Stagehand
Leading#3 in Open sourcehigh confidence
Playwright-based framework (~24k★) exposing structured act/extract/observe actions — deterministic where possible, AI only when needed.Our read
Why it ranks #3
~23.6k GitHub stars and repeated top-three placement in 2026 framework comparisons establish Stagehand as the leading hybrid alternative: deterministic Playwright/CDP code where possible, AI actions where needed.Here is the catch
TypeScript-first approach is less convenient for Python teams
still requires an LLM and browser infrastructure in production
smaller ecosystem than Playwright or Browser Use
Does this well
better control and repeatability than fully autonomous agents
caching can reduce model calls on stable repeated workflows
fits naturally into TypeScript browser-automation projects

The rest of the Open source column.- 1Browser UseThe recognized leader for AI browser agents (~107k★, ~89% WebVoyager): gives the LLM full control of the browser through an agent loop — the default for building custom browser agents.
- 2PlaywrightMicrosoft's foundational browser-automation framework (~93k★) — the deterministic substrate many AI agents (Stagehand, Skyvern) build on; the de-facto standard for scripted control and E2E testing.
- 4SkyvernVision + LLM open-source agent (~23k★) resilient to layout changes; leads on form-filling (~85.85% WebVoyager).
- 5NanobrowserOpen-source Chrome extension (~13.5k★) for multi-agent web automation, running on your own LLM API keys as a free OpenAI-Operator alternative.
- 6Steel BrowserOpen-source browser API purpose-built for AI agents (~7.4k★): a self-hostable headless-browser backend for running web automations at scale.
- 7BrowserableSmaller but notable open-source library and API (~1.2k★) for building AI browser agents and automations; self-hostable.
