BrowserOS

Browser Use is an AI browser-automation framework and hosted service for assigning web tasks to agents. Its agents operate websites through a browser by opening pages, clicking controls, entering text, filling forms, and extracting structured data. The project provides a Python library for embedding browser agents in applications, a CLI for agent-driven one-off tasks, and a Browser Use Cloud API with hosted agents and managed browser infrastructure. The library supports different LLM providers, custom tools, structured output, reusable browser profiles, and parallel or scheduled automation. The open-source library is free to use and licensed under the MIT License; the hosted service adds scalable browser infrastructure, proxy rotation, stealth browser fingerprinting, CAPTCHA handling, persistent storage, and integrations.

Browser Use Pi is a TypeScript web agent built on Pi Mono. It combines a persistent V8 REPL with raw Chrome DevTools Protocol control: the agent writes JavaScript, uses accessibility-tree data and screenshots, and builds browser helpers as needed. It supports persistent sessions, saved logins, workspaces, streaming, hooks, typed results, follow-up tasks, and cloud browsers or a user's own Chrome; runs can be limited by steps, time, or cost, with partial work retained. Interaction highlights, recordings, and GIF exports can show the agent's work. It is distributed as the @browser_use/pi package for Node 22.19+ or Bun 1.3.14+, and its quickstart uses Browser Use Cloud without requiring a local Chrome installation.

ego lite is a macOS browser from Citro Labs designed for AI-agent browser automation alongside a user's normal browsing. It gives each agent or task an isolated Space within the same browser, allowing multiple tasks to run in parallel without taking over the user's tabs; users can observe, take over, or stop an agent's Space. Through the ego-browser skill, agents such as Claude Code, Codex, Cursor, or custom agents can call in-page JavaScript tools including snapshot, fill, click, wait, navigate, and capture; an agent can compose several operations into one JavaScript execution rather than repeatedly issuing CLI commands. During setup, optional Chrome-data migration can transfer existing logins, cookies, extensions, and bookmarks, while browsing data remains on the user's device. The browser is distributed as a separate free download, the repository is MIT-licensed, and Windows and Linux support are listed as planned.

BrowserSkill is an open-source browser-automation bridge for AI agents, consisting of the `bsk` CLI and daemon plus a Chrome or Microsoft Edge extension. An agent sends browser tasks through the CLI; the local daemon routes them over WebSocket to the extension, which performs actions in a separate visible Agent Window. Agents can use existing browser login state, borrow an already open tab only with explicit approval, and request human intervention for captchas, confirmations, or other user-only steps. It supports shell-capable agent harnesses, macOS, Linux, and Windows, and is distributed under the MIT license.
