ACE vs AudioEye: How to Choose Between the Two
Disclosure: AccessibilityChecker.org owns ACE™, one of the tools in this comparison. We’ve evaluated it with the same rigor and honesty as AudioEye.
AudioEye is one of the biggest names in web accessibility, with a hybrid model that combines automated scanning, an accessibility overlay, and human expert review. That makes it a useful comparison for ACE™.
When it comes to ACE™ vs AudioEye, both platforms cover a lot of the same ground, including continuous monitoring, automated detection, and manual expert audits, but differ in where the remediation work actually happens and who’s doing it.

ACE™ vs AudioEye: The Basics
ACE™ is the accessibility testing platform built by AccessibilityChecker.org. It scans your live site against WCAG 2.2, ADA, Section 508, the European Accessibility Act, and EN 301 549, then classifies every issue it finds by ACE Impact Classification: Legal Risk, User Impact, or Best Practice.
Suggested fixes come from SmartFix™, and manual expert audits are also available for teams that want a deeper, human review layer on top of automated scanning.
AudioEye is a publicly traded digital accessibility company offering automated scanning, an accessibility overlay that applies runtime fixes, and continuous monitoring across its plans.
On its Self-Managed and Managed tiers, IAAP-certified experts review flagged issues and write custom fixes, and AudioEye also offers a guaranteed financial protection program (AudioEye Assurance) against WCAG-related demand letters and lawsuits.
Both platforms monitor continuously and offer manual expert review. That part of the toolkit looks pretty similar on paper. Where they diverge is remediation: ACE™ centers on suggested fixes to your actual source code, reviewed and approved by your team before anything goes live.
AudioEye leans more on its overlay technology to apply fixes at runtime, with human experts available to write custom fixes for issues the overlay and automation alone can’t resolve.

Platform Pros and Cons
- Fixes happen in your actual source code, with your team approving what changes

- Continuous monitoring is standard on every plan, not an upsell
- Manual expert audits available for teams that want a deeper human review layer
- Transparent, published, self-serve pricing per domain
- No bundled legal-defense guarantee if you're issued a demand letter
- Requires some developer involvement to implement suggested fixes
- Full platform functionality is behind a paid subscription (a free trial is available)
- Overlay-based automated fixes can address common issues quickly, right out of the box
- Managed plans add expert-written custom fixes and manual audits on top of automation
- AudioEye Assurance offers real financial backing if you're facing a WCAG-related claim
- Bundles adjacent services (document remediation, mobile audits, closed captioning) many competitors don't offer natively
- Long track record and a large existing customer base
- Pricing isn't published; getting an actual number requires a demo or sales call
- Full remediation depth and legal protection require the more expensive Managed tier, not the entry-level plan
- Overlay fixes run at the browser level, so your source code itself doesn't change unless you're also using the developer tools on Self-Managed or above
ACE™ vs AudioEye: Features
Next, let’s get into how the two platforms actually differ once you look past the marketing.
Remediation approach
This is the main difference between the two tools. ACE™ generates suggested, code-level fixes through SmartFix™ for supported issue types, with every fix reviewed and approved by your team before it touches your live site.
AudioEye’s automated tier applies fixes through its accessibility overlay, adjusting the experience at runtime for common, well-understood issues. It’s only on the Self-Managed and Managed plans that human experts get involved to write custom fixes for more complex issues that the overlay and automation alone can’t fully resolve.
Scanning and monitoring
Both platforms take a full-site, continuous approach here. ACE™ Scanner crawls your entire domain on a schedule, plus unlimited on-demand rescans, all of which is included in a standard subscription. Manual expert audits are also available for teams that want a human review layer alongside the automated scans.
AudioEye’s Automated plan includes continuous monitoring out of the box too, plus an Accessibility Help Desk where end users can report issues directly. Self-Managed and Managed plans add expert audits on top of the automated scan, similar in spirit to ACE™’s manual audit option.
Issue prioritization
ACE™’s Impact Classification sorts every issue into Legal Risk, User Impact, or Best Practice, giving teams a way to triage a long issue list by consequence rather than by WCAG conformance level alone.

AudioEye surfaces issues through its automated scans and expert audits, but doesn’t publish an equivalent risk-tiering framework. Its comparable value-add is AudioEye Assurance. Rather than helping you prioritize legal risk yourself, it offers a guarantee of limited financial protection if a WCAG-related claim comes in anyway (available only with Managed plans that include Assurance).

Reporting formats
ACE™ exports reports in PDF (for stakeholders and legal teams), Excel (for developers), and white-labeled PDF formats for agencies, broken down by ACE Impact Classification and WCAG principle.
AudioEye’s platform includes a dashboard summarizing fixed and outstanding issues, and Self-Managed and Managed plans add formal expert audit reports, useful for teams that need documentation beyond a live dashboard.
ACE™ vs AudioEye: Pricing
AudioEye organizes its offering into three tiers, none of which currently publish exact self-serve pricing on AudioEye’s own site:
- Automated: Overlay-based automated monitoring, fixes, and online support that’s listed as a “Get Started” self-serve entry point.
- Self-Managed: Adds developer tools, expert guidance, custom training, and expert audit and reporting.
- Managed: AudioEye’s team handles remediation for you, with expert-written custom fixes and access to AudioEye Assurance (limited financial protection against WCAG-related demand letters and lawsuits).
Because AudioEye doesn’t publish rate cards, getting an exact number for your site means requesting a quote directly from their sales team.
ACE™ Scanner is subscription-based, billed per domain, with three self-serve tiers plus a custom option:
- Lite: $69/domain/month (billed annually) for up to 25 URLs
- Starter: $119/domain/month (billed annually) for up to 100 URLs
- Growth: $249/domain/month (billed annually) for up to 500 URLs
- Tailored: custom pricing for multiple domains or more than 2,000 pages
All plans include WCAG 2.2 AA support, automated evidence collection, AI-assisted fixes for supported issues, continuous monitoring and alerts, and auto-updating accessibility statements.
A 7-day free trial is available on every plan.
The Final Verdict
If you want a mix of fast, automated overlay fixes and the option to add expert-written fixes and a legal-protection guarantee as you scale up, AudioEye’s tiered model is built for that, with pricing that reflects how much of the work you hand off.
If you want to fix accessibility issues directly in your source code, with full visibility into what’s changing and why, and transparent, self-serve pricing to get started, ACE™ Scanner is the more direct route.
Both platforms offer continuous monitoring and manual expert audits, so the real decision point is remediation. Do you want your team implementing reviewed, code-level fixes, or do you want more of that work handled through AudioEye’s overlay and expert services?
Plenty of teams find a place for both: ACE™ to drive ongoing fixes into the codebase, and a service like AudioEye’s Managed plan for the added layer of overlay coverage and legal protection on top.
