Best open source AI agents and agent frameworks
The best open source AI agent platforms you can self-host are Langflow, RAGFlow and OpenHands. Langflow leads with 156,084 GitHub stars.
Candidates: the 13 AI tools, low-code, automation and API apps whose own description or topics mention AI agents, agentic workflows or multi-agent systems.
Apps are included only when their own description or topics talk about AI agents (agents, agentic, multi-agent or autonomous agents) and they are AI tools, low-code, automation or API platforms. Agent features vary a lot, from visual agent builders to coding agents, so check each project's documentation.
