About Browser Use
Browser Use is an open source Python library and hosted platform that enables AI agents to control web browsers programmatically. It lives in the AI agent and browser automation ecosystem, built on Playwright and designed to let LLMs interact with websites as a human would—clicking, filling forms, solving CAPTCHAs, and navigating dynamic interfaces. The project provides three deployment paths: a fully hosted cloud service, a command line interface for existing agents, and a local Python library for custom integrations.

About WebAI2API
WebAI2API is a Node.js service that turns browser based AI sites — LMArena, Google Gemini, ChatGPT, DeepSeek, Sora, Google Flow and others — into a single OpenAI compatible HTTP API by driving a real Camoufox (Playwright) browser, built for developers and small teams who want programmatic access to those web interfaces without official API keys.
