What it is

An Electron desktop app that wraps terminal coding CLIs such as Claude Code, Codex, Gemini CLI, OpenCode and Copilot CLI, running each as a real pseudo-terminal session shown as an avatar on a 2D office floor. Agents get long-term markdown memory with semantic recall and a mailbox, while a coordinating agent routes work between them. It works with the subscriptions and API keys you already pay for, and can also run models locally via Ollama, LM Studio or vLLM. Developers who want several coding agents working in parallel on their own machine can use it to delegate and watch the work.
