My honest take
My honest take: I'd lean Railway for most founders, but the gap is small enough that the second choice isn't wrong. Railway edges it at 84 vs 80 mostly because of ease of use (Railway scores 9/10 there). Fly.io still wins if your specific situation calls for run your app close to users worldwide. Either way you'll be fine. The expensive mistake is overthinking the decision.

Real-world scenarios
Which one wins in your specific situation.
- You're a solo founder shipping your first product: Railway is the cleaner choice. Less setup, fewer enterprise-only features locked behind upgrades, pricing that makes sense for one seat.
- You already use Fly.io and it's working: don't migrate. The score gap (4 points) doesn't justify the disruption. Migration costs are real · half a day to a weekend of work plus a week running both in parallel.
Stack fit
How each fits inside a founder stack.
A tool you can't integrate is a tool you'll replace in six months. Here's how each plays with the rest.
Fly.io
Fly.io fits cleanly in a stack with Next.js, Supabase, Stripe, Resend. If your stack already includes most of those, Fly.io integrates without friction.
Railway
Railway fits the same kind of stack. If your existing stack leans toward Next.js or Supabase or Stripe, Railway doesn't create integration debt either.
Final recommendation
For most founders, Railway. The gap is small enough that the other tool is still a respectable second choice if your situation calls for it. If you're already on Fly.io and it's working, don't migrate. The cost of switching is real and the gain is small.
Bottom line
Railway for most founders.
Railway edges it. Slight lead at 84 vs 80. Best for deploy anything with zero config. Go with Fly.io if you specifically need run your app close to users worldwide.
