An open, 12MB runtime for fast AI agents

San is an open-source ~12MB terminal runtime for AI agents. Plug in any model, any search backend, and switchable personas; it learns from your work into durable memory and skills. Fast and lean — ~0.01s cold start — and built to be an open, reusable harness you can shape.
Hi PH 👋
I kept rebuilding the same layer for every agent I made — the harness around the model. So we built one worth keeping and opened it up.
San is one ~12MB Go binary with ~0.01s cold start — small enough to run anywhere, from your laptop to a CI step, a container, or an edge device.
It's flexible by design: plug in any model and search backend, switch personas to keep each agent's context lean. It learns as you work, turning recent sessions into durable memory and reusable skills. And it plugs into what you already use — skills, subagents, plugins & MCP run unmodified.
It's an open, fast harness, made to be built on. Apache-2.0, and we'd love to build it out with you.
