⚡ Quick Verdict
SortSite — Recommended (with caveats)
Tests your actual website against WCAG 2.0, 2.1, 2.2, and Section 508. Finds real violations you can fix. Creates documented compliance evidence. Key limitation: Windows-only desktop app — no cloud monitoring, no Mac support, no continuous scanning.
accessiBe — Not Recommended
Overlay widget under FTC consent order for deceptive marketing. Doesn't fix your underlying HTML. WCAG violations remain in source code, detectable by legal testers. 22%+ of ADA lawsuits target sites with overlays installed.
Best of Both Worlds
If you want SortSite's scanner approach with cloud-based continuous monitoring (no Windows required), RatedWithAI ($29/mo) scans your source code with axe-core and monitors for new violations as your site changes.
What We'll Cover
What Each Tool Actually Does
SortSite and accessiBe are not competing products in any meaningful sense — they produce completely different types of outputs. One generates actionable compliance reports; the other generates a widget and marketing claims that the FTC found to be false.
SortSite: Desktop Scanner
SortSite crawls your website and tests each page against accessibility standards, reporting:
- Specific WCAG violations by page and rule
- Severity levels (A, AA, AAA violations)
- Section 508, EN 301 549 compliance status
- Broken links and browser compatibility issues
- Exportable compliance reports (PDF, Excel)
accessiBe: Overlay Widget
accessiBe installs a JavaScript widget on your site that:
- Displays a floating accessibility toolbar for users
- Attempts to auto-fix some visual issues via JavaScript
- Does NOT change underlying HTML or code
- Does NOT identify specific WCAG violations
- Issues a "compliance certificate" courts have rejected
The key distinction: a scanner tells you what's broken so you can fix it in your code permanently. An overlay attempts to mask issues at runtime — the violations remain in your HTML, still detectable by accessibility auditors, legal testing tools, and screen reader users who encounter them before the overlay JavaScript loads.

⚠️ The FTC Action Against accessiBe
In January 2025, the FTC fined accessiBe $1 million for making deceptive marketing claims — specifically that its AI could make any website "fully WCAG 2.1 AA compliant within 48 hours." The FTC found these claims were false and unsubstantiated. A consent order was approved April 24, 2025, restricting what accessiBe can claim about its product capabilities. SortSite has no equivalent regulatory history.
Pricing Comparison
SortSite is cheaper than accessiBe at entry level. However, SortSite's value is in what it produces — actionable WCAG violation reports — rather than in continuous site monitoring. For teams that need ongoing accessibility monitoring without manual scan scheduling, cloud-based scanners are a better fit.
Feature Comparison
SortSite's Key Limitations
SortSite is a legitimate tool that does what it claims — but it has real-world limitations that lead many organizations to look for alternatives:
Windows-only desktop application
SortSite requires a Windows installation. Mac users, Linux teams, and organizations that standardize on cloud tools don't have a native path to use SortSite. Running it in a Windows VM is possible but adds friction that most teams eventually abandon.
No continuous monitoring
SortSite scans your site when you run it manually. It doesn't watch for new accessibility violations as your content team publishes updates, as your developers push code changes, or as new pages are added to your site. For active sites, this means your compliance posture is only as fresh as your last manual scan.
Desktop licensing model in a SaaS world
SortSite uses per-seat desktop licensing that doesn't scale naturally for distributed teams. Multiple users need separate licenses. Sharing reports requires manual export and distribution. Cloud-based scanners handle multi-user access and report sharing natively.
No integration with CMS or CI/CD workflows
SortSite is a standalone desktop tool. It doesn't integrate with WordPress, Shopify, or other CMS platforms, and it doesn't plug into CI/CD pipelines for automated pre-deployment testing. Developer-focused teams increasingly want accessibility scanning integrated into their build and deployment workflows.
Compliance and Lawsuit Risk
The compliance risk profile for these two tools is completely different:
SortSite risk profile
- Identifies real WCAG violations — creates a documented remediation path
- Reports show regulators you're actively finding and addressing violations
- Multi-standard coverage: WCAG 2.0, 2.1, 2.2, Section 508, EN 301 549
- No FTC regulatory history
- Exportable reports usable as compliance documentation
accessiBe risk profile
- 22%+ of ADA lawsuits target sites with overlay widgets installed
- Courts have rejected "overlay installed = good faith effort" arguments
- FTC consent order restricts accessiBe's compliance marketing claims
- 800+ accessibility professionals signed statement opposing overlay use
- Violations remain in source code — detectable by legal testers

Frequently Asked Questions
Is SortSite better than accessiBe?
For genuine WCAG compliance, yes. SortSite identifies real violations in your site's HTML so you can fix them and document your remediation progress. accessiBe is an overlay that injects JavaScript without fixing underlying code — the FTC fined accessiBe $1 million in 2025 for deceptively claiming its AI could make sites 'fully WCAG 2.1 AA compliant.' SortSite's approach creates defensible compliance documentation; accessiBe's doesn't. SortSite's limitation is that it's Windows-only and requires manual scans — cloud-based scanners address that gap.
Does SortSite work on Mac?
SortSite is Windows-only and doesn't have a native Mac version. Mac users can run it via Windows virtualization (Parallels, VMware Fusion) or use cloud-based alternatives. Free options that work cross-platform include the WAVE browser extension and Deque axe DevTools. For continuous cloud monitoring on any OS, RatedWithAI ($29/month) provides similar WCAG scanning with no software install.
What standards does SortSite check?
SortSite tests against WCAG 2.0 (A, AA, AAA), WCAG 2.1, WCAG 2.2, Section 508 (US federal), and EN 301 549 (European accessibility standard). It also checks for broken links, HTML/CSS errors, and browser compatibility issues. This multi-standard coverage is one of SortSite's strengths for organizations that need to demonstrate compliance across multiple regulatory frameworks simultaneously.
Why do organizations still use accessiBe despite the FTC fine?
accessiBe's marketing targets business owners who are primarily worried about ADA lawsuit risk, not about genuine WCAG remediation. The value proposition — 'install our widget and stop worrying about lawsuits' — is appealing to small businesses with limited technical resources. The FTC found these compliance claims were false, but accessiBe continues to market to this audience with modified language. Organizations that actually understand WCAG compliance choose scanners over overlays.
What's the best free alternative to SortSite?
The best free alternatives to SortSite are: (1) Deque axe DevTools browser extension — catches ~57% of WCAG issues automatically, works on Chrome/Firefox, cross-platform; (2) Google Lighthouse — built into Chrome DevTools, good for quick accessibility audits; (3) WAVE browser extension — from WebAIM, visualizes accessibility issues directly on your page. RatedWithAI's free scan ($29/month for full monitoring) is worth trying if you want a report that covers your whole site rather than page-by-page manual checking.
