Lightpanda · They are rebuilding the browser on the premise that nobody is looking at it — which is the cheapest, most measurable claim on the roster, and nobody has independently benchmarked it against headless Chrome.

A web browser written from scratch in Zig, on the assumption that the visitor is a machine. It throws away graphical composition entirely — no rendering for human eyes — so it starts in milliseconds on a fraction of the memory, and it speaks the Chrome DevTools Protocol so Playwright and Puppeteer code works against it unchanged. Open source, with a hosted cloud on top. Their own newer surfaces are Lightpanda Agent and PandaScript, native MCP, structured Markdown output, and request interception.
