Freestyle is the infrastructure for code you didn't write — VMs and Git for AI agents. The platform provides Linux microVMs that boot in under 600ms with live-fork, pause-resume, and persistent snapshots; a multi-tenant Git service with branchable filesystems, GitHub Sync, full-text search, and webhook triggers; an Execute (Serverless Runs) API for ephemeral JavaScript/TypeScript code; a Web Deployments API for hosted Node.js apps and static sites; Cron schedules; custom Domains with wildcard SSL; an Identity service for scoped per-user and per-agent access tokens; and Observability logs. Freestyle is a direct sandbox option for AI app builders, background agents, code review bots, and long-running assistants — a usage-priced alternative to running Anthropic's hosted Code Execution tool or building bespoke microVM infrastructure on Firecracker, Modal, or E2B.

## Use cases (10)

- **AI app builders (Lovable, Bolt, V0 style) provisioning a sandbox VM per project with cloned source, dev servers, and *.style.dev preview domains**
- **Background agents (Devin, Cursor Agent style) forking a base VM into parallel workers — one builds the API, one builds the UI, one writes tests**
- **Code review bots (CodeRabbit, Greptile style) cloning a repo at a PR SHA, running lint/test, and posting a Claude-generated review**
- **Long-running AI assistants (Claude, OpenClaw, Cowork style) using a persistent VM with 60s idle pause to keep per-user state at $0 cost between turns**

- **Multi-tenant SaaS where each end user gets their own Freestyle Git repo and isolated VM**
- **Reinforcement learning on microVMs — fan out, train, fold in**
- **Deep-research agents that spawn, suspend on idle, and resume on event**
- **Hosted code playgrounds for educational and developer-tool products**
