About Freestyle

Freestyle builds the most powerful VMs for AI Agents. - **Instant Startup**: Freestyle VMs provision in milliseconds, with p99s under 400ms. - **Persistence**: Freestyle VMs can run forever, they can be hibernated with their exact memory in place and come back to life weeks later instantly, in that exact state. - **Powerful**: Freestyle VMs go up to 64GB of RAM for public tiers and much further for enterprise. Freestyle does high quality hardware virtualization supporting nested virtualization, FUSE, eBPF, full Linux networking and more. If it can run in an EC2, it can run in a Freestyle VM. - **Cheaply Snapshottable and Branchable**: Freestyle VMs are instantly and cheaply snapshottable (sub 1ms interruption, sub 50ms to snapshot ready). These snapshots can be used to create new VMs in the exact state of the original VM (memory and disk). This enables powerful workflows like branching, cloning, and rapid recovery from failures.
