiating factor. Compare the feature and usage limits of each free plan to see which gives you more headroom before a paid upgrade is needed.
Fly.io scores higher on Scalability — 90/100 versus 78/100 for Railway. If scalability is your primary decision criterion, Fly.io is the stronger choice in this head-to-head.
Switching between dev hosting tools is generally possible but involves migration effort: exporting your data or configuration from Fly.io, re-importing or reconfiguring in Railway, and updating any API integrations or environment variables in your codebase. The effort scales with how deeply embedded the tool is in your stack. Test Railway on a non-production project first before migrating.
Fly.io (84/100) is the better fit for teams who prioritise performance — its strongest dimension — and who want a free entry point. Railway (85/100) is the better fit for teams who prioritise developer ux and want a free entry point. If both dimensions matter equally, the overall score winner (Railway) is the safer default choice.
