Freestyle

Freestyle is infrastructure for the world where most code is written by agents rather than humans. It gives an AI agent its own real Linux VM with a Git-backed filesystem, so every file edit produces a commit on a branch the human (or another agent) can review. The platform is API-first: spin up a VM in a couple of seconds, mount a repository, give an agent shell access, then snapshot, fork, or destroy the environment when the task is done. Because each agent works on a real branch, you get an auditable history of what the model did, can roll back any change with a normal git revert, and can run parallel agents on the same starting commit without them stomping on each other. Freestyle also exposes JavaScript sandboxes for code interpreter use cases and integrates cleanly with frameworks like Mastra, Inngest AgentKit, and the OpenAI Agents SDK. Common workloads include autonomous coding agents, deep research scratchpads, untrusted code execution from end users, and CI-like reproducible task runners. Pricing is usage-based on VM minutes plus storage, with a generous free tier for prototyping. For teams who have outgrown ephemeral REPL-style sandboxes and need real Linux semantics with version control, Freestyle is one of the cleanest options on the market.
