Automated scan tools for accessibility range from free open source libraries to enterprise platforms costing several thousand dollars per month. Free browser extensions and command-line scanners cost nothing but require technical setup. Paid scanning services typically run from 50 dollars to 500 dollars per month for small sites, while enterprise platforms with monitoring, dashboards, and authenticated page support range from 500 dollars to 5,000 dollars or more per month. Pricing depends on page volume, scan frequency, reporting features, and whether the tool is part of a broader conformance management platform.
| Tool Tier | Typical Cost Range |
|---|---|
| Free / Open Source | No cost. Browser extensions, command-line scanners, and open source libraries. |
| Entry SaaS Scanners | 50 dollars to 500 dollars per month. Small site coverage with scheduled scans. |
| Mid-Tier Platforms | 500 dollars to 2,000 dollars per month. Multi-site monitoring, dashboards, role permissions. |
| Enterprise Platforms | 2,000 dollars to 5,000 dollars or more per month. Authenticated scans, API access, large page volumes. |
| Coverage Reality | Scans flag approximately 25% of accessibility issues regardless of price. |
What You Get at the Free Tier
Free scan tools come in two forms: browser extensions that evaluate one page at a time, and open source libraries that developers can run from a command line or integrate into a build pipeline.
These options are useful for spot checks during development. They evaluate HTML, CSS, and ARIA attributes against WCAG success criteria and return a list of detected issues. The technical knowledge required to set up command-line scanners and interpret raw output makes free tools impractical for non-developers.
Free tools do not include monitoring, historical reporting, multi-user dashboards, or authenticated page support. They are point-in-time checks, not ongoing programs.
What Drives Paid Tool Pricing
Paid scanning tools price based on a few core variables. Page volume is the primary driver: a tool that scans 100 pages costs less than one scanning 100,000 pages. Scan frequency follows closely, as daily scans cost more than monthly scans because of the compute and storage involved.
Authentication support adds cost. Scanning pages behind a login requires a browser extension running inside an active session, which is more complex than scanning public URLs. Tools that support authenticated scanning typically sit in the mid-tier or enterprise range.
Reporting depth also affects price. Basic tools return a flat list of detected issues. Higher-tier platforms provide trend analytics, issue prioritization by user impact and risk factor, role-based dashboards, and exportable reports for legal or executive review.
Entry SaaS Scanners (50 Dollars to 500 Dollars per Month)
At this tier, you typically get scheduled scans of a defined set of pages, a basic dashboard, and email or PDF reports. Page limits are usually low, often capped at 100 to 1,000 pages. These tools work for small websites with predictable content and infrequent updates.
Limitations at this tier include shallow reporting, limited or no authenticated page support, and minimal user management. Teams that need collaboration features or executive-level reporting will outgrow this tier quickly.
Mid-Tier Platforms (500 Dollars to 2,000 Dollars per Month)
Mid-tier platforms support larger page volumes, multiple sites under one account, and team collaboration. Expect features like role-based access, issue assignment, historical trend reports, and integration with project management tools.
Most marketing teams and growing organizations land at this tier. The price covers enough capacity for ongoing monitoring without the complexity or cost of true enterprise software.
Enterprise Platforms (2,000 Dollars to 5,000 Dollars or More per Month)
Enterprise platforms support tens of thousands of pages, authenticated scanning across staging and production environments, API access for custom integrations, and detailed reporting suitable for legal and compliance teams. Pricing at this tier is usually quoted, not published, and scales based on page count, user seats, and contract length.
Organizations under regulatory pressure, with large digital footprints, or with formal accessibility programs typically operate at this tier.
What Scan Tools Cannot Do at Any Price
No matter how much a scanning tool costs, the underlying technology evaluates only what code analysis can evaluate. Scans flag approximately 25% of accessibility issues. The remaining 75% requires manual evaluation by a trained accessibility professional using screen reader testing, keyboard testing, visual inspection, and code review.
Paying more for a scan tool buys better reporting, broader coverage of pages, more frequent checks, and better workflow features. It does not buy a higher detection rate. A 5,000 dollar per month enterprise platform identifies the same categories of issues as a free open source scanner, with the difference being scale and presentation quality.
How Scan Tool Cost Fits Into a Total Accessibility Budget
Scan tools are one line item in a broader accessibility budget. Most organizations also budget for an audit (1,000 dollars to 3,000 dollars to start), remediation work, and possibly a VPAT or ACR (300 dollars to 1,000 dollars for issuance). The scan tool covers ongoing monitoring between audits, not the initial evaluation or the fixes themselves.
Choosing a scan tool based on price alone misses the point. The right question is what the tool needs to do inside an existing program: monitor a known set of pages, surface regressions after deployments, or feed data into a conformance management workflow.
