Axes is a layout engine written in Rust.
The goal of the project is simple, to provide a fast and predictable layout engine.
Warning
Axes is still a work in progress. The API may change.
Axes implements a custom layout model. It is not a CSS Flexbox/Grid engine.
If you need CSS compatibility, you should probably use Taffy instead.
But if you need a lightweight and fast layout engine that you can embed into your own engine, Axes might be a better fit.
Axes was benchmarked against Taffy 0.9.2 from crates.io.
Benchmark results can be found in benches/results-26-02-2026.md.
In these benchmarks, Axes performs faster in all tested cases (Approximately 2x faster than Taffy).
Taffy supports significantly more layout features and full CSS-like behavior, which affects performance characteristics. Axes focuses on a smaller, custom layout model.
Contributions are welcome.
