The AI policy for Servo, which prohibits AI contributed code (but allows you to use AI to inspect and learn about the codebase), was written in mid-2024, which seems like an eternity ago.

But even in June 2026 they reiterated this ban and added CI checks to automatically reject AI-coauthored patches [1].

> For developers of Servo itself, please note that per project policy, you must not use the output of large language models or other generative AI tools in your contributions. To help us enforce that, we now have CI checks that reject AI agents as coauthors (@SimonSapin, @delan, #44723).
