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 20 API contracts indexed on the APIs.io network, including Auth API, Certs API, Cron API, and 17 more. Tagged areas include Artificial Intelligence, Agents, Sandbox, VMs, and MicroVM.
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 45 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| ONVIF Video Analytics (video surveillance, edge cameras, computer vision) | undeclared | - | - | 1 |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards implemented 1
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
