Ladybird Browser Hero Light

​
Welcome to Ladybird

Ladybird is a truly independent web browser, using a novel engine based on web standards.
Ladybird is in a pre-alpha state, and only suitable for use by developers.

​
What makes Ladybird different?

Ladybird stands apart from other browsers in several key ways:
  • Fully independent: Written from scratch, using no code from any other browser engine (not a Chromium shell, not a WebKit port, not a Firefox fork)
  • Singular focus: Dedicated solely to building a new browser engine and browser
  • No monetization: Will never take funding from default search deals or any other forms of user monetization, ever
  • Community-driven: Funded entirely through donations and sponsorships

Architecture overview

Ladybird uses a multi-process architecture with:
  • Main UI process: Handles the browser interface
  • WebContent renderer processes: Each tab has its own sandboxed renderer process
  • ImageDecoder process: Decodes images out of process for robustness against malicious content
  • RequestServer process: Handles network connections out of process

​
