Open-Source AI Agents Directory
Find open-source AI agents you can run yourself: coding, research, browser and workflow agents, plus frameworks for building your own. Compare them by GitHub stars, licence and recent activity, see what each agent can touch on your machine, and read the dated scan report where one has run.
Coding agents, research agents, browser agents, workflow builders and agent frameworks, all open source.
