Our Analysis
If you run headless browsers for web scraping, testing, or AI agent browsing and Puppeteer/Playwright feel slow and memory-hungry, Lightpanda is a headless browser built from scratch in Zig specifically for speed. We're talking 10-50x faster than Chromium-based headless browsers for page loading and JavaScript execution, at a fraction of the memory. The target audience is anyone running browsers at scale: scraping pipelines, automated testing farms, AI agents that need to browse the web. When you're paying per minute of compute and per GB of RAM, a browser that uses 90% less of both changes your infrastructure costs dramatically. 25K+ stars, exploding growth (+2,295/wk). AGPL-3.0 license. They offer a cloud service alongside the open source browser. The catch: it's not a full browser. It doesn't render pixels — no screenshots, no visual testing. JavaScript support is growing but not at Chrome-level compatibility. Sites with complex JS frameworks may not work correctly yet. And AGPL means if you modify it and serve it to users, you must open source your changes.
