Self-hosted persistent cloud dev boxes for coding agents. The composition root: wires the compute providers into the control plane.

The portable control plane: Hono + Drizzle/SQLite + SSE + in-process jobs, with the web build bundled in.

Azure compute provider — plain fetch against the ARM REST API, no vendor SDK.

Frozen v0 contract every Rocky Surf compute provider implements. Types and pure helpers — zero runtime dependencies.

Hetzner Cloud compute provider — plain fetch against the public API.

DigitalOcean compute provider — plain fetch against the public API, shipped as a self-contained personal provider.

AWS EC2 compute provider — plain RunInstances, no CloudFormation.

Google Compute Engine provider — plain fetch against the REST API, Application Default Credentials for auth.

SDK conformance checks every compute provider runs against itself. Test-only; never a runtime dependency.
