Lightpanda Browser is an open-source browser optimized for headless usage, supporting partial Web APIs and Playwright and Puppeteer compatibility through CDP. It offers fast web automation for AI agents, LLM training, scraping, and testing with ultra-low memory footprint and exceptional speed, outperforming Chrome by 9x in memory consumption and 11x in execution. The browser can be easily installed from nightly builds for Linux x86_64 and MacOS aarch64. Lightpanda is built from scratch with Zig, focusing on performance without graphical rendering, and is still in the Beta stage with ongoing development to improve coverage of Web APIs and Javascript support.
