Lightweight headless browser written from scratch for automation
What it is
A headless web browser built in Zig rather than forked from Chromium or WebKit, using far less memory and time per page than headless Chrome. It exposes a Chrome DevTools Protocol server and WebDriver BiDi so existing Puppeteer and Playwright scripts can connect to it, and can dump pages as HTML, markdown, PDF, or structured data from the command line. Developers running scrapers, crawlers, and AI agents use it to cut infrastructure costs, and a built-in agent mode drives the browser from plain-English instructions and exports replayable scripts.
