Alternatives to Fly.io
Run containers close to users worldwide
Fly.io ranks #12 of 12 in Cloud PaaS, with an Alt Score of 68. It is proprietary and available on the web. 10 of 10 checklist rows are verified against a public source.
Developers and teams who want to deploy full-stack apps, APIs, and databases without managing servers or complex cloud infrastructure. Well suited for workloads that need to run close to users worldwide, including AI agents and sandboxed/untrusted code execution.
App and database hosting that runs in 30+ regions globally, deployed straight from a Dockerfile or common framework (Rails, Phoenix, Django, Node, Laravel, .NET) without extra config. Includes private networking, built-in TLS, persistent volumes, and managed Postgres. Machines can scale to zero or fork instantly to handle bursts, so you pay mainly for active compute.
Fly.io packages your app into Fly Machines — fast-booting, hardware-virtualized micro-VMs (KVM-based, not just containers) — and places them in the regions you choose. A global Anycast network and built-in proxy route each request to the nearest running machine, and machines can start, stop, or scale automatically based on traffic.
