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
Browserbase
Pros
- + Session replay, live viewing and logs turned a failing agent step into a diagnosable one — the debugging surface is the strongest I have used in this category
- + Attaching Playwright over CDP behaved like a local browser in my runs: real rendering, cookie persistence across requests
- + Stagehand (MIT, 25k+ stars) lets agents mix natural-language actions with ordinary Playwright code, and runs locally for free before you need hosted scale
- + Itemized public pricing with a real free tier to prototype on, including $5 in model tokens and 1,000 search/fetch calls
- + Identity features (auto captcha solving from Developer tier, Verified Sessions on Scale) address the part of browser automation that actually fails in production
Cons
- - Six separately metered line items — hours, proxy GB, search, fetch, agent runs, model tokens — so the plan price is a floor, not the bill
- - Proxy sessions carry a 1 MB minimum per session; high-volume tiny sessions pay for data they never moved (~$120 per 10,000 sessions at Developer proxy rates)
- - Stealth tiering is underspecified: public docs never define what 'Basic' excludes versus Advanced/Verified on Scale
- - Free tier is a demo — 1 browser hour/month and 15-minute session caps stopped my first long test exactly at the limit
- - No local-only or self-hosted option for the hosted stack; latency variance versus local browsers is inherent to the model
