The Ladybird Project, an initiative building a new web browser from scratch, has announced a strategic shift from C++ to Rust. This transition aims to improve memory safety and reduce vulnerabilities within the browser's architecture.
Gradual Migration Strategy
The migration is already underway, with the LibJS (the browser’s JavaScript engine) being the first major component to adopt Rust. While the project is moving toward a memory-safe future, the transition will be incremental:
- Priority on Security: Rust is being introduced specifically to mitigate memory-related bugs common in C++.
- Gradual Implementation: The codebase will remain primarily C++ for the time being, with Rust components integrated over time.
- Engine Update: Modernizing the LibJS engine is the first step in this long-term language migration.
By incorporating Rust, Ladybird aims to create a more robust and secure browsing experience while maintaining its mission to build a completely independent web engine.
