The closest alternatives to Fly.io are AWS Amplify Hosting, Cloudflare Workers & Pages, Coolify and Deno Deploy, with 4 more below. Each shares a comparison category with it, so every rationale here names both tools' real values. Fly.io is 10th of 13 on Free tier (2), usually where a switch starts.
Why do people look for Fly.io alternatives?
- Most people searching for Fly.io alternatives are not shopping, they already run it and something has stopped fitting.
- That something is usually a specific number rather than a feeling.
- This page starts from the fields where Fly.io genuinely trails the rosters it appears in, and only then covers the reasons that never show up in a table.
The measured reasons.
- Free tier, 2, 10th of 13. Cloudflare Workers & Pages
records 5.
- Any one of those is enough on its own if you sized your architecture around it.
- None of them is enough if you didn't, which is why the list is short and specific rather than a general case against Fly.io.
The reasons that never make it into a table.
- A price rise after a funding round.
- A licence change that turns a self-host into a subscription.
- A region you now need and they do not have.
- An acquisition.
- A support experience that quietly degrades.
- None of those are fields, and all of them move teams, which is why every entry below links back to Vercel alternatives, where the full field set and its sources live.
- The ones we catch get logged on the Fly.io timeline.
How the shortlist is ordered.
- Every tool below shares at least one comparison category with Fly.io, sorted by how many categories the two overlap in.
- There is no editorial ranking, no sponsorship and no affiliate link, the order is the overlap count.
- The rationale under each is generated from the two tools' own cells, so it names real values rather than adjectives.
1.
AWS Amplify Hosting

- Best for apps whose data already lives in AWS, especially in Sydney.

How this list was built
There is no editorial ranking on this page and no sponsorship behind it. The order is mechanical: every tool that shares a comparison category with Fly.io, sorted by how many categories the two overlap in. A tool that meets Fly.io in three rosters sits above one that meets it in a single roster, because more overlap means the comparison is more like-for-like.
The rationale under each entry is composed from the two tools' own cells. Where they differ on a field we score, the sentence names both values and the unit. Where they don't differ, it says so instead of manufacturing a distinction, which is why some entries are short.
Values, sources and verification dates all live on the category tables: Vercel alternatives. If a figure here disagrees with a vendor's current pricing page, the vendor is right and we are stale.
Still deciding whether to move at all? The Fly.io profile has the when-to-use and when-not-to-use blocks, and the Fly.io timeline has the dated changes that usually trigger a migration.
