What is ACE™ by AccessibilityChecker.org?
Powered by the proprietary ACE™ Engine, it evaluates pages against 100+ accessibility rules, assigns each issue a unique ACE Rule ID, and generates an overall ACE Score, which is a single, trackable compliance metric. Scans complete in under a minute with no installation required on the server side.

Key Features
ACE Impact Classification
Rather than surfacing raw pass/fail results, ACE™ Scanner classifies every detected issue into one of three tiers:
- Legal Risk (e.g., keyboard traps, missing form labels)
- User Impact (e.g., poor color contrast, unclear link text)
- Best Practice (e.g., ARIA optimizations, semantic markup improvements).
This prioritization layer helps teams act on what matters most, both legally and practically, rather than triaging hundreds of undifferentiated violations.
Cross-Page Pattern Detection
ACE™ by AccessibilityChecker.org uses component grouping to identify recurring issues across an entire site. If 200 button elements are missing ARIA labels across 47 pages, ACE surfaces this as a single pattern tied to the shared component. This approach can typically reduce the remediation workload by 50–70%, since most accessibility gaps originate from a small number of shared components.
Flexible Scanning Modes
ACE™ supports full domain crawls, sitemap.xml submission, targeted URL lists, subdomain coverage, staging environment scans, password-protected and authenticated pages (basic auth, bearer tokens, custom HTTP headers), and multi-viewport testing across desktop, tablet, and mobile. JavaScript-rendered and single-page applications are supported via configurable page-load delays and the ACE™ Extension.
Continuous Monitoring
Automated rescans run on daily, weekly, or monthly schedules. Teams receive alerts when ACE Scores drop or new Legal Risk issues are introduced, enabling regressions to be caught at deployment rather than during audits. Every scan result is also timestamped and archived for evidence purposes.
Reporting
Report exports are available in PDF (for legal teams and auditors), Excel (for development and project tracking), and white-labeled PDF formats (for agencies). All reports include the ACE Score, issue breakdown by ACE Impact Classification, per-issue ACE Rule IDs, WCAG principle categorization, and step-by-step remediation instructions.
Who Uses It
ACE™ Scanner is used by development teams, QA engineers, compliance officers, digital agencies, and government contractors. It works with any browser-rendered technology, including static HTML, WordPress, Shopify, React, Angular, Vue, and Next.js among others, and scales from single-page checks to enterprise monitoring of dozens of domains.
Platform Integration
ACE™ Scanner is the detection layer within the broader ACE™ by AccessibilityChecker.org platform. It integrates directly with:
- SmartFix™ (AI-powered code-level remediation)
- Compliance Vault™ (audit evidence management)
- LiveStatement™ (auto-updating accessibility statements)
- A full REST API for CI/CD pipeline integration
All platform products share the same ACE Engine, Rule IDs, and Impact Classification, ensuring consistent data across scanning, fixing, and reporting workflows.
