Servo vs. Ladybird: A Battle of New Browser Engines

This article compares Servo and Ladybird, two projects aiming to revolutionize the browser engine landscape. Servo, initially backed by Mozilla, transitioned to the Linux Foundation due to funding issues and is now developed by Igalia with an undisclosed but significant funding source. Ladybird, started by Andreas Kling, relies on Patreon, GitHub sponsorships, and ad revenue, and has grown into an independent project with 7 full-time engineers, boasting substantial donations. In web standards compliance tests, Ladybird slightly edges out Servo, although Servo excels in CSS tests. Performance-wise, Servo significantly outperforms Ladybird, but both lag behind mainstream browsers. Both are open-source, but target different audiences and development models; Servo emphasizes embeddability, while Ladybird focuses on the browser itself.
