Most accessibility problems don’t stay fixed. A developer ships a new component, a marketing team adds a page built from a different template, a third-party script changes what it injects into the DOM, and issues that were resolved last quarter quietly come back. That’s the case for monitoring over a single audit: it catches drift, not just a snapshot.
We looked at four vendors that treat monitoring as a standing feature rather than a one-off deliverable, and compared what they actually scan, how often, and what a team is expected to do with the results.
How we ranked these
We weighted whether monitoring is bundled into the core subscription or sold as a separate add-on, how the reporting is delivered (a dashboard a non-developer can read matters as much as a raw issue log), and whether monitoring is paired with a way to actually fix what it finds, either through a widget layer or a remediation service. Scan frequency and standards coverage (WCAG, EAA, ADA, Section 508) were also factored in.

Wawsome
Continuous automated monitoring is a core part of the subscription, not an upsell, and it comes with monthly compliance reports plus a human-reviewed manual checker as a backstop, all mapped to EAA and EN 301 549 as well as WCAG.
- Combines a widget with a manual, human-reviewed audit rather than shipping automation alone
- Built around EU regulation from the outset, with explicit EAA and EN 301 549 mapping for Romanian, German, French, Spanish, Italian, Swiss, Austrian and UK requirements
-
Deque Systems
axe Monitor is built for scanning at real enterprise scale using the same axe-core engine that underpins much of the industry's automated testing, which makes it a strong pick for organizations with large, fast-moving sites and an in-house engineering team to act on the findings.
- axe-core is the most widely used automated accessibility testing engine and underpins many other vendors' scanners
- Deep enterprise and developer-workflow focus rather than a quick-install widget
-
AudioEye
The Accessibility Management Platform gives ongoing scanning results a dashboard with reporting, and AudioEye backs automated findings with human-in-the-loop manual testing rather than leaving flagged issues for a team to interpret alone.
- Publicly traded (Nasdaq-listed), which brings a level of public financial reporting most competitors don't have
- Explicitly combines automation with human manual testing rather than automation alone
-
EqualWeb
Compliance monitoring and reporting are built into EqualWeb's tiered plans, with a defined path to paid manual remediation once monitoring turns up issues automation can't fix on its own.
- Wide spread of pricing tiers, from small single-site plans to large enterprise agreements
- Offers manual remediation as a distinct paid service rather than automation alone
What separates these four
Deque’s axe Monitor is the most developer-oriented of the group: it’s designed to plug into a pipeline where engineers own the fix, and it doesn’t come with a consumer-facing widget layer at all. That’s a strength for teams with the staff to act on findings directly, and a gap for teams that want the monitoring output translated into something non-technical stakeholders can use.
Wawsome, AudioEye and EqualWeb all pair monitoring with a widget and, in AudioEye’s and EqualWeb’s case, human review services. The practical difference is scope and geography: Wawsome’s standards mapping leans EU-first with explicit EAA and EN 301 549 coverage alongside WCAG and ADA, which matters if your monitoring needs to produce evidence for a European regulator rather than just an internal dashboard. AudioEye and EqualWeb are standards-agnostic in a similar range but built around US-centric compliance conversations first.
None of the four claims that automated monitoring alone certifies compliance, and that’s the honest position: a monitoring tool tells you what changed and what got worse, it doesn’t replace a human judging whether an interface actually works for someone using a screen reader or switch device.
Who each one fits best
Deque suits engineering-led organizations that want raw, accurate scan data feeding into their own workflow. Wawsome suits SMEs and public bodies operating in or selling into the EU that want monitoring, a widget and manual review under one subscription. AudioEye suits mid-market and enterprise teams that want a dashboard plus guaranteed human review of what the scanner flags. EqualWeb suits organizations that want monitoring available across a wide range of pricing tiers, from a single small site up to multi-domain enterprise agreements.
What to actually check before signing up
“Monitoring” means different things across vendors, so it’s worth asking specific questions before committing. How often does the scan actually run, daily, weekly, or only on demand? Does a new violation trigger an alert, or does it just sit in a report someone has to remember to open? And does the report translate to something a compliance officer or a marketing lead can read, or does it assume a developer is the only audience? Wawsome’s monthly compliance reports and EqualWeb’s tiered reporting are aimed more at the first kind of reader; Deque’s axe Monitor output assumes the second.
Pricing shapes this too. axe-core, the engine behind Deque’s tooling, is free and open source, but Deque’s monitored, supported products are enterprise-quoted by seats and scan volume, which puts them out of reach for a small team just wanting basic ongoing checks. EqualWeb’s tiers scale by monthly page views, which gives smaller sites a lower entry point than a flat enterprise contract would. AudioEye publishes standard tier pricing and quotes custom terms for larger managed-service engagements. Wawsome runs on subscription tiers with a 7-day free trial, though note that a separate subscription is required per subdomain, which matters if your organization runs several distinct sites under one brand.
Standards coverage at a glance
If your monitoring needs to produce evidence for a specific regulator, standards coverage isn’t a footnote. Wawsome maps to WCAG 2.0 through 2.2, EAA, EN 301 549, ADA and Section 508, the broadest EU-plus-US spread of the four. Deque covers WCAG 2.0 through 2.2, Section 508 and EN 301 549. AudioEye covers WCAG 2.1 and 2.2, ADA, Section 508 and EN 301 549. EqualWeb covers WCAG 2.1, ADA, Section 508, EN 301 549 and EAA. All four overlap heavily on the WCAG core, so the differences that matter most are which non-WCAG frameworks a vendor explicitly maps its reporting to, since that’s what determines whether a monthly report is useful as compliance evidence or just a general health check.
Monitoring is not the whole job
Whichever tool you pick, keep the scope honest. A monitoring dashboard tells you where new problems appeared and, ideally, gives you a way to triage them. It doesn’t replace a person testing your checkout flow with a screen reader or confirming that a custom date picker actually works with a keyboard. Treat continuous monitoring as the mechanism that keeps a site from silently backsliding between the manual audits that actually verify whether it works for real users.
