Every report ends in a fix list, worst first: what's wrong, why it matters and what to change. Rubric finds it by checking your pages against hundreds of UX checks and measuring how real visitors use your site, without cookies. Try a fix as an A/B test before everyone sees it, all from one panel your team shares.
For teams looking after their own website, and for agencies and freelancers looking after many.

Observed — Homepage uses technical jargon without explanation: 'MCP' (Model Context Protocol), 'corpus', 'audit', 'checklist' are not defined for unfamiliar visitors. Example: 'serves a curated UX corpus to coding agents over MCP' assumes knowledge.
Issue — The page lacks a low-commitment secondary path — only a single primary action with no fallback for visitors who aren't ready to commit yet.
Measure. Analytics without cookies shows where real visitors drop off: pages, funnels, forms, rage clicks and a click heatmap. For a page with no traffic yet, a predicted heatmap shows where attention is likely to land.
Diagnose. The UX audit checks your pages against hundreds of UX checks and ranks what it finds by severity. A user simulation (beta) sends a visitor you describe through the flow, thinking aloud.
Fix and test. Every report ends in your fix list: one problem, one fix per task. Try a fix as an A/B test on real visitors before everyone gets it.
Every finding, simulation blocker and weekly note draws on the same research, so the advice stays the same wherever you look.
Works before you have traffic: a predicted heatmap and a simulated visitor.
Analytics: see how it works
Where real visitors drop off: funnels, forms, a click heatmap and a weekly read of what to fix, all without cookies. For a page with no traffic yet, a predicted heatmap shows where the eye goes, on desktop and mobile.
Hundreds of checks, up to 7 pages. Findings by severity, each with the fix.

Each finding has four parts: the issue, why it matters, what to do, and the references behind it. Paste the issue into a report; hand the actions to whoever builds the fix.
The page lacks a low-commitment secondary path — only a single primary action with no fallback for visitors who aren't ready to commit yet.
Visitors not ready to act at the primary level have no way to engage; they leave instead of taking any step at all.
A real audit, a predicted heatmap, a simulated visitor and live analytics, on our own site.
A discovery pass finds the pages worth auditing. It's part of the audit.
Behind a login too: you sign in yourself, nothing typed is stored.
Findings grouped by severity, each with the fix. Watch it happen live, step by step.
Claude Code and other MCP clients can call the same checks while they build. One command, approve in the browser, done.
