A developer from Valve working on the RADV Vulkan driver was once again the most prolific contributor to Mesa in 2025 followed by AMD's Marek Olšák with continued improvements around RadeonSI and Gallium3D.
There were [1]a lot of exciting Mesa OpenGL and Vulkan driver developments in 2025 as recapped last week on Phoronix. For those looking to quantify its development pace and compare the activity to prior years, I ran GitStats on the Mesa Git repository for some numbers for the most prolific contributors to Mesa in 2025 and other interesting metrics.
Mesa in 2025 saw 15,527 commits that added 1,023,056 while removing 840,490 lines, In both line count addition and commit count basis, that's actually lower than the past several years. The last time there were fewer commits in a given calendar year was back in 2021 when there were 15,260 commits but even that year was 1.65 million lines of new code added. On a lines added metric, the 2025 result is the lowest since 2019.
The most prolific contributor to Mesa in 2025 was Samuel Pitoiset of Valve's open-source Linux graphics team. Samuel Pitoiset continues working heavily on the RADV Vulkan driver with countless improvements merged over the past year. Pitoiset was responsible for 1,052 commits last year or roughly 6.7% of all the commits. He was also the top contributor too in 2024. Right behind Samuel was Marek Olšák of AMD with Marek's work typically focused around the RadeonSI and Gallium3D code. Following Marek was Eric Engestrom, Faith Ekstrand, Alyssa Rosenzweig, and Mike Blumenkrantz as the other top contributors. In 2025 there were 336 different authors to Mesa, down from 362 in 2024 or 352 in 2023.
The Mesa source tree is up to around 11,479 files.
And the Mesa source tree is approaching six million lines! 5,993,189 lines as of writing... So it's very possible that this year Mesa will break the six million line threshold.
