Freestyle
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.
Freestyle publishes 11 APIs on the APIs.io network, including Auth API, Certs API, Cron API, and 8 more. Tagged areas include AI, Agents, Sandboxes, VMs, and MicroVMs.
The Freestyle catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Freestyle’s developer surface includes authentication, developer portal, documentation, getting-started guide, signup flow, pricing, engineering blog, and 43 more developer resources.
