Nanobot

Nanobot is an ultra-lightweight, open-source personal AI agent framework written in Python. It enables developers to build and deploy autonomous agents for chat applications, workflow automation, long-running tasks, and developer integrations. The framework supports multiple interfaces including a web UI, terminal, and integration with chat platforms. It provides built-in tools for memory management, supports the Model Context Protocol, and can handle multi-agent workflows. Nanobot is developed by HKUDS and released under the MIT license.

The framework emphasizes efficiency with compact code footprints, predictable token usage, and sensible context management. It supports long-horizon execution across many steps while maintaining coherent context. Nanobot is self-hosted, meaning developers run it on their own infrastructure rather than relying on external services. The tool is designed to be portable and embeddable, allowing integration into various business applications and daily workflows. Installation is available through multiple methods including shell scripts, PowerShell, PyPI, and direct source installation.
