HalfAccessible - Accessibility Toolkit

Description

Free WCAG accessibility Chrome extension: target size checker, text spacing, axe audits, HTML copier, URL crawl & DOM insights. HalfAccessible - Accessibility Toolkit is a free Chrome extension for web accessibility testing, WCAG compliance checks, and accessibility reporting — directly in your browser side panel. WHAT IS HALFACCESSIBLE? HalfAccessible is an accessibility testing toolkit for Chrome that helps developers, QA engineers, designers, and accessibility professionals find WCAG issues, validate interactive target sizes, test text spacing readability, run automated axe-core audits, copy HTML for bug reports, crawl site URLs, and inspect page structure — without leaving the page you are testing. Whether you are building a new website, auditing a client site, or preparing for ADA or WCAG compliance review, HalfAccessible gives you practical tools in one side panel so you can test faster and report issues with confidence. WHO IS HALFACCESSIBLE FOR? Web developers fixing accessibility bugs during development and code review QA engineers and accessibility testers running WCAG audits on single pages or full websites UI and UX designers validating target sizes, spacing, and readable layouts Content strategists and SEO teams mapping site URLs and document links before audits Agencies and freelancers delivering ADA-compliant, inclusive websites for clients Product teams who need a lightweight alternative to heavy desktop accessibility tools KEY FEATURES Target Size Checker (WCAG 2.5.8 Target Size Minimum) Hover over tabbable elements such as buttons, links, and form inputs to see live bounding box dimensions on the page. Each element shows a Pass or Review label based on whether it meets the 24 by 24 pixel minimum target size. Use this during design QA and mobile testing to catch touch targets that are too small before they reach production. Text Spacing Tester (WCAG 1.4.12 Text Spacing) Apply increased line height, letter spacing, word spacing, and paragraph margins to the current page with one toggle. Instantly verify whether your content reflows correctly and stays readable when users apply custom text spacing — a common requirement for users with cognitive disabilities and low vision. Toggle off to restore the original layout without reloading. Automated Accessibility Audits (powered by axe-core) Run automated WCAG scans on the page you are viewing. HalfAccessible detects common violations including missing alt text, ARIA attribute issues, improper heading hierarchy, form label problems, color contrast issues flagged by axe, and more. Expand each violation to read the description, help text, failure summary, and affected HTML nodes. Click to highlight failing elements directly on the page. Full-site automated crawl Scan an entire website on the same domain starting from the homepage. Set a page limit or crawl the full site. Watch live progress as pages are discovered, queued, and processed. Cancel a crawl at any time. Export all violations to a CSV file for reporting. Saved scan history is stored per domain so you can reload past audit runs without re-scanning. URL Crawl and Site Inventory Discover every same-domain URL linked from your site without running accessibility scans. Useful for content audits, site mapping, and QA planning before a full accessibility review. Export the complete URL list to CSV with status, source page, and timestamp. Export document link URLs in a separate CSV so you can track downloadable files (for example ebooks and office documents) that may also need accessibility review. HTML Code Copier Hover over any element on the page to highlight it, then copy its HTML snippet to the clipboard with one click. Speed up bug reports, Jira tickets, remediation handoffs, and code reviews. Especially useful when auditing semantic HTML, landmark regions, ARIA roles, schema markup, and component markup during accessibility fixes. DOM Insights Panel Browse a structured inventory of accessibility-relevant elements on the current page, organized into categories: Interactive elements: buttons, links, and forms Content elements: headings, lists, images, and tables Structure elements: landmarks and iframes For each item, see computed labels from aria-label, alt text, visible text, title, and value attributes. Review truncated HTML snippets, all aria attributes, and warnings for missing text such as empty link text or missing alt text. Highlight any item on the page for manual inspection. WHY DEVELOPERS AND TESTERS CHOOSE HALFACCESSIBLE All-in-one side panel Manual inspection tools, automated axe-core scans, URL crawling, and DOM insights live in one Chrome extension. No need to switch between multiple apps during an audit session. Works on live websites Test staging environments, production sites, or local development URLs over http and https. Open the side panel on any supported tab and start testing immediately. Built for real audit workflows Export CSV reports, save scan history per domain, highlight elements on the page, and copy HTML in one click. These features reduce repetitive manual steps so your team spends less time documenting issues and more time fixing them. WCAG-aligned testing Target size checking aligns with WCAG 2.5.8. Text spacing testing aligns with WCAG 1.4.12. Automated scans use axe-core rules mapped to widely adopted WCAG success criteria used in accessibility compliance programs worldwide. Accessibility and SEO go together Semantic HTML, descriptive alt text, logical heading hierarchy, readable text spacing, and proper landmark structure help both assistive technologies and search engines understand your content. Fixing accessibility issues often improves crawlability, user experience, and content quality at the same time. Lightweight and browser-native HalfAccessible runs as a Chrome side panel extension. No separate desktop install required. Ideal for developers who already work in Chrome DevTools and want accessibility testing integrated into their daily browser workflow.

HalfAccessible is a free Chrome accessibility testing extension. Does it work on any website? It works on standard http and https web pages. Browser internal pages such as chrome:// URLs, extension pages, edge:// pages, about: pages, and DevTools are not supported. What automated rules does it use? Automated scans are powered by axe-core, one of the most widely used open-source accessibility testing engines for detecting WCAG violations in web applications. Can I audit an entire website? Yes. Use the Automated tab to run axe-core scans across every page on the same domain, or use the URLs tab to inventory all links and document URLs without running accessibility scans. Does it fix accessibility issues automatically? No. HalfAccessible identifies, lists, and highlights issues so your development team can fix them in code. It is a testing and reporting tool, not an auto-remediation tool. Does it store my data? Scan results and crawl history are saved locally in your browser per domain. Your audit data stays on your device. What WCAG level does it test against? Automated axe-core rules cover many WCAG 2.x Level A and AA issues. Manual tools support WCAG 2.5.8 target size and WCAG 1.4.12 text spacing testing. Automated tools catch a large portion of issues, but a complete WCAG audit still requires manual review for criteria automation cannot fully evaluate.
