Render and Fly.io are the two most-loved successors to Heroku — but they took opposite bets. Render bet on simplicity: git push, fixed prices, a real free tier. Fly.io bet on power: run your containers at the edge in 30+ regions, billed per second.
This comparison is really about who should pay for convenience. Compare them on the dimensions that decide your actual deployment experience.
| Render | Fly.io | |
|---|---|---|
| Starting price | Free tier (sleeps when idle) | Pay-as-you-go, ~$2/mo for a small app |
| Always-on web service | $7/mo Starter | ~$2–5/mo per Machine, scales to zero |
| Managed Postgres | From $7/mo, same dashboard | Fly Postgres from ~$38/mo — pricey |
| Free tier | Yes — web services, Postgres, static sites | No ongoing free tier (short trial only) |
| Regions | Limited list (US, EU, Singapore) | 30+ regions with Anycast routing |
| Deploy model | Git push → build and deploy | Docker containers via CLI (flyctl) |
| Best for | Side projects and teams that want predictable bills | Global apps and power users comfortable with a CLI |

Try Fly.io →Render is the sane default: a real free tier and $7 managed Postgres beat Fly.io on budgeting. Fly.io wins when your users are everywhere and you want Docker-native control at the edge for a few dollars a month. Prototypes start on Render; global production leans Fly.io.
Yes — free web services sleep after 15 minutes of inactivity, so cold starts are real. Fine for demos and portfolios, not for production.
Machines bill per second and scale to zero, which is cheap for spiky workloads. But every component — Machines, volumes, IPs, egress — is metered separately, so the bill takes a spreadsheet to predict.
Render for speed: git-push deploy with a real free tier gets your AI prototype live in minutes. Fly.io when the app needs to sit close to users globally and you're comfortable with a CLI-driven workflow.
