UL uses a fork of WebCore/JavaScriptCore (the layout engine and JavaScript engine from WebKit). It is indeed modified (been working on it 7 years) and released open-source on GitHub.

Hi there, lead dev of UL here (seems HN found our beta :)): 1. That Section (5) is left intentionally reserved (empty) since the commercial version of the contract provides commercial license grants. This is typical when offering multiple v

Bit hard to explain without examples but while traversing the beziers in shader, I test if we are equidistant to two or more beziers and do special handling to merge the two unclamped fields (normally we clamp 't' between [0, 1] w

Looks neat! Glad to help.

I actually moved all of that to the CPU (parallel, SIMD) and am using it in Ultralight [1] to generate high-precision SDFs for font-glyphs and small paths. I'll release the GPU-based implementation when I have more time. If you're

Ultralight renders to a virtual GPU command buffer for later consumption by a user-space GPUDriver. We ship implementations of GPUDriver for D3D11 and Metal.

Yep! We plan to expose a C API to make bindings easier to generate.

Interesting, it's not too farfetched of an idea since there is a C++ API for accessing the DOM in WebCore and we have the ability to disable JS completely. I've added this to the issue tracker as an idea to explore. [1] [1] - htt

To minimize latency, Ultralight runs on the main thread, single-process, and outputs to raw virtual GPU command buffers for consumption by the user. I worked in game engines before so I'm familiar first hand with responsiveness as a de

Hi there: Pros (Ultralight is...) - Smaller distributable (25% the size of Electron/CEF or smaller). - Simpler and easier to build (fewer dependencies and smaller codebase). - More configurable (users can do custom handling of file sys

Haha, at ease sergeant, thank you! Building WebKit from scratch was, shall I say, an exquisite learning experience. My first change was re-writing part of the CMake scripts to make it more elegant.

There was actual documentation for 0.8 [1] but the source for it was wiped by an erroneous rm -rf and I couldn't update it for 0.9 in time. Full documentation and tutorials will be published soon. With that said, the SDKs include full

We will be pulling upstream WebKit changes from the Safari stable branch into WebCore, so it's not a "hard hard" fork.

Haha, I totally wrote that up but deleted it at the risk of sounding too fastidious.

Haha, you are welcome! I definitely don't hide, come join our Slack channel here: https://chat.ultralig.ht

Yep! In fact we expose JavaScriptCore API directly to users so your native code can call directly into the VM. Check the samples in the SDK.

Hi Andrew, thanks for the comment! Trust me, no one is more familiar with the issues of Awesomium (cumbersome licensing, slow update schedule, bloat, etc.) than myself and it was this reason that I decided to start over from the beginning.

Great idea! Thanks.

Not to dismiss work done by the Electron team but Electron essentially wraps Chromium via CEF, so, tangentially it was made possible by Google.

It's WebKit-based, not Chromium-based. The only LGPL component of WebKit is WebCore and we have open-sourced our WebCore module here: https://github.com/ultralight-ux/ultralight-webcore

The team is currently me :). Will be hiring soon.

The OpenGL driver is almost complete, it shouldn't be too difficult to port to OpenGL ES. We're definitely interested in targeting embedded devices with this.

That's really interesting! Thanks for sharing. There's actually been several HTML UI projects that "break compatibility with the web" in varying degrees, with some breaking almost completely (eg, Sciter and libRocket) fo

That's a great suggestion and I will make a better comparision with real numbers in the next release. Currently, the memory usage is similar or less than that of Chrome/Safari, with most memory being allocated by the JavaScriptCor

It's not a subset, it's the full WebKit layout engine underneath and supports most modern HTML5/CSS/JS. Ultralight can render full websites just fine and is also a full browser runtime, the SDK ships with a Browser sampl

- The beta is definitely not rock-solid stable yet but reasonably runs a majority of major websites. The current branch of Ultralight is based off of a stable branch of Safari/WebKit. - The Ultralight library itself has no dependencie

Definitely yes on an OpenGL GPUDriver implementation (it's done), Vulkan is still being explored.

This thing HAS existed for a while (CEF/Electron, Awesomium, QtWebKit, GTKWebKit, etc.) but the size, memory usage, and flexibility has always been prohibitive. Ultralight addresses all of those through a new, lightweight WebKit fork g
