Audityxe is a free website audit tool that provides an instant analysis of a given URL, generating scores and fix recommendations for search engine optimization (SEO), performance, accessibility, security, and user interface/user experience (UX). The tool parses the site’s actual HTML, HTTP headers, redirect chain, robots.txt, sitemap.xml, live-sampled links and images, and performs a real browser-rendered performance and accessibility pass. Scores are derived from deterministic parsing of real signals rather than from language model guesses or screenshots, ensuring that the same page produces the same score each time. The audit is executed live at the moment the user clicks Analyze, and full results are never stored server-side; the only exception is the domain’s latest score and date, which are retained to power an embeddable badge. The tool categorizes its features into several key areas. It offers live, uncached audits with deterministic scoring and transparent limits that clearly state what it cannot measure (such as JavaScript-rendered content or real Core Web Vitals). Users receive an evidence-based report with precise code fixes and a list of what to ship in under one minute. An interactive feature called Audit Defender presents users with real audit issues and a 60-second timer, requiring them to select the correct fix for each issue across SEO, performance, security, accessibility, UI/UX, and mobile categories. The platform operates on a free tier that uses the same engine as paid plans, with no limitations on functionality. Typical use cases include indie makers, marketers, and agencies who need a repeatable, verifiable audit report rather than a consultative retainer. The workflow involves dropping any public URL into the input field, triggering a live scan, and immediately viewing scores and actionable fixes. No account is required beyond a login email, and the service does not sell data or use third-party advertising trackers. Technical requirements are minimal: the user only needs a web browser and a URL to test. The application is built by Zelvior Labs and is available as open-source code on GitHub under the repository github.com/zelvior/audityxe.
