Auto-Lighthouse
An experiment in improving website performance with an AI audit-and-test loop.
The project
Overview
Auto-Lighthouse audits a website, proposes a code change, and measures the result. Improvements are kept; changes that do not improve the score are rolled back. I tested the loop on Rat Radar over 25 rounds.
Details
The experiment
- Lighthouse audits before and after each change
- 25 rounds, with two changes improving the score
- Performance moved from 57 to 74 in the March 2026 experiment
