Pros	Official, well-tested abstractions Same primitives as Claude Code Strong tool-use ergonomics TypeScript + Python SDKs	Reuses your logged-in Chrome state, so no API keys, OAuth or scraping needed Open-source (Apache-2.0) with a plugin registry and YAML/TS adapter system Also CLI-ifies Electron apps like Cursor, ChatGPT and Notion for agent control Record-and-replay turns real browser sessions into reusable CLI commands Ships skills/adapters for Claude and other local AI agents out of the box
Cons	Claude-only Newer than LangGraph/CrewAI	Early-stage solo-maintainer project with a thin English marketing site Requires a local daemon plus a Chrome extension — non-trivial setup Adapter coverage depends on the community; many sites still unsupported Tying agents to your live login carries real account-risk if scripts misbehave
