I maintain Taffy: AMA.

I am currently in the process of building a wider browser engine / GUI toolkit on top of it (https://github.com/dioxuslabs/blitz). As part of that I am implementing a lot of the messier parts of CSS layout (floats, etc), and also grinding on fixing all the WPT tests which we track here: https://blitz.is/status/wpt/css/css-flexbox.

The vision is a complete standalone implementation of the web layout algorithms that can be easily embedded (with individual algorithms enabled/disabled on a pay what you use basis), and which can also be part of a modular ecosystem of browser engine components that make it easier for people to create new browser engines.

Beyond Blitz, some notable users are:

- Servo which uses it only for CSS Grid

- Zed which uses it via it's GPUI toolkit.

Thanks for all this! I used Blitz a while ago for a product research spike around composing HTML to be rendered directly in a terminal with kitty or iterm's image protocol:

I used it in https://fschutt.github.io/printpdf for the HTML-to-PDF layout, just as a note. It is very useful, thanks for your work. Good luck on Blitz.
