A11yInspect Accessibility Bookmarklets: Fast, Visual Web Accessibility Testing
Overview
A11yInspect Accessibility Bookmarklets empower developers, designers, QA teams and auditors with instant, browser-based visual insights into web accessibility. Built into the A11yInspect browser extension, these bookmarklets let users surface structural elements, ARIA attributes, keyboard navigation flow and more, directly on live webpages without switching between multiple tools.
Unlike standalone bookmarklets available elsewhere, A11yInspect integrates these capabilities into a comprehensive accessibility testing workflow, helping teams move from spot checks to actionable insights.

What Are Accessibility Bookmarklets?
Accessibility bookmarklets are lightweight JavaScript utilities that run in the context of the current web page to highlight accessibility cues, from real heading hierarchies to link states and image alt text presence. These tools reveal what screen readers and other assistive technologies rely on (but typical visual inspection hides).
Where generic bookmarklets exist as standalone links developers drag into their bookmarks bar, A11yInspect’s implementation is integrated with automated heuristics and enhanced visual feedback to reduce noise and false positives.
Key Features
Headings Bookmarklet: Visualize heading hierarchy (H1–H6 and ARIA roles) to instantly spot structural issues that screen reader users encounter.
Landmarks/Iframes Bookmarklet: See every landmark region and iframe title, the invisible navigation map assistive technology users rely on
Page Title/Language Bookmarklet: Verifies the presence of a <title> element and checks for lang attributes on the HTML element.
Links: Identifies every link on your page and displays its accessible name that reveals which links are descriptive and which provide sufficient context.
Images: Surface alt text (or its absence) for every image on the page, with clear pass/fail indicators.
Hidden/Presentation Bookmarklet: Identifies elements with role=”presentation”, role=”none”, aria-hidden=”true”, and tabindex=”-1″ and ensures they’re genuinely hidden from assistive technologies.
Lists Bookmarklet: Identifies both native and custom list implementations and highlights list items and their attributes, verifying semantic structure.
ARIA Bookmarklet: Inspect every role, state, and property across the entire page — essential for custom component auditing.
Forms Bookmarklet: Displays the association between fields and their labels and verifies accessible names, descriptions and auto-complete attribute values.
Table Bookmarklet: Detects all table elements and highlights structure, verifying proper use of header cells, table rows and data cells.
Grayscale Bookmarklet: Converts your entire page to grayscale, helping you immediately assess whether information is conveyed through color alone.
Text Spacing Bookmarklet: Adjusts spacing across the page, immediately revealing whether content becomes unreadable or inaccessible with increased spacing.
Forced Focus Bookmarklet: Highlights every element that can receive keyboard focus by adding a visible outline, instantly revealing the tab order sequence.
Target Size Bookmarklet: Highlights all interactive elements, using color coding to identify proper sizing and overlapping elements. Eliminates guesswork about sizing compliance.
Tab Order Bookmarklet: Displays the sequential order of focusable elements, revealing whether navigation follows a logical flow or creates confusing jumps.
Who Is This For?
A11yInspect Accessibility Bookmarklets fit a wide range of digital teams, including:
✅ Web Developers & Front-End Engineers
✅ UX/UI Designers
✅ Quality Assurance Professionals
✅ Accessibility Auditors
✅ Product Teams embedding accessibility into agile workflows
These users benefit from immediate visual confirmation of accessibility issues, aiding faster remediation and clearer communication with development teams.
Why Bookmarklets Still Matter in 2026?
Though standalone bookmarklet tools have existed for years as a quick audit practice, they are often fragmented and lack integration with broader workflows. A11yInspect enhances these insights with built-in context, aligning visual feedback with WCAG success criteria and reducing manual guesswork.
