ProUXAudit opens a web page in a real browser and returns a scored report: findings ordered worst first, each one carrying the evidence it was raised from, and a prioritised fix plan with acceptance criteria you can check after the change ships.
What makes it different is that the scoring is published rather than described. Twenty coverage checks, eight weighted score dimensions, five severity levels with stated penalties, and nine separate ceilings that cap what a score is allowed to claim — all documented, with the arithmetic worked through on a public example report.
The same browser session measures three things a person can check line by line: mobile readiness, accessibility against a pinned rule set, and performance from real page-load timings. If that measurement fails on a run, the report says "not measured" rather than printing a zero. It will not estimate your lost revenue, because that needs your traffic, your margin and a causal link a page audit does not have.
The free plan runs three audits a month, and an anonymous audit needs no account and no email address at all. Starter and Pro are monthly plans with more audits. A fixed-price audit done by a person is available for one-off work.
