I have a idea for a kind of terminal (but not a terminal emulator) more in the style of ipython. But the trouble is that multi platform is complicated.

Is possible to have a fast html rendered just for the UI and use native code for the rest?

Sure, with Electron/Node you can easily do that: https://nodejs.org/api/addons.html

A good example for a performant Electron/Node application is Microsoft VSCode

Mmm... maybe I was not clear.

I like how html/css work for build the UI, but wish not to use node at all. Also, exist a engine more light and fast than webkit?

if you're using native code anyway, why not just use gtk or qt? they both solve the "multiplatform is complicated" issue, as long as you're willing to compile separately on each platform and host native executables for end users to download.
