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
Stagehand
Pros
- + MIT-licensed SDK runs locally against any Chromium browser; in my test the act() call re-resolved after I rewrote a login button's classes and wrappers, while my hand-written Playwright selector broke
- + extract() returns schema-validated typed data (pydantic/Zod/struct) — pulling an invoice table into typed fields removed the JSON cleanup step entirely
- + observe() hands back real selectors, so I filled login credentials with ordinary Playwright calls and the secrets never reached the model
- + Full TypeScript, Python and Go support from one monorepo, with deep locators that reached nested iframes and a closed shadow DOM in my runs
- + Token cost per action is a fraction of screenshot-driven agents I have tested, because page context is a trimmed accessibility tree rather than images
Cons
- - Every act/extract/observe call is an LLM round trip — my ten-step workflow ran noticeably slower than the equivalent pure Playwright script
- - Code-only: no recorder or visual builder, so non-programmers cannot build or maintain automations
- - Anti-bot features (stealth, residential proxies, verified sessions) live in paid Browserbase plans, not the free SDK
- - Pages with canvas-rendered or heavily obfuscated UIs leave the accessibility tree thin and the AI primitives degrade
- - v4 is still moving fast; I pin versions because major upgrades have meant migration work
