Lightpanda is an open-source headless browser built from scratch in Zig and optimized for AI agents, large-scale scraping, LLM training, and automated testing.

It executes JavaScript, supports key Web APIs, and exposes a Chrome DevTools Protocol server, making it compatible with tools like Playwright, Puppeteer, and chromedp. Benchmarks report around 9x lower memory usage and 11x faster execution than headless Chrome, with instant startup for cloud and container workloads.
