blitz.cloud vs Fly.io: price, EU regions and Docker compared
Fly.io against blitz.cloud on price, 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 the EU without a credit card. Fly.io has no free tier: the trial ends after 2 machine hours or 7 days.

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 data centre in the EU 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.
- You want every push to GitHub to go online without writing a CI workflow for it.
- A German operator and an EU 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. Push the image to Docker Hub as a public amd64 image, make sure it listens on a port such as 8080, and deploy it. Volumes don't copy over automatically; move the data yourself. See deploy a Docker image.
If the image is built from a GitHub repository, you can instead connect GitHub and let blitz.cloud build every push. The image can also stay on any public registry, such as ghcr.io, rather than Docker Hub. See deploy a GitHub project.
