Sandboxing at Scale
Meet Fly Machines
Full Linux micro-VMs running on our metal, built from your own containers with a single command or API call.
Launch Instantly Fly Machines boot in around 300ms, fast enough to start in response to HTTP requests.
Clone Globally Use machines as templates to place your app in any region we serve.
Scale to Zero Pause machines when they’re not in use, paying only for machines that actually run.
Zero-Config Secure Networking Machines automatically connect to our global Anycast network and to IPv6 private networks.
We’ve got you covered
Enterprise-Ready Security
Apps running on Fly Machines have KVM hardware isolation, built on a memory-safe stack and running directly on our metal.
- Single Sign-On and MFA
- Secure-by-default private networking
- Memory-safe Rust and Go stack
- E2EE with A-grade TLS and WireGuard
- SOC2 attested
No Poster Board Necessary
Globally Distributed Databases Without the Science Project
Fly Anycast HTTP lets apps control routing, enabling single-writer multi-reader clusters for super-fast reads.
Fast nVME Storage
Create Fly Volumes from 1 to 500 gigabytes with a single command; they show up as directories in your VMs, use them however you like.
Automated Backups
Fly Volumes are snapshotted to off-network durable encrypted storage, no extra config required.
Postgres Cluster Management
Automatic leader election, fail-over, and member management, built on standard Postgres tooling.
Use our automated Postgres, or bring your own database, like CockroachDB or Mongo.
Comfort Zone Approved
Use the Tech You Love
Build with your favorite framework. No Dockerfile? No problem: our CLI generates containers for most popular frameworks, including Rails, Phoenix, Django, Node, Laravel, and .NET.
