I use Safari as my main browser on macOS and I also use Epiphany/GNOME Web as my primary browser on Linux.
But, I need to use Penpot on Firefox as the performance is much better on Firefox. On Safari, the document starts to lag and becomes unusable as soon as it becomes a little complex.
Can we expect performance improvements on Webkit based browsers?
We are already working on performance improvements for all browsers engines, but webkit engine as-is for operations that penpot does is a bit slower, and has more memory restrictions. We will try to do our best on it but we can’t guarantee the performance parity with blink/firefox. And it always depends if your browser has or not hardware acceleration (that in fact depends on the browser, operating system, etc…)
