Cap’n Proto is an insanely fast data interchange format and capability-based RPC system. Think JSON, except binary. Or think Protocol Buffers, except faster.
Compile Cloudflare Workers to Cap'n Proto and deliver them as minimalist Docker images.
Workerd-based hypervisor with a declarative Cap'n Proto manifest. Substrate-level identity, audit, and per-bundle credential scoping. Today's primary application: hosting MCP servers behind one HTTP face.
A zero-copy distributed runtime built on SharedArrayBuffer. Go kernel orchestrates Rust WASM compute modules with atomic epoch signaling. No wasm-bindgen, no serialization overhead — just shared memory and 60FPS+ rendering. BSL-1.1 licensed.
Self-sovereign agent identity. Cap'n Proto schemas, CF Worker authority, ley-line-sign Wasm.
