Accessibility Tool Comparison
This accessibility tool comparison puts AccessBell next to AudioEye, AAArdvark, Siteimprove and Level Access on cost and features. AccessBell is scanning, monitoring and evidence: it is not an overlay, and it does not guarantee legal compliance. Pro is $29 per domain per month or $199 per domain per year on the pricing page. Where a vendor does not publish a price, the table says so and cites a public reference range.
$29 per domain a month versus entry prices from about $69 per month on an annual plan for comparable self-serve checkers, often with far fewer than 500 URLs. The $69 figure is the one recorded in our website accessibility checkers roundup. The table below uses each vendor’s own published price, or says when there isn’t one.

One-time options, which do not renew: Page Report $19, and Domain Audit $79 for up to 500 pages. | AudioEye does not publish dollar amounts on its own plans page. Self-Managed and Managed both say “Talk to an Expert.” Directories (GetApp, Capterra and SoftwareAdvice) list the Automated tier at about $49 per month.

Self-Managed and Managed are “Talk to an Expert.” | Published, including the free plan and the annual prices. | Quote on siteimprove.com. Texas DIR and UK G-Cloud publish list or framework prices for public-sector buyers. They are not a self-serve checkout price. Vendr-observed contracts are about $15,000 to $150,000 or more per year, depending on modules and pages. | Quote for the enterprise platform. AWS Marketplace publishes the Basic tier; other tiers are private offers.

It does not claim to make a site compliant. AccessBellFix applies only fixes you approve. | Listed on the Overlay Fact Sheet. Hybrid model: a script applies automated fixes, and higher tiers add expert services. | Not an overlay. AAArdvark’s FAQ says it is a testing tool, not a quick-fix overlay. | Not an overlay.

The plans page does not describe a self-serve evidence vault. | Issue tracking with assign and verify, a manual testing log, and branded PDF reports. | Dashboards, severity prioritization and multi-team workflows inside the governance suite.

It is not listed on Automated or Self-Managed. | Not stated on the pricing page or FAQ we checked. | Yes. PDF and document checks are part of Inclusivity, including on the UK G-Cloud feature list.

Missouri MOCAP lists audits at $160 per hour. AWS Basic does not say a human audit is included. |
| Legal assurance or indemnity | None. AccessBell does not guarantee legal compliance and does not promise that you will not be sued. The Compliance Vault is evidence of testing and fixes, not an indemnity. | AudioEye Assurance is listed on Managed only. It is not listed on Automated or Self-Managed. The plans page does not publish the dollar terms of that assurance. | Not offered as a legal assurance or indemnity in the pricing page or FAQ we checked. | No published legal indemnity. Framework copy about reducing compliance risk is not an indemnity. | No published self-serve indemnity. Industry write-ups of full programs include legal support inside the quoted services. UserWay’s separate legal-support claims are a different product. |
| Self-serve signup | Yes. Start a trial online. No sales call. | Automated has a “Get Started” path. Self-Managed and Managed are “Talk to an Expert.” | Yes. Plans, including Free, are on the public pricing page. | No. Contact sales. | No for the enterprise platform. AWS Marketplace is a procurement checkout for Basic. Higher tiers are private offers. |
| Best fit | Small and mid-size sites, including storefronts, that want a published price for scanning, monitoring and evidence, and will fix issues in their own code. Not a fit if you need a human expert audit or a legal indemnity in the same contract. | Teams that want automated in-browser fixes on the entry tier, or a vendor to run expert remediation on Managed. Confirm the tier, because the plans page does not show a dollar price. | Teams and agencies that want published multi-site testing plans, manual audit workflow and no overlay. Less of a fit if you need one domain monitored with code fixes and a legal evidence package at a single low price. | Large organizations that want accessibility inside a digital governance suite and can buy by quote. A poor fit if you only need accessibility scanning and do not want SEO, QA or analytics modules. | Enterprises that want a platform plus expert audits, VPAT, training or a managed program, and can buy by quote. The AWS Basic tier is the published starter, and it includes a widget. |
Checked November 2026, and subject to change. A directory listing or a buyer-reported range is not the vendor’s own price. AudioEye’s FY2025 Form 10-K blended figure of about $305 per customer per year is average revenue, not a plan price. Duda reseller SKUs at $9.99 and $99 are channel-specific, not AudioEye’s primary list price. AccessBell Pro also includes email support and role-based permissions. Read the guides to the best ADA compliance software and the best accessibility testing software.
How to Read This Accessibility Tool Comparison
Use the highlighted column when you want a published price for continuous monitoring, guided fixes you approve and a Compliance Vault. AccessBell is an accessibility monitoring tool at $29 per domain per month, for up to 500 URLs. It does not include a human expert audit, and the evidence package does not mean a lawsuit cannot be filed.
Sending Google Ads to a landing page? Fix ads compliance issues starts with the policy Google named. “Destination not accessible” means the page could not be reached or crawled. A WCAG scan does not clear that, and it does help you fix accessibility issues on the URL people click.
AAArdvark publishes every plan, so those prices are the vendor’s. AudioEye’s plans page has no dollar amounts. The about $49 per month line is what GetApp, Capterra and SoftwareAdvice list, and it is labeled that way. Siteimprove and Level Access are quote-first. The Texas DIR list, UK G-Cloud licence band, AWS Marketplace Basic tier, Missouri MOCAP fees and Vendr ranges are the best public references, with the source named in the cell.

Accessibility Tool Comparison Questions
How is AccessBell different from accessibility overlays?
Overlays such as accessiBe and UserWay change your page in the visitor’s browser. AudioEye is a hybrid: a script applies automated fixes, and higher tiers add services. AccessBell finds issues in your code, shows the corrected code and confirms each fix on the next scan. The optional PageAssist toolbar does not claim to make a site compliant.
How is AccessBell different from enterprise platforms?
Siteimprove and Level Access do not publish a self-serve price. The table cites public reference ranges with source labels, including Texas DIR list prices, UK G-Cloud licences, the AWS Marketplace Basic tier and Missouri MOCAP fees. Those ranges are not a checkout price. AccessBell is self-serve at $29 per domain per month or $199 per year.
Where do the prices in this accessibility tool comparison come from?
AccessBell prices are from the AccessBell pricing page. AAArdvark publishes its plans. AudioEye, Siteimprove and Level Access do not publish a full self-serve price, so the table says so and quotes a labeled public range. Figures were checked November 2026.
Does AccessBell offer expert audits or a legal guarantee?
No. AccessBell runs automated monitoring, gives manual testing procedures and records your work in the Compliance Vault. A full human expert audit is not included, and AccessBell does not guarantee legal compliance or promise that you will not be sued. Providers such as Level Access sell expert audits.
Scan a Page, Then Monitor and Fix
The free scan shows the issues on one public page. A 3-day free trial then monitors up to 500 URLs per domain and lets you apply fixes you approve, such as alt text, button names and the page language. Nothing is applied until you approve it.
Pro is a 3-day free trial, then $29 per domain per month or $199 per year. You add a card at checkout and are not charged until the trial ends. Cancel before then and you will not be charged.
Not ready for a subscription? A Page Report is $19 for one page, and a Domain Audit is $79 for up to 500 pages.
