About OpenAgent
OpenAgent is an open-source, self-hostable personal AI assistant that combines LLM access, a document-based RAG knowledge base, and agent loops for computer-use, browser-use, and coding tasks. It connects to multiple model providers and can browse the web, run shell commands, work with Word, Excel, and PowerPoint files, and use MCP-compatible tools.
It is distributed as a single binary with pre-built releases for Linux, macOS, and Windows on x86_64 and arm64, and can also run with Docker. Installed or container instances use http://localhost:14000; building from source requires Go 1.25.0+ and Node.js 20+ with Yarn 1.x.
