Andreas Kling reported that the Ladybird browser successfully passed 90% of the tests from the web-platform-tests suite, which determine compatibility with the benchmark web platform. According to Apple's requirements, this milestone is enough to be considered an alternative browser engine for iOS. Ladybird has successfully completed 1,861,180 checks out of 2,033,861. In comparison, Chromium 139 passed 1,996,034 checks, Firefox 143 - 1,942,510, Safari 26.0 - 1,952,703, Servo - 1,672,466.
The web-platform-tests are formed as part of the Interop initiative, jointly promoted by Google, Mozilla, Apple, Microsoft, Bocoup, and Igalia, aimed at testing the level of implementation of web technologies in browsers and identifying discrepancies that affect the appearance and behavior when processing websites.
The Ladybird browser is being developed by Andreas Kling, who once worked at Nokia and was involved in the development of KHTML, and later was one of the developers of Safari at Apple. Initially, the project was created as an application for the SerenityOS operating system, but in the summer of 2024 it was spun off into a separate project and received a donation of $1 million. The browser is written in C++ and is distributed under the BSD license. The project develops its own engine LibWeb, the JavaScript interpreter LibJS, and accompanying libraries.
