A nonprofit-backed browser engine built outside the major tech stacks.

Ladybird is an open-source effort to create a new web browser and rendering engine rather than building on Blink, WebKit, or Gecko. The project is funded through donations and sponsorships under a nonprofit model, with an alpha release planned for Linux and macOS in 2026. Developers can follow progress, test sites, file issues, or build the browser locally from source.

Why it stands out

  • Built as a new engine rather than a fork of the dominant browser codebases.
  • Run by a 501(c)(3) nonprofit with stated limits on sponsor influence.
  • Funding model avoids default-search payments, advertising, crypto incentives, and data collection.
  • Development progress is unusually transparent through monthly engineering updates and public source code.

Good to know

  • The browser is still in active development and is not positioned as a daily-driver release yet.
  • First alpha is targeted for 2026 and aimed mainly at developers and early adopters.
  • Initial full-browser support is focused on Linux and macOS; Windows and mobile are planned later.
  • Using it now requires building from source rather than downloading a stable consumer installer.

Under the radar: If you want to try it before alpha, start from the GitHub repository and the project’s OS-specific build instructions; the site’s quick command is meant for development machines, not polished end-user installation.
