Building Gnosis: A Multi-Agent Terminal with a 3D Office UI

I spent my summer building Gnosis, a local-first, open-source terminal coding agent designed around one idea: make multi-agent work easier to see and understand.

Instead of an endless stream of terminal output, Gnosis puts agents inside an interactive Three.js office, where their location reflects what they are actually doing.

Architecture

Gnosis uses a TypeScript backend for agent execution, tools, processes, and session state, with React + Three.js rendering everything in real time.
