Fly.io vs Koyeb
Koyeb is the closest like-for-like to Fly.io: serverless containers deployed across 25–30+ regions with a global edge, at almost identical prices. If the reason you're on Fly is the global reach, Koyeb is the one direct swap — but its 2026 acquisition changed the story.
The short version
Fly and Koyeb solve the same problem — run containers close to users, worldwide — and price it within a cent of each other. Koyeb is simpler to deploy to (a fully automated serverless experience) and adds native GPU instances; Fly gives more granular machine placement and control across a wider region list. The catch: Koyeb was acquired by Mistral AI in early 2026, which closed its free Starter tier to new users and is steering the roadmap toward AI inference and enterprise GPU rather than general web hosting.
How they compare
| Fly.io | Koyeb | |
|---|---|---|
| Model | Micro-VMs, machine control | Serverless containers, autoscaled |
| Global edge | 30+ regions (widest) | 25–30+ regions |
| Deploy experience | Machine-level control | Fully automated serverless |
| GPUs | Yes | Native GPU instances |
| Price (1 vCPU / 1 GB) | ~$10.70/mo | ~$10.71/mo |
| Free tier | Trial only | Starter closed to new users |
| Ownership | Independent | Acquired by Mistral AI (2026) |
| Roadmap focus | General app hosting | Shifting to AI inference / GPU |
When Koyeb wins
- You want Fly's global reach with less configuration — Koyeb's serverless model has more done for you.
- You need native GPU instances for ML/AI workloads alongside your web services.
- You're comfortable on an AI-focused platform and the Mistral direction fits where you're heading.
When to stay on Fly.io (or pick something else)
- You want granular machine placement and control — Fly exposes more of the machine.
- You're wary of the Mistral acquisition and the closed free tier — the platform's priorities are moving toward AI, not general hosting.
- You'd actually prefer predictable managed hosting over any edge platform — then look at Render or DigitalOcean instead.
Migration effort
Low for the app. Both run standard containers with a global edge, so redeploying your image on Koyeb is mostly build + env configuration, and you keep a similar multi-region posture. Move databases and volumes as a separate step, re-map secrets, and re-point DNS. Given Koyeb's roadmap shift, weigh whether a general-hosting platform is the safer long-term home before committing. To keep the build+deploy reproducible across whichever host you land on, run it in CI — Buddy builds from your repo and deploys anywhere.
