Doing Our Share for the Web in 2025
It’s that time of the year which gets us all retrospective and here we are with the last year’s open source contribution statistics, or as we all lovingly say, “the one with the charts”.
Let’s take a look at some of the most popular and exciting projects we worked on last year, especially in browsers and web technologies, and how well we did.
Browser Projects
Like previous years, a lot of our efforts go into this space and it’s one we pay keen attention to. Here’s how much Igalians collectively contributed to the projects in this space.
Chromium
Igalia was the second most-active non-Google contributor! This continues the trend from last year, when Microsoft overtook us as the top external contributor to Chromium for the year while we continue to be the largest non-Google contributor cumulatively. We’ve held on to the third spot since then and it’s been really interesting to continue to work with all the different stakeholders in Chromium. For more details on our work in Chromium and related projects, check out our blog post.
Chart data
| Contributor | Contributions |
|---|---|
| Microsoft | 45.72% |
| Igalia | 19.90% |
| Intel | 7.91% |
| Opera | 5.82% |
| Bytedance | 1.24% |
| Naver Corporation | 1.18% |
| Saqlain | 1.09% |
| januschka.com | 1.02% |
| island.io | 0.92% |
| Suyeon Ji | 0.86% |
However, cumulatively until December 2025:

It’s so amazing to see the activity and collaboration happening in the Chromium project. Cumulatively, we’ve held on to the first spot after Google since we surpassed Opera although Microsoft has been catching up quickly!
Worth noting: Muhammad Saqlain, a Google Summer of Code student working on the Chromium project, ended up being the top unaffiliated contributor to it this year (#7 in non-Google commits)!
WebKit
We’re still the number one contributors (after Apple) to WebKit 💪🏻💪🏼💪🏽💪🏾💪🏿.
Our recent efforts have been focused on lots of invisible internal improvements, most notably the rendering performance improvements as well as the switch from Cairo to Skia. These changes have significantly improved the overall performance and stability of WebKit.

Web Standards
Besides directly working on web browsers, many Igalians contributed to various web standards and organizations. While the immense effort behind standards work is hard to quantify in commit count, sticking with the theme of this post, let’s see how we did in the various projects.

Other projects
There are a number of crucial projects that we’ve focused on this year, including:
- We had a total of 313 commits merged into the Linux kernel, covering a variety of areas like GPU/display drivers, memory management, scheduling and testing. The effect of our contributions was noticeable in some subsystems more than the others, with a whopping 189 commits among these just to the DRM subsystem for instance! To read in more detail about some of our contributions to the most recent release, check out this blog post.
- We were the second-largest contributor in commits to GStreamer, the multimedia framework. We maintain the GStreamer ports of WebKit used on desktops and many embedded devices. Our main focus areas in GStreamer this year included video codecs (VVC/H.266 support), Vulkan video acceleration, WebRTC improvements, and enhancements to GStreamer Editing Services (GES).
- The Mesa 3D Graphics Library is huge and contains open source implementations of pretty much every graphical standard (Vulkan, as mentioned above, for example). This year, we continued our strong contributions to various drivers and components. We ended the year as the fifth largest contributor to the project alongside other major industry players like Intel, AMD, Valve and Google. Our work in Mesa3D has been centred around V3DV for the Raspberry Pi and Turnip for Valve’s upcoming Steam Frame VR headset. To learn more about our work with Valve, check out this blog post.
- We’ve been very involved in work on GL, and contributing to Khronos Vulkan, OpenGL, and OpenGL ES Conformance Tests, including The Vulkan GL Conformance Test Suite Repository where we ended up as the top contributor for the year.
- Igalia is the main contributor to libsoup the HTTP client/server library for GNOME, with nearly half of all the commits in 2025.
Conclusion
Remember that as consultants, we work on projects and initiatives sponsored by our amazing clients — perhaps you’d like to work with us. We would like to thank all of our partners from 2025, and while there was a lot we worked on this past year, we look forward to work on even more interesting and exciting projects in 2026!
