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
Flowise
Pros
- + Node canvas gives LangChain-level control over retrieval, agents, and tools without writing code — my retrieval agent took one sitting
- + Self-host path is real: npm or Docker, minutes to localhost:3000, Apache 2.0 core license
- + Human-in-the-loop review nodes make the agents-propose-humans-release pattern easy to wire
- + Wide model and vector-store support (100+ LLMs, embeddings, vector DBs per the vendor) keeps you off proprietary lock-in
- + Evaluations, metrics, and run observability are built into the builder rather than bolted on
Cons
- - Node picker presumes you understand embeddings, chains, and retrieval strategies — beginners are lost quickly
- - Production self-host means doing your own persistence, secrets, queue/workers, and uptime — time not visible in the free price
- - Enterprise identity and permission features live under a commercial license inside the same repo
- - Cloud free tier (100 predictions/month) is too small to judge real performance
- - Fast-moving node surface and uneven community templates mean upgrades can break flows
