AutoGen
Pros
- + GroupChat and team patterns make multi-agent role decomposition genuinely practical — in my trial a three-agent setup handled research, drafting and review as separate conversational turns
- + 0.4's event-driven Core layer with typed async messages gave me clean separation between agent logic and transport when I split agents across processes
- + Tool execution inside AssistantAgent (no user-proxy registration) removed the 0.2 boilerplate I used to copy into every project
- + Human-in-the-loop checkpoints are a first-class concept, so approval gates don't need custom plumbing
- + Free and open source with a published migration path to Microsoft Agent Framework — the exit is documented rather than improvised
Cons
- - Maintenance mode since October 2, 2025: no new features, community-managed, with Microsoft pointing new users to Microsoft Agent Framework
- - The 0.2→0.4 rewrite is a breaking change, and the old `pyautogen` PyPI package is no longer Microsoft-controlled — supply-chain risk for unmigrated projects
- - Three 0.2 features (model client cost tracking, teachable agents, RAG agents) were listed as future work in the migration guide — parity is not automatic
- - Multi-agent conversations multiply model spend; my five-round three-agent run cost about 10x a single-agent loop on the same task
- - No built-in provenance ledger for which agent's output shaped the final answer in a group chat
CrewAI
Pros
- + Role/goal/backstory abstraction produced clearly differentiated agent behaviour from one underlying model in my three-agent crew test
- + Export-as-MCP-server worked as documented — the crew came up as a tool server a coding agent could call
- + Tracing, OpenTelemetry export and Slack-based human-in-the-loop pauses made a recurring workflow operable
- + The open-source framework installs from PyPI and runs anywhere Python runs; no platform commitment required
- + Studio's AI copilot generated a working workflow skeleton from a plain-language description
Cons
- - Free tier is 50 workflow executions/month — a demo allowance, not a working quota
- - The $25/month Professional tier shown on archived pricing pages is gone; after free there is only a sales conversation
- - Token burn surprised me: a reviewer loop on a three-agent crew cost far more than a single-agent equivalent
- - Hierarchical delegation occasionally looped or duplicated work until I tightened task boundaries
- - SSO, RBAC and PII redaction are Enterprise-gated, so the free tier is unusable for sensitive data
