Browsers and Client-side Web Technologies

Igalia leads the development of essential projects and components in the areas of web rendering and browsers. We have the most WebKit, Chromium/Blink and Firefox expertise found in the consulting business, including many reviewers and committers.

WebKit is a cross-platform, Free Software web rendering engine. It is used everywhere from major Web browsers  to embedded  platforms. Our numerous contributions to the WebKit project include more than 3500 commits and 2000 reviews since 2009 leading critical areas of the project like the GStreamer media backend, the cairo 2D graphics backend, the libsoup network backend, the ATK accessibility backend and new web technologies like CSS grid layout. Igalia is also the maintainer of the GTK+ port that provides a high quality API for embedders based on the GNOME platform.

Blink started in 2013 as a fork of WebKit. It's currently used by Chrome browser and it's being adopted by other embedders. Since the transition to Blink for a WebKit developer is quite easy and natural, Igalia currently counts with several Blink committers actively working in the project.

Our developers are not only WebKit/Blink experts, they are engineers with solid backgrounds in embedded, graphics, UI design and multimedia. They integrate WebKit in user-oriented environments like the GNOME platform, where we drive the web development effort and maintain its flagship web browser, Epiphany.

As maintainers of the GTK+ and WPE ports of WebKit we have considerable experience creating, maintaining and optimizing ports of WebKit, as well as designing high level APIs for embedders.

Our  developers are knowledgeable about all aspects of Web rendering engines including  JavaScript engine, multimedia, graphics and rendering, networking, accessibility, HTML5 and API design. We can help  you improve the use of your Web framework to maximize the power of your hardware.

If you’re using Fedora and discovered that WebKitGTK+ is displaying blank pages, the cause is a bad mesa update, mesa-18.2.3-1.fc29. This in turn was caused by a GCC bug that resulted in miscompilation of mesa. To avoid this bug, downgrade...
