Lightpanda is an open-source project offering a lightweight alternative to traditional headless browsers, designed for automation and infrastructure. It reportedly runs automation tasks up to nine times faster than Chrome while using about sixteen times less memory.

Benchmarks were conducted on 933 real-world web pages on an AWS EC2 instance, showing Lightpanda using approximately 215 MB for 25 concurrent jobs compared to Chrome's 2 GB. The browser supports the Chrome DevTools Protocol, enabling easy integration with existing automation tools such as Puppeteer and Playwright. Lightpanda is licensed under AGPL-3.0 and its source code is hosted on GitHub.
