Lightpanda

Lightpanda is a headless browser engine written in Zig that executes web automation, crawling, and AI agent tasks without graphical rendering.

Lightpanda provides a web browser engine built from scratch in Zig, designed specifically for automation and AI agents rather than human interaction. It omits graphical rendering to focus entirely on JavaScript execution, which enables significantly lower memory consumption and faster performance compared to standard browser engines. The platform integrates with common automation tools like Puppeteer and Playwright, allowing users to maintain existing workflows while gaining efficiency. It isolates browsing states to prevent security risks associated with shared cookies and sessions. This tool targets developers and businesses needing scalable, high-volume web scraping or automated navigation.
