Playwright

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.

Puppeteer is a JavaScript library that provides a high-level API for controlling Chrome or Firefox through the DevTools Protocol or WebDriver BiDi. It runs browsers headlessly by default and can automate navigation, viewport settings, keyboard input, locating and interacting with page elements, and browser shutdown. The library can be used to render web content into PDFs; the video describes substantial memory usage and slow cold starts as drawbacks in that use case. The `puppeteer` package downloads a compatible browser during installation, while `puppeteer-core` provides the library without downloading Chrome.

jev-voice-browser is a Node application that controls a headed Chromium browser by voice or typed commands. It streams partial speech transcripts from the browser's Web Speech API to a Node server, which uses TypeSafe's Jev model to classify the intent, select a page element or site, extract candidate text and URL spans, determine whether the command is complete or addressed to the browser, and assess whether an action is destructive. Playwright then executes navigation, searches, typing, clicking, scrolling, history, and tab actions. The application sends the page URL, title, detected site, a compact snapshot of visible elements, and recent actions to Jev for each transcript update. Code—not the model—constructs URLs, copies text verbatim, and applies policy thresholds to decide whether to act, wait, ignore, request confirmation, or show numbered alternatives. Recent action context supports corrections such as reversing an action, rejecting a selected result, or choosing another candidate. It requires Node.js, Chrome or Edge for microphone input, Playwright's Chromium installation, and a TypeSafe API key. The server can launch a persistent-profile Chromium window or attach to an existing browser through CDP; it also supports headless operation and typed commands when no microphone is available.

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.
