Twenty open-source AI agent projects and agent-building frameworks, ranked by reported GitHub star count from live web research on 2026-08-28. Stars are approximate point-in-time figures reported by current web sources and can change quickly; the boundary between an "agent" and an "agent framework or platform" is fuzzy, so read the categories as a guide, not a taxonomy.
