What Digital Accessibility Software Does
Accessibility software performs several core functions across the development and maintenance lifecycle. These tools scan code for technical violations, monitor websites for regression issues, provide visual adjustments for end users, and integrate with development workflows to catch problems early.
The primary function involves automated detection of accessibility barriers. Software examines HTML structure, checks ARIA attributes, validates color contrast ratios, identifies missing alternative text, and flags form elements lacking labels. These automated checks run against documented patterns that violate WCAG success criteria.
Monitoring represents another major function where platforms continuously scan websites to track accessibility over time. Organizations use these systems to prevent regression after initial remediation, track new issues introduced during updates, and maintain compliance documentation. The platforms generate reports, create analytics dashboards, and send alerts when problems emerge.
Some software attempts real-time remediation through JavaScript injection. These tools modify page behavior dynamically, adding keyboard navigation where missing, attempting to generate alternative text, or adjusting visual presentation. This approach promises immediate fixes without code changes.
Most tools and platforms in the market can best be defined as web accessibility software since they’re only designed for web assets such as websites, web apps, and web content rather than non-web assets such as native mobile apps and software.
How Accessibility Software Works
Modern accessibility software operates through multiple technical approaches depending on the specific tool type and implementation method. Understanding these mechanisms helps organizations evaluate which tools fit their technical architecture and workflow requirements.
Static Code Analysis
Development-time tools analyze source code before deployment, parsing HTML, CSS, and JavaScript to identify patterns that create accessibility barriers. These tools examine DOM structure, evaluate semantic markup usage, check ARIA implementation, and validate that interactive elements include proper attributes. The analysis happens during the build process, allowing developers to fix issues before code reaches production.
Static analysis excels at finding syntactic problems like missing attributes, incorrect ARIA usage, and structural violations. The approach cannot evaluate runtime behavior, test dynamic content changes, or assess whether alternative text meaningfully describes images.
Dynamic Page Scanning
Browser-based scanning tools load pages in real or headless browsers, executing JavaScript and examining the rendered DOM. This approach captures the actual page state users encounter, including dynamically generated content and single-page application behavior.
Dynamic scanning detects issues that only appear after JavaScript execution, such as focus management problems, dynamically inserted content lacking proper attributes, and color contrast issues in rendered states. These tools can simulate user interactions to test form validation, error messaging, and interactive component behavior.
Pattern Recognition and Rules Engines
Accessibility software relies on extensive rule sets mapping code patterns to WCAG violations. Each rule defines a specific pattern that violates accessibility standards, the severity level, and the applicable success criterion. Rules engines process page content against these patterns, flagging matches as potential issues.
Rule sets require constant updates as web technologies evolve and WCAG interpretations clarify. Vendors maintain proprietary rule libraries, though open-source rule sets like axe-core provide standardized detection patterns. The quality and completeness of rule sets significantly impact tool effectiveness.
Technical Limitations of Automated scans
“Automated testing” faces inherent technical constraints that prevent complete WCAG evaluation. These limitations stem from the contextual nature of accessibility requirements and the inability of algorithms to understand meaning, purpose, and user experience quality.
Context-dependent issues represent the largest category of undetectable problems. Software cannot determine if alternative text accurately describes an image’s purpose, whether link text makes sense within surrounding content, or if instructions provide sufficient guidance. These evaluations require human understanding of content relationships and user objectives.
Interaction testing presents another limitation where automated tools cannot fully evaluate keyboard navigation patterns, test screen reader experiences, or verify that focus indicators remain visible through all states. While tools can check for focus indicator presence, they cannot assess whether the indicator provides sufficient visibility across different backgrounds.
Custom components and widgets create detection challenges since automated accessibility tools lack knowledge of intended behavior. A custom dropdown might technically include ARIA attributes but implement them incorrectly for the component type. Tools cannot evaluate whether custom widgets follow expected interaction patterns or provide appropriate feedback to assistive technology.
Integration With Development Workflows
Accessibility software increasingly integrates with modern development practices, embedding testing into continuous integration pipelines, development environments, and deployment processes. This integration shifts accessibility testing left, catching issues during development rather than after deployment.
Build Pipeline Integration
Continuous integration systems run accessibility tests automatically when developers commit code. Failed accessibility checks can block deployments, ensuring issues get fixed before reaching production. This approach requires configuring acceptable violation thresholds since complete automation cannot catch all issues.
Build integration typically uses command-line tools that output machine-readable results. These results feed into reporting systems, track accessibility metrics over time, and generate notifications for team members. Organizations must balance strict enforcement with development velocity, often implementing graduated thresholds that increase over time.
IDE and Editor Plugins
Development environment plugins provide real-time accessibility feedback while writing code. These tools highlight issues directly in the editor, suggest fixes, and link to relevant WCAG documentation. Immediate feedback helps developers learn accessibility patterns and prevents issues from entering the codebase.
Editor integration works particularly well for component-based development where accessibility patterns repeat across applications. Developers can establish accessible component templates, validate them during creation, and ensure consistent implementation across projects.
Version Control and Code Review
Accessibility tools integrate with version control systems to scan pull requests and provide automated code review comments. This integration catches issues before merging, distributes accessibility knowledge across teams, and creates teaching moments during code review.
Automated code review must balance thoroughness with noise reduction. Too many automated comments overwhelm reviewers, while too few miss important issues. Successful implementations focus on high-confidence violations and provide clear remediation guidance.
Project Platforms
The digital accessibility platform market is dominated by scan-based platforms which only provide issue tracking, reports, and analytics based on scan results.
Some organizations opt for general project management software such as Jira, Asana, Wrike, Notion, Airtable, and others. This could very well be because of the lack of platforms that track all audit issues. However, our new Accessibility Tracker platform is audit-based (not scan-based) so all customers can work from accurate data.

The Role of Manual Evaluations
Harvard University’s Digital Accessibility documentation for automated tools emphasizes that “after you’ve done a first pass with the automated tools, you’ll need to follow up with manual testing to ensure that your website is inclusive and accessible.” This requirement stems from the fundamental limitations of automated detection.
Audits (100% manual) by technical accessibility experts evaluates elements automation cannot assess. Experts test with actual assistive technology, evaluate content in context, verify that interactions follow expected patterns, and ensure the overall user experience remains accessible. This human evaluation identifies the remaining 75% of issues automated tools miss.
The manual testing process involves systematic evaluation against each WCAG success criterion. Testers navigate with keyboards, operate screen readers, examine content relationships, and verify that all functionality remains available to users with disabilities. This comprehensive evaluation produces an audit report documenting all violations, not just those detectable through automation.
Cost and Resource Considerations
Organizations evaluating accessibility software must understand the total cost extends beyond licensing fees. Implementation requires staff training, process changes, ongoing maintenance, and supplementary manual testing to reach conformance.
Software licensing models vary from free open-source tools to enterprise platforms costing tens of thousands annually. Pricing typically scales with the number of pages scanned, users accessing the platform, or domains monitored. Additional costs include integration development, custom rule creation, and consulting services.
The hidden cost involves the manual work still required after software implementation. Since tools only detect 25% of issues, organizations must budget for expert audits, manual testing, and validation. This reality means software supplements but doesn’t replace human expertise.
Key Insights
Digital accessibility software provides automated detection, monitoring, and workflow integration capabilities that support accessibility programs. These tools detect syntactic violations, track issues over time, and integrate with development processes. However, the contextual nature of accessibility requirements means automated tools can only identify approximately 25% of WCAG violations.
Organizations must understand that current software cannot deliver full WCAG conformance without manual expert evaluation. The technology excels at finding technical patterns that violate accessibility rules but cannot evaluate meaning, context, or user experience quality. This limitation isn’t a failure of specific vendors but reflects the fundamental challenge of automating contextual evaluation.
Frequently Asked Questions
What percentage of accessibility issues can software detect automatically?
Automated software typically detects approximately 25% of WCAG issues. This percentage covers technical issues with clear patterns like missing labels, color contrast failures, and structural problems. The remaining 75% requires human evaluation to assess context, meaning, and interaction quality.
How much does accessibility software typically cost?
Pricing ranges from free open-source tools to enterprise platforms exceeding $50,000 annually. Costs depend on scanning volume, user seats, domains monitored, and included features. Organizations should also budget for training, integration, and supplementary manual testing.
Can accessibility software fix issues automatically?
No. Overlays / overlay widgets attempt automatic fixes through JavaScript injection or code modification. However, these rendered adjustments are superficial. No code or content is remediated. Also, complex problems requiring context understanding, content rewriting, or interaction redesign need human intervention.
