Overview

The platform for devs who just want to ship. Powered by sandboxes that let you deploy any code with confidence. For builders who need compute that keeps up with their ideas, Fly Machines are hardware-virtualized containers that launch instantly and run only when you need them. Deploy an app in minutes or run untrusted code in isolated sandboxes. Spin up hardware-isolated sandboxes for running AI-generated code in complete safety. Every Sprite is a self-contained environment, ready for action in under a second. Checkpoint your entire environment, run anything, and restore if you break something. Pay only for actual CPU and memory consumption, down to the second.
