OpenAgent

OpenAgent is an open-source personal AI assistant platform that connects to over 30 model providers and deploys across messaging channels.

OpenAgent is an open-source, self-hosted personal AI assistant platform distributed as a single binary. It enables users to run intelligent agents that use tools, call APIs, and reason across multi-step workflows with persistent memory via Model Context Protocol (MCP). The platform provides a unified interface for more than 30 model providers, including OpenAI, Claude, Gemini, DeepSeek, Qwen, and Mistral. Users can upload documents, PDFs, and spreadsheets to build a semantic knowledge base backed by vector databases like Qdrant, Pinecone, Milvus, or PgVector. Built for developers and privacy-conscious builders, it deploys simultaneously to messaging channels such as Telegram, Discord, and WeCom.
