Traditional UX audits take weeks. Get a research-backed baseline in about 30 seconds, then bring in experts where context matters.
Every finding is backed by published research: Fitts's Law, Hick's Law, WCAG guidelines, and 165 more criteria.
167 Audit Criteria. Published research. About 30 seconds. Transparent reasoning.
Heuristic evaluation is a usability inspection method where an interface is systematically assessed against a set of recognized design principles called heuristics. The methodology was formalized by Jakob Nielsen, whose 10 usability heuristics (visibility of system status, match between system and real world, user control, consistency, error prevention) became the foundation of modern UX evaluation.
Interface Audit extends this approach to 167 Audit Criteria drawn from cognitive psychology, human-computer interaction research, and WCAG 2.1 accessibility guidelines. Each criterion is supported by published literature, giving every finding an evidence base instead of relying on consultant opinion.
Unlike automated performance tools that measure load speed or Core Web Vitals, heuristic evaluation identifies design quality issues: cognitive overload, unclear navigation, inconsistent visual hierarchy, poor error messaging, and friction in conversion flows. These are the issues that drive users away without showing up in analytics dashboards.
The free audit runs a heuristic scan in about 30 seconds. The full report adds multi-device testing and 14 or more detailed findings with severity scores and implementation recommendations.
Founders launching a new product use the audit to catch usability issues before they reach real users. A single friction point in a signup flow or pricing page can cost conversions that are invisible in analytics until the audit surfaces them.
Designers use it to validate decisions against established research rather than defending subjective choices in reviews. When a recommendation is backed by published findings in cognitive psychology or WCAG standards, it moves the conversation from opinion to evidence.
Marketing teams use the audit before running paid traffic campaigns. Sending ad clicks to a page with high cognitive load, unclear calls to action, or poor mobile usability wastes budget. The free audit identifies these problems in about 30 seconds.
Developers use it as a fast accessibility pre-check before handing off to QA. The audit covers automated WCAG check failures, color contrast failures, missing focus states, and interactive element sizing, issues that are faster and cheaper to fix before a release than after.
A UX audit is a systematic evaluation of a website or application against established usability principles. Interface Audit analyzes your site against 167 research-backed Audit Criteria, covering usability, accessibility, and conversion optimization.
Enter any URL and get an instant analysis in about 30 seconds. The free audit runs a heuristic evaluation against 167 Audit Criteria and opens your first finding with its severity rating and an actionable recommendation, with no signup or email required, on the desktop view of your page. Enter your email to unlock half of your findings for free, at least three.
The audit evaluates usability heuristics, automated WCAG accessibility checks, visual hierarchy, navigation patterns, mobile responsiveness, cognitive load, and conversion optimization. Each finding is tied to a specific research-backed Audit Criterion.
Heuristic evaluation is a usability inspection method where an interface is assessed against recognized usability principles called heuristics. Developed by Jakob Nielsen, the original 10 heuristics cover visibility of system status, match between system and the real world, user control, consistency, error prevention, and more. Interface Audit extends this to 167 Audit Criteria derived from cognitive psychology, HCI research, and WCAG accessibility guidelines.
Google Lighthouse measures performance metrics: load speed, Core Web Vitals, and basic accessibility violations. Interface Audit evaluates usability and UX design quality: cognitive load, navigation clarity, visual hierarchy, conversion friction, and design principle adherence. The two tools complement each other. Lighthouse tells you if a page is fast; Interface Audit tells you if it is easy to use.
