Skia (via SkiaSharp) is the rendering backend for my vector graphics diagramming application (https://vexlio.com). I chose it in part because it had much better performance than Cairo when I was testing both. Also the MIT license was more appealing to me than Cairo's LGPL or Mozilla Public License.

Looks like a nice project. For my own (web development) kind of projects I love to diagram infrastructure, Classes, etc.

But, I do nearly all my work on Linux -- which is a pity because I'd love to try out a tool like Vexlio.

For now I guess I'll continue to stick with yEd, because it actually works everywhere (java works).

Site looks great; well done!

That's the first question that occurred to me so I web-searched.

Seems it is faster and has a broader API. I sort of expected that Raph Levien(1) might have contributed or that Cairo would be part of the base of Skia. But apparently not.

(1) works at Google and wrote Cairo

I did not write Cairo, I wrote libart, and that was a long time ago. I'm good friends with several of the Skia authors, but don't actively work on it myself.

Oh, thanks for the correction.

Note that Skia is a C++ library and does not provide a stable C API.

Skia has a C API under development that is our approach to API stability, but it is not comprehensive and still being added to (sometimes by our clients to get access to the APIs they need).
