blitz.cloud vs Fly.io: free hosting, EU regions and Docker compared
Fly.io against blitz.cloud on free tier versus trial, EU regions, Docker deploys, managed Postgres and certificates, with sources checked 14 September 2026.
Fly.io is the better choice when you need your containers in many regions close to users, arm64 or fine-grained control over machines, and you're happy to pay per use from the start. blitz.cloud fits when you want to host containers and a database for free in Germany without a credit card. Fly.io has no free tier: the trial ends after 2 machine hours or 7 days.

| Git push deploys | Not yet, planned | No built-in, GitHub Actions instead |
| Managed databases | PostgreSQL 17, MariaDB 11.4, Redis (Valkey 8), with nightly backups | Managed Postgres from $38 a month |
| Custom domains and HTTPS | HTTPS on your blitz.cloud subdomains. Custom domains not yet | First 10 certificates per organisation free, then $0.10 a month each |
Where Fly.io is the better choice
Fly.io runs your container in the regions you choose, and moving it closer to users is a command. If latency outside Europe matters, a single German data centre can't compete. You get direct control over machines, volumes and networking through flyctl, with private images and a mature CLI workflow.
Custom domains and certificates work now. The pay-per-use model gets cheap at small sizes once you're paying anyway, and it scales well past what a free plan offers.
Where blitz.cloud fits better
- You want to run something without entering a card, and keep it running after a week.
- You want a database included. A managed Postgres on Fly.io starts at $38 a month; on blitz.cloud one database is part of the free plan.
- You'd rather click through a dashboard than learn a CLI, or install a store app like Uptime Kuma or Linkding in a few clicks.
- A German operator and German data centre matter more to you than a choice of regions.
Moving from Fly.io to blitz.cloud
Fly.io apps already run from images, so the move is mostly about the registry and the user. Push the image to Docker Hub as a public amd64 image, make sure it runs without root on a port such as 8080, and deploy it. Volumes don't copy over automatically; move the data yourself. See deploy a Docker image.
