BrowserSkill

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.

Fast Browser Use is a local-first browser automation engine and agent skill for Claude Code, Codex, Cursor, and Python workflows. It runs Qwen3.5 models locally through MLX or PyTorch on Apple Silicon, CUDA GPUs, or CPUs, without cloud inference. The engine scans the rendered page for visible, interactable controls and converts them into bounded action candidates such as click, select, type, and done. It maps those candidates to single vocabulary tokens, scores them with one forward pass, and dispatches the selected browser action instead of generating CSS selectors, XPath expressions, or Playwright code. Text generation is used specifically for typing into fields, while structural actions use discrete logits scoring. The runtime also includes page-settling waits, visibility and occlusion checks, DOM-freshness checks, read-only protection, immutable execution traces, and external URL, title, and text assertions for outcome verification. The project provides a command-line interface, a Python API, and installable agent-skill integration, using Playwright Chromium for browser execution. It supports offline model operation after local weights are downloaded and is released under the MIT License.

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.

Agent Skills is a curated skill registry and npm-based CLI for extending AI coding agents such as Claude Code, Cursor, Copilot, and Antigravity with packaged instructions, templates, and reference files. The CLI fetches a catalog, lets users search and select skills, caches downloads locally, and installs them to selected agents by copying or symlinking them at global or project scope; it also supports updating, removing, auditing, and managing cached skills. The repository describes the catalog as an open-source, human-curated library with CI static analysis, content hashing, lockfiles, path isolation, symlink guards, sanitization, audit logging, and Snyk Agent Scan checks. It also includes an MCP server that exposes progressive-disclosure tools for listing, searching, reading, and fetching skill files. The CLI source is MIT-licensed; maintainer-authored skills are generally CC BY 4.0, while third-party skills retain their own licenses.
