Skyvern
Leading#4 in Open sourcehigh confidence
Vision + LLM open-source agent (~23k★) resilient to layout changes; leads on form-filling (~85.85% WebVoyager).Our read
Why it ranks #4
~22.6k GitHub stars plus an independently cited ~85.8% WebVoyager result make Skyvern a top-four framework, especially for visual form-filling and workflows that must survive layout changes.Here is the catch
vision and model calls add latency and variable cost
self-hosting is heavier than a simple browser library
AGPL license is more restrictive for proprietary deployments
Does this well
resilient on unfamiliar pages without hand-written selectors
particularly strong for forms and cross-site workflows
offers both developer SDKs and a no-code builder

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.
- 3StagehandPlaywright-based framework (~24k★) exposing structured act/extract/observe actions — deterministic where possible, AI only when needed.
- 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.
