About

We run app servers and databases close to end users. Developers deploy their apps to Fly.io (it's about the simplest place to deploy a Docker Image) and use our CLI to launch instances in regions that are most important for their application.

Fly.io is a platform that lets developers run full-stack apps close to users by provisioning hardware-virtualized containers (Machines) and sandboxes. It enables fast deployment, private networking, and distributed compute across multiple regions with support for popular frameworks and databases.

Fly.io provides Machines, which are hardware-virtualized containers that deploy apps quickly, run only when needed, and can scale to many instances. It includes sandboxes for running AI-generated code with instant spin-up, private networking per sandbox, granular routing, end-to-end encryption, fast local NVMe storage and durable global object storage, and the ability to deploy in multiple regions with sub-100ms latency. The platform supports popular frameworks (Rails, Phoenix, Django, Node, Laravel, .NET) without requiring Dockerfiles, and offers built-in VMs, persistence options, and the ability to run distributed systems (e.g., CockroachDB, globally distributed Postgres) with zero Terraform configuration. Additional enterprise features include SOC 2 attestation, SSO, and priority support. Pricing emphasizes usage-based billing with optional reservations and a calculator for cost estimates.

Who it’s for: Developers and engineering teams building web applications and services who want to deploy and run code near users with distributed, private networking and scalable infrastructure.
