About

Lightpanda is an open source headless web browser designed specifically for AI systems and large-scale web automation workloads. Unlike traditional browsers such as Chrome or Firefox that are built primarily for human interaction and graphical rendering, Lightpanda is engineered from the ground up for machines and automated processes. It runs without a graphical interface and focuses only on the components required for programmatic web interaction, such as HTML parsing, DOM tree construction, and JavaScript execution. By eliminating visual rendering tasks like layout calculations, image loading, and pixel painting, the system dramatically reduces resource usage and improves performance for automation tasks. Lightpanda was built from scratch using the Zig programming language rather than modifying an existing browser engine, allowing it to be optimized for speed, reliability, and minimal memory consumption.

About

Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox. Test on Windows, Linux, and macOS, locally or on CI, headless or headed. Playwright waits for elements to be actionable prior to performing actions. It also has a rich set of introspection events. The combination of the two eliminates the need for artificial timeouts - the primary cause of flaky tests. Playwright assertions are created specifically for the dynamic web. Checks are automatically retried until the necessary conditions are met. Configure test retry strategy, capture execution trace, videos, screenshots to eliminate flakes. Browsers run web content belonging to different origins in different processes. Playwright is aligned with the modern browsers architecture and runs tests out-of-process. This makes Playwright free of the typical in-process test runner limitations.
