A minimal autonomous agent runtime in Go. One ReAct loop, a small supply chain, and sandboxing by default in serve mode.
AI & Systems Research Lab
Open research.
Engineered infrastructure.
We build autonomous agents and fast, minimal systems — and publish what we learn.
20+ Open-Source Projects
Minimal dependencies
MIT Licensed
01 / Research Ideas tested in working systems.
02 / Engineering Small dependencies. Clear architecture.
03 / Open source Built to inspect, adapt, and extend.
Built at 21no.de
Research, made tangible.
Independent tools. Shared principles: minimal dependencies, inspectable architecture, and performance that matters.
Multi-Agent
Kai
