Ultralight VS qtwebkit

Web rendering would be Blink, with V8 being the JavaScript engine. I believe they have their own UI rendering process.

I know of another company that does something similar for the UI process, but with WebKit instead as the base:

https://github.com/ultralight-ux/ultralight#rocket-dual-high...

What I'd really like to see with CEF et al, is JS being dropped, in favor of directly controlling the DOM from the host language. Then we could, for example, write a Rust (or Kotlin, Zig, Haskell, etc) desktop application that simply directly manipulated the DOM, and had it rendered by a HTML+CSS layout engine. Folks could then write a React-like framework for that language (to help render & re-render the DOM in an elegant way).

Ultralight (https://ultralig.ht/) looks pretty cool. I think another possible option is Servo (https://github.com/servo/servo) – it was abandoned by Mozilla along with Rust during their layoffs a while back (but the project still seems to have a decent bit of activity). It would be great if some group of devs could revive the project, or a company could fund such a revival.

Eventually, we'll need to reflect on, and explore whether HTML+CSS is really the best way to do layout, and we could maybe perhaps consider proting the Android/iOS layout approach over to desktop.

I'm curious if the project will be open-source or do you have plans to go the Awesomium/Ultralight route with both open/closed sources and volume licenses? Or do you plan to offer commercial support services like other open source software?

I’m not tied to any language, but it needs to be able to wrap a c++ library. I started with .NET 7 MAUI - no linux support & very mobile focused. Tried out Electron. Wins on ease and usability, but has massive overhead. (Basic “Hello world” executable compiled to over 200mb) I then discovered Ultralight (https://ultralig.ht/). Big win on size, but was last updated 3 years ago.

tauri exists or if you wanted to ultralig.ht

I agree web stuff is really the best way to develop UIs. Good luck making responsive stuff in C++ for example. The paradigm of HTML, CSS, and JS is extremely powerful and even allows you to use canvas, webgpu, wasm.

There are multiple commercial projects that use web dev paradigm for GUIs:

Nice review, thanks! There are also: Ultralight (based on Webkit), LiteHTML, Tkhtml3 and Lobo Evolution. See also timeline of web engines.

Not so ancient - Otter uses QtWebKit 5.212 from Mar 10, 2020.

AFAIK, Otter Browser uses the latest QtWebkit-ng on Windows. It scores 341 points in HTML5Test. There is also an experimental Qt WebEngine backend.

The main backend for Otter Browser is QtWebkit Reloaded, last updated in 2020, see the screenshot.

As for Otter Browser, there is a bug in QtWebKit. Try using Otter Browser on Qt WebEngine.

Otter Browser is based on QtWebKit-NG, which is from 2020, so still relevant. That said, you can use the nightly WebKit build from Playwright: https://i.postimg.cc/Fz7FwRQW/Playwright.png

Lastly, the other webkit based project, QtWebkit. It is also very lightweight and fast, It also provides a cross-platform render and It has access to the system dialogs. The down side is that you will have to make a Qt App to use it. If you don't want to implement it, then you cannot use It

> I hate that it's based on Chromium though

There aren't really many alternatives. The main one is WebKitGTK, but that comes with its own set of issues (mostly performance/compatibility). You can use qutebrowser with QtWebKit as well, but I wouldn't recommend it - it's based on a 2018 WebKit with many known security issues: https://github.com/qtwebkit/qtwebkit/releases

I had hoped for Servo to fill that gap at some point, but so far that hasn't happened yet: https://github.com/servo/servo/issues/27579

Another possibility is for Geckoview to be ported to Desktop platforms some day: https://mozilla.github.io/geckoview/ - something the people behind Tridactyl would like to happen: https://tridactyl.xyz/ideas/#port-geckoview-to-x86_64

> and Qutebrowser privacy related settings also seem quite limited compared to Firefox... (and even compared to Chromium.)

Can you be more specific? Pretty much anything that's possible to expose (either via a QtWebEngine API or via Chromium commandline arguments) is exposed. Certain things (like deleting cookies belonging to a tab when it's closed) just aren't possible without implementing them in QtWebEngine first unfortunately.

FWIW there's an overview here: https://github.com/qutebrowser/qutebrowser/issues/4045

and Qt has mostly moved to qtwebengine/blink. qt-webkit is sort-of-not-really maintained by very few volunteers. https://github.com/qtwebkit/qtwebkit/releases

While you can still use it with QtWebKit instead, I wouldn't recommend doing so, as that's still based on a 2018 WebKit with no process isolation or sandboxing.
