Accessibility Browser Extension

Browser extensions have been the go-to format for accessibility testing tools for years. The most popular accessibility extensions include:

• axe DevTools (Deque) — the most comprehensive extension, runs axe-core in Chrome DevTools
• WAVE (WebAIM) — visual overlay showing issues directly on the page
• ARC Toolkit (TPGi) — thorough testing in Chrome DevTools panel
• Lighthouse (Google) — built into Chrome, includes a partial accessibility audit
• Accessibility Insights (Microsoft) — detailed testing with guided manual checks

These extensions are valuable development tools, but they all share fundamental limitations that CompliScan's web application approach solves. With ADA lawsuits exceeding 10,000 per year and compliance deadlines approaching, teams need more than a single-page manual testing tool.

Every accessibility browser extension shares the same structural limitations:

• Manual testing only — you must navigate to each page, open DevTools, and run the test manually; no scheduling, no automation
• Single-page scope — extensions test one page at a time; a 50-page site requires 50 manual test runs
• No history or tracking — results disappear when you close the tab; no compliance trend tracking over time
• No shareable results — findings live in your browser's DevTools; sharing requires screenshots or manual documentation
• No AI fix suggestions — extensions describe violations and link to documentation but do not generate code-level fixes
• Browser and platform lock-in — most extensions are Chrome-only, excluding Firefox, Safari, and mobile users

Extensions are excellent for developer spot-checks during coding. They cannot serve as an organization's accessibility compliance solution.

CompliScan delivers everything accessibility extensions offer — and more — through a web application that requires no installation:

• Same engine — CompliScan uses axe-core, the same engine powering the axe DevTools extension
• AI fix suggestions — Claude AI generates specific code fixes for every violation; no extension offers this
• Any browser, any device — works in Chrome, Firefox, Safari, Edge, and mobile browsers
• Shareable results — results live at a URL anyone on your team can access; no DevTools knowledge needed
• Compliance tracking — paid plans track your score over time, creating a documented compliance record
• Scheduled monitoring — automated scans catch regressions without manual re-testing

For developers who love their axe DevTools extension during coding, CompliScan is the complement that handles everything the extension cannot: sharing, monitoring, AI fixes, and compliance tracking.

The optimal accessibility workflow uses both extensions and CompliScan, each for their strengths:

• Use extensions during development — quick feedback while coding; test the page you are building in real time
• Use CompliScan for comprehensive audits — full axe-core scanning with AI fix suggestions when you need to assess and remediate
• Use CompliScan for monitoring — paid plans ($49-299/month) automate ongoing scanning; extensions cannot do this
• Use CompliScan for collaboration — share results with designers, QA, product managers, and stakeholders via web links

This combination gives you developer-speed feedback during coding (extension) and organization-wide accessibility management (CompliScan). Most teams find that CompliScan's free tier replaces the need for extensions for ad-hoc scanning, while paid plans provide the monitoring and tracking extensions fundamentally cannot offer.
