Silktide vs EqualWeb 2026: One Scans Your Site, One Patches It
Updated June 2026 · 8 min read
The Bottom Line Up Front
Silktide is a compliance platform — it scans your website, identifies real WCAG violations in your code, and tracks your remediation progress over time. EqualWeb is an overlay widget — a paid JavaScript snippet that claims to automatically fix accessibility without touching your source code. For genuine ADA or WCAG compliance, these are not equivalent options.

| Best for | Government, higher ed, enterprises | Not recommended for genuine compliance |
What Silktide Does
Silktide is a Sheffield-based digital quality platform used extensively across UK local government, higher education institutions, NHS trusts, and public sector organizations — and increasingly in the US among regulated industries and higher ed. It combines automated accessibility scanning with content quality checks, broken link detection, and policy compliance monitoring in a single platform.
The accessibility component of Silktide scans your entire website against WCAG 2.1 and 2.2 guidelines, categorizes violations by severity and WCAG criterion, and produces dashboards that track compliance progress over time. When your team fixes a violation and the site is rescanned, the compliance score updates. This makes Silktide well-suited for organizations running formal accessibility programs with multiple stakeholders and regulatory reporting requirements.
Site-wide WCAG scanning
Silktide crawls your entire site on a schedule, testing every page against WCAG criteria. Violations are organized by type, severity, and page — giving you a complete picture of compliance debt across your digital estate, not just spot checks on individual pages.
Progress tracking and compliance history
Silktide maintains a history of your compliance scores over time. This audit trail is valuable for demonstrating good faith compliance efforts — showing regulators, funders, or courts that you've been actively working to improve accessibility, not ignoring it.
Public sector and regulated industry features
Silktide is specifically designed for organizations with regulatory reporting obligations — UK PSBAR (Public Sector Bodies Accessibility Regulations), US Section 508, and similar frameworks. Features include accessibility statement monitoring, compliance benchmarking, and report exports formatted for procurement and regulatory submissions.
EqualWeb's Overlay Approach
EqualWeb takes a fundamentally different approach: instead of helping you identify and fix violations in your code, it installs a JavaScript snippet that attempts to remediate violations dynamically at runtime. The AI engine claims to auto-generate alt text for images, fix form label associations, improve keyboard navigation, and adjust color contrast — without your developers touching the underlying source.
The appeal is obvious: if you could make your site accessible without development work, why wouldn't you? The problem is that this approach consistently fails to produce genuinely accessible sites — and the legal community has caught up to it.
Why overlay widgets don't work
- AI-generated alt text is frequently wrong or unhelpful — a real screen reader user gets worse information than no alt text in some cases
- The overlay only runs when the JavaScript loads — if it's blocked, slow to load, or conflicts with other scripts, users get the inaccessible baseline
- Screen reader users often find the toolbar itself disruptive to their assistive technology workflow
- Underlying source code violations remain — the DOM patch isn't the same as fixing the actual code
- Multiple ADA lawsuits have been filed and won against sites using overlay widgets, with courts ruling the overlay did not make the site accessible to the plaintiff
EqualWeb issues "Accessibility Certificates" to customers — documents that claim the website meets WCAG standards due to the overlay. These certificates have not protected companies from ADA lawsuits. Courts evaluate whether real users with disabilities can use the site, not whether a certificate exists.
Who Should Choose Each
Consider Silktide if:
- You're a UK public sector organization with PSBAR reporting obligations
- You manage a large digital estate (university, government website, large charity) with multiple editors and stakeholders
- You need compliance dashboards and audit trails for regulatory reporting
- You want a platform that also covers content quality, broken links, and readability — not just accessibility
- Your organization has the budget for a proper compliance program ($500–$2K+/month)
EqualWeb: not recommended for genuine compliance
EqualWeb's overlay widget does not meet the bar for genuine WCAG conformance that courts and regulators evaluate. If you're looking for an affordable accessibility solution, better options include using the free WAVE and axe DevTools browser extensions to find violations, fixing them in your source code, and using an automated monitoring tool like RatedWithAI to track compliance over time. This approach costs less than EqualWeb and produces real results.
Real accessibility monitoring without enterprise pricing
Silktide starts at $500+/month. EqualWeb's overlay doesn't deliver real compliance. RatedWithAI automatically scans your site with axe-core and monitors it continuously for $29/month.

Frequently Asked Questions
Is Silktide WCAG 2.2 compliant?
Silktide tests websites against WCAG 2.2 (released September 2023) in addition to WCAG 2.1. Silktide updated its testing engine to cover WCAG 2.2 criteria including new success criteria around focus appearance, dragging movements, accessible authentication, and redundant entry. For organizations that need to meet WCAG 2.2 (particularly UK public sector organizations following the updated PSBAR technical standard), Silktide's scanner covers the relevant criteria.
What happened to EqualWeb lawsuits?
EqualWeb and its customers have been named in ADA Title III lawsuits alleging that EqualWeb's overlay widget did not make the defendant's website accessible to blind users using screen readers. The legal pattern is consistent with other overlay vendors: plaintiffs who use screen readers successfully argue that the overlay's dynamic DOM modifications disrupt rather than assist their assistive technology, leaving the site functionally inaccessible. Some cases settle; others have proceeded to substantive findings. The key takeaway is that overlay widgets have not demonstrated legal protection in ADA litigation — which is central to why companies buy them.
Does Silktide integrate with CMS platforms?
Yes. Silktide integrates with WordPress, Drupal, Sitecore, Kentico, and other CMS platforms through its browser extension, API, and direct integrations. The CMS integrations allow content editors to check accessibility as they create content rather than discovering violations after publication. Silktide also integrates into development workflows via API for teams that want to incorporate accessibility checks into their deployment pipelines.
How does Silktide compare to Siteimprove?
Silktide and Siteimprove are both digital quality and accessibility platforms with similar target audiences — larger organizations needing site-wide monitoring. Siteimprove is a Danish company that trades on the Copenhagen Stock Exchange and has a larger global market presence, particularly in North America. Silktide is UK-based with stronger penetration in UK public sector. Both offer accessibility scanning, content quality, and analytics. Pricing is similar (both at the $500–$5K+/month range). The choice often comes down to regional customer support, specific integrations, and UI preferences. Neither uses the overlay approach — both find real violations.
Is there a free alternative to Silktide?
Silktide doesn't have a free tier. For organizations that need site-wide accessibility scanning without Silktide's budget, the closest free tools are WAVE (page-by-page browser extension) and axe DevTools (also free, page-by-page via browser DevTools). For automated site-wide scanning closer to what Silktide offers, RatedWithAI provides continuous monitoring starting at $29/month — significantly below Silktide's price point. It uses axe-core for scanning (the same engine embedded in Google Lighthouse) and monitors your full site on a schedule.
