AutoGen alternatives
Microsoft's AutoGen is in maintenance mode: its README says no new features will be added and directs new users to Microsoft Agent Framework. This page lists where existing AutoGen users and people evaluating it can go instead. Data as of 2026-09-30.
- Microsoft Agent Framework: The successor Microsoft recommends, with an official migration guide from AutoGen, group chat and Magentic orchestrations on a workflow layer, and checkpoints. See Microsoft Agent Framework vs AutoGen. (comparison)
- AG2: The community project that diverged from AutoGen in November 2024.
ag2-classickeeps the 0.2-styleautogenAPI;ag21.x is a new API. See AG2 vs AutoGen. (comparison) - AgentScope: Actively released Apache-2.0 framework with a permission system, sandboxed workspaces and MCP, A2A and AG-UI evidence; its team pipeline is leader-and-members rather than shared group chat. See AgentScope vs AutoGen. (comparison)
- LangGraph: If you want durable, resumable workflows, which AutoGen's record lists as something you must build yourself: checkpoints at every step and interrupts.
- CrewAI: If you used AutoGen for role-based teams: crews with roles and tasks, sequential or manager-led.
- CAMEL: For research on agent societies and role-playing dialogues, the use CAMEL started from, with a Workforce for task splitting.
