Best for small servers in many regions, billed by the second
Fly.io runs virtual machines in 18 regions, billed by the second, from $2.19 a month. There's no free plan, the trial is $1 for 7 days, and the vendor's own example of a small web app with Postgres comes to about $44 a month.
Who Fly.io is for
- Fits if you want machines near users in several regions and are fine on the command line
- Works for apps that stop when idle and pay by the second
Who Fly.io is not for
- Skip it if you want a free plan, as the trial is $1 for 7 days
- Not for you if you don't like a command line
- Pricey if you add a database: Managed Postgres starts at $38 a month
- Watch out: the prices quoted are for Ashburn and Secaucus, the cheapest regions, and a dedicated IPv4 is $2 a month
- Watch out: data out costs $0.02 per GB in North America and Europe and $0.12 in Africa and India

Keep Fly.io, or make your own?
Keep it
To replace Fly.io you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.
It costs $26.28 a year.
What you could not
- An AI agent, with the models and the safeguards behind it.
- Databases with views, filters and links between them.
- It plugs into other products, GitHub, Slack and Tigris among them, and has an API.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Fly.io’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
