AG2 (AutoGen v2)
The community AutoGen fork — 5K stars keeping the original multi-agent vision alive.
About
AG2 (4,992 GitHub stars, Apache-2.0) is the community fork of Microsoft AutoGen: when Microsoft moved AutoGen to maintenance mode, the community (as AG2 AI) forked it to continue the original multi-agent vision independently.
Actively maintained (pushed Oct 2026). For teams with existing AutoGen codebases who want continued feature development (rather than migrating to Microsoft Agent Framework), AG2 is the path. The fork is young — long-term viability depends on community momentum — but the maintenance is active.
What it can do
- • Community continuation of AutoGen\n• AgentChat multi-agent conversations\n• Code execution and tool use\n• Drop-in for AutoGen codebases\n• Independent feature development
Setup
- Install:
pip install ag2.\n2. Set your model API key.\n3. Use the familiar AutoGen AgentChat API — drop-in for most codebases.\nSee https://docs.ag2.ai for migration notes.
Prerequisites
Python ≥ 3.9; an LLM API key; (for migration) an existing AutoGen codebase.
Use cases

Trust score — 8/10
Scored 8/10 (verified tier). Apache-2.0, actively maintained with 34 releases, and the right answer for AutoGen codebases that want continued development. Docked two points: (1) young fork — long-term viability unproven; (2) competes with Microsoft's official successor. For AutoGen holdouts.
