Features
Ladybird uses a new browser engine called LibWeb that is being created from scratch by the development team. Unlike SerenityOS, it will also use other open source libraries for development.[3] An ad blocking feature is planned.[7] Unlike most new web browsers, Ladybird does not rely on Chromium or Firefox and uses its own rendering engine and JavaScript engine.[8]
History
The project was initially developed by the SerenityOS community using its internal software libraries implementing specific features (with self-descriptive names prefixed with “Lib”, e.g. LibWeb, LibHTTP, LibJS, or LibWasm).
Ladybird was announced by Andreas Kling, the maintainer and founder of the SerenityOS project, in September 2022.[9]
On June 30, 2024, Kling announced that he would be stepping back from the main project to focus solely on building the Ladybird browser.[10][6] In July 2024 the Ladybird Browser Initiative announced that it was being funded by Chris Wanstrath, the co-founder of GitHub.[7] Ladybird began receiving sponsorships to fund its development including from large companies such as Shopify and Proton VPN.[8]
As of March 2025, it ranked fourth highest on the Web Platform Tests, a suite of tests used by browser developers, below Chrome, Safari and Firefox.[8] It also had the second most conformant JavaScript Engine after Firefox's SpiderMonkey.[8]
