Servo 2025 Stats

Summary

Servo 2025 Stats This is a brief blog post to highlight the growth of the Servo community in recent years, particularly since Igalia took over the project maintenance in 2023. Note that this doesn’t talk about the technical achievements, though there have been tons of them in the last years. A picture is worth a thousand words so just take a look at this slide from my latest Servo talk which shows how google.com was rendered with Servo at the beginning of 2023 vs September 2025. Slide showing screenshots of Servo rendering google.com in January 2023 vs September 2025 PRs numbers So like we did last year, let’s take a look at the PRs merged on the main Servo repository on GitHub since 2018. 2018 2019 2020 2021 2022 2023 2024 2025 PRs 1,188 986 669 118 65 776 1,771 3,183 Contributors 27.33 27.17 14.75 4.92 2.83 11.33 26.33 42.42 Contributors ≥ 10 2.58 1.67 1.17 0.08 0.00 1.58 4.67 8.50 PRs: total number of PRs merged.

As a clarification, these numbers don’t include PRs from bots (dependabot and Servo WPT Sync). Checking this we can see we are close to double the numbers from last year! The numbers in 2025 are way bigger than in the previous years (even checking the numbers from 2018-2019), showing a healthy community working on Servo. The next chart is a different view of the same data but split per month, with the number of PRs landed every month, the number of contributors and the number of contributors with more than 10 patches. It shows the evolution over the years and the high activity last year. Number of contributors Now let’s focus on the last 3 years, since the project reactivation, and the numbers of contributors to the Servo project. 2023 2024 2025 Contributors 54 129 146 ≥ 100 PRs 1 (2%) 3 (2%) 8 (5%) ≥ 10 PRs 8 (15%) 29 (22%) 43 (29%) Only 1 PR 31 (57%) 53 (41%) 55 (38%) The number of contributors to Servo ...
