GNOME developer Sophie Herold has shared some interesting end-of-year code stats for the GNOME project. The “GNOME” codebase is up to 6,692,516 lines of code at the end of 2025 with 1,611,526 lines of that being from GNOME apps. Where the data gets interesting is on the programming language breakdown in different areas.
Of the official GNOME Core apps, Sophie found that 44.8% of them are written in the C programming language. That’s followed by Vala with 20.7% and then JavaScript at 13.8%. Following JS is Rust with 10.3% of the GNOME Cores apps codebase being in Rust. Trailing Rust is Python at 6.9% and C++ at 3.45%.
You could always read the original source and find out the intent, but who has time for that?
The bizarre thing is that they are only analysing something like 40 programs/library. You could reach the same conclusion clicking through their gitlab for a few minutes.
The translation rate is the actually interesting part.
