The honest brief
Stagehand
Mixes deterministic code with natural-language act()/extract() — no all-or-nothing handoff to a black-box agent.
- CDP-native v3 driver, no Playwright lock-in
- Mix code and NL primitives
- TypeScript and Python SDKs
- Model-agnostic (OpenAI/Anthropic/Google)
- SDK, not a no-code tool
- Best paired with Browserbase cloud
- Reliability depends on model choice
- Newer than raw Playwright/Puppeteer
Tabstack
Mozilla-backed and escalates from cheap fetch to full automation only when a page demands it — paying for a browser only when you need one.
- Single API for extract, generate, and automate
- Markdown/JSON output tuned for LLM context
- Open-source engine (Pilo, Apache-2.0)
- Free tier with 10,000 credits
- Hosted service is proprietary (only the engine is OSS)
- Credit-based pricing can be hard to forecast
- Newer entrant vs. established browser-infra players
