Best ARC Toolkit Alternative — Free Accessibility Scanner

ARC Toolkit is a free Chrome browser extension created by TPGi (The Paciello Group), one of the most respected names in accessibility consulting. The extension runs in Chrome DevTools and tests the current page against a comprehensive rule set, providing detailed reports with WCAG references and severity ratings. It is widely regarded as one of the most thorough free accessibility testing extensions available.

However, ARC Toolkit shares the fundamental limitations of all browser extensions: manual single-page testing only, no scheduled monitoring, no scan history, and no shareable results. Teams that need to test dozens of pages, track compliance over time, or share findings with non-technical stakeholders quickly outgrow the extension model. The lack of AI fix suggestions also means developers must interpret violations and write fixes manually — a time-consuming process that scales poorly.

ARC Toolkit and CompliScan both prioritize thorough accessibility detection but differ in workflow and intelligence:

• Delivery — ARC Toolkit: Chrome DevTools extension. CompliScan: web app accessible from any browser
• AI capabilities — ARC Toolkit: detailed violation descriptions. CompliScan: AI generates specific code fixes
• Monitoring — ARC Toolkit: manual only. CompliScan: scheduled automated scans catch regressions
• Sharing — ARC Toolkit: results in browser only. CompliScan: shareable links, team dashboards, PDF exports

Think of CompliScan as ARC Toolkit's capabilities plus AI intelligence, cloud collaboration, and automated monitoring — accessible to your entire team, not just developers with Chrome DevTools open.

ARC Toolkit's quality is not in question — it is one of the best free accessibility testing tools. Its limitations are inherent to the browser extension format:

• Chrome only — ARC Toolkit runs exclusively in Chrome DevTools, excluding Firefox, Safari, and Edge users
• One page at a time — testing a 50-page site requires 50 manual extension runs with no batch scanning
• No history or tracking — results disappear when you close the tab; there is no way to track compliance trends
• No fix suggestions — violations include excellent descriptions and WCAG references but no ready-to-implement code changes
• Developer-only access — non-technical team members cannot easily use or interpret DevTools-based results

ARC Toolkit excels as a development-time spot checker. It cannot serve as an organization's primary accessibility compliance tool.

CompliScan takes the thoroughness ARC Toolkit is known for and wraps it in a complete accessibility workflow. The axe-core engine provides comprehensive WCAG detection, Claude AI generates code-level fix suggestions for every violation, and the cloud-based platform makes results accessible to everyone on your team.

The free scan works from any browser on any device — no extension installation, no DevTools knowledge required. Product managers can run scans, designers can review findings, and developers can grab AI-generated code fixes to implement immediately. All from a shareable URL.

CompliScan's paid plans add what ARC Toolkit fundamentally cannot offer: scheduled monitoring that catches accessibility regressions automatically. The Shield plan at $49/month runs weekly scans for 3 sites. The Shield Pro at $149/month covers 10 sites with daily scans. For development teams that value ARC Toolkit's detection quality, CompliScan is the natural evolution to a complete accessibility practice.
