Drop a URL. Get a complete usability audit in minutes. Parallax evaluates your product against Nielsen's 10 heuristics, WCAG 2.1 accessibility standards, and 25+ usability criteria — automatically, with no test setup required.
Most UX audit tools are checklists you fill out yourself, or platforms that require you to recruit participants, design test scenarios, and spend weeks analyzing results. Parallax is different.
You give Parallax a URL. It crawls your product, maps every page and interaction, evaluates each screen against established usability frameworks, and returns a scored report with specific findings and fix recommendations — in under 3 minutes.
The free tier includes a complete heuristic evaluation against Nielsen's 10 usability heuristics — the gold standard in UX research, originally developed at Sun Microsystems and used by product teams at every major technology company. It also includes a WCAG 2.1 accessibility scan that checks for contrast failures, missing labels, keyboard navigation issues, and screen reader compatibility.
Together, these two frameworks cover the most common and highest-impact usability issues found in production software. Most teams have never done a structured audit. This is the fastest way to find out what's broken.

No. Parallax runs entirely in the cloud. You just paste a URL. No browser extension, no code snippet, no SDK integration required.
Manual user testing captures how real users behave — valuable but expensive and slow. A heuristic audit evaluates your product against proven usability principles instantly and at low cost. Most teams should do both; Parallax makes the heuristic audit accessible enough to do every week.
Most UX issues sit undiscovered for months because audits are expensive and slow. Parallax makes a thorough audit available to any team, any time.
