OS1 (nokodo) is a full-stack AI-powered collaborative platform combining autonomous agents, deep research, real-time collaboration, and extensible tooling in a self-hostable workspace. The system features a modular architecture with FastAPI/Python backend, Svelte 5 frontend, and separate admin console, communicating via REST API, WebSocket, and Redis pub/sub. Core capabilities include AI agent construction with tool integration (web search, code execution, file operations), persistent memory system with vector search, real-time document editing, and comprehensive resource management (threads, notes, files, projects, calendars, reminders). The platform emphasizes extensibility through plugin systems for tools, filters, and hooks, with production-ready deployment via Docker Compose.
