About Nautilus
Nautilus is a public leaderboard for comparing how effectively websites support real people across common user experience dimensions.
What we measure
We evaluate public websites across accessibility, speed, trust, navigation, content, mobile experience, first impression, layout, and color. The overall score provides a comparable summary while the dimension scores show where a site is strong or falling behind.
Why it exists
UX quality is difficult to compare when every review uses different criteria. Nautilus applies one repeatable framework across a broad set of public sites so teams can move from opinion to evidence and context.
