How to choose a website compliance checker
Last updated June 11, 2026
A website compliance checker is a tool that tests a site against legal requirements: accessibility (ADA/WCAG), privacy (CCPA, GDPR), marketing and subscription rules. It reports what could draw a lawsuit, a demand letter, or a fine. The market sells five quite different things under that one name, and most bad purchases come from buying the wrong category, not the wrong brand.
The five categories
1. Accessibility overlays (accessiBe, UserWay, AudioEye’s widget tier). JavaScript that adjusts how your pages present to visitors (contrast, focus order, screen-reader hints) without changing your code. Strengths: instant deployment, ongoing automatic adjustment. Limits: accessibility only, and no overlay is a recognized legal safe harbor. Sites running them are still named in ADA suits every year, so treat them as an assistive layer, not a compliance outcome.
2. Accessibility scanners (axe DevTools, WAVE, Lighthouse, Siteimprove’s a11y module). Developer-grade WCAG testing with precise element-level findings. Strengths: the standard instruments. Court-adjacent expert audits run on these engines. Limits: accessibility only, and raw findings without legal context: they tell you the contrast ratio failed, not what that has cost businesses like yours.
3. Consent & privacy platforms (OneTrust, Cookiebot, Termly). Cookie banners, consent records, policy generators. Strengths: they operate your consent flow, which a scanner can only inspect. Limits: they manage the mechanism they installed. They don’t audit the rest of the site, and a misconfigured banner from one of these platforms is itself a common finding.
4. Enterprise GRC suites (OneTrust’s full platform, Vanta, Drata). Governance, audit trails, SOC 2 / ISO certification workflows, vendor management. Strengths: if you need certifications, attestations, or HIPAA-grade programs, this is the category. Nothing below it substitutes. Limits: five-to-six-figure budgets and weeks of implementation; massively oversized for a small business’s website exposure.
5. Website compliance scanners (Complidar is one). Multi-regulation diagnostics: crawl the site, test accessibility, trackers, policies, and dark patterns together, and report findings with evidence. Strengths: one pass over the whole legal surface, priced for small businesses. Limits: a diagnostic, not a fix or a certification. The output is a prioritized to-do list for your developer and your attorney.
Six questions that sort the market
- Does its coverage match your actual risk? US small businesses are sued over accessibility, trackers, and auto-renewal far more often than over the things enterprise suites certify. Buy against the lawsuits in your category, not the longest feature list.
- Does it show evidence? A finding you can’t show a developer (the request, the cookie, the DOM node) or an attorney (the comparable case) is an opinion, not a finding.
- How does it handle uncertainty? Honest tools disclose confidence levels, false-positive rates, and failed checks. A report with zero hedges means the hedges were deleted, not resolved.
- What happens after the report? Overlays keep adjusting presentation; platforms keep operating consent; scanners hand you fixes. Know which follow-through you’re buying.
- Does the pricing model match your shape? Traffic-based subscriptions punish growth; per-seat punishes teams; per-audit and per-site pricing suit small portfolios. None is wrong. Mismatched is wrong.
- Can you leave? A diagnostic leaves you a report and fixed code. An overlay leaves with its script tag. A platform takes its consent records. Exit cost is part of price.
Red flags
- “Guaranteed compliant” or “lawsuit-proof.” No tool can promise either: compliance is a legal conclusion about facts, and only a court reaches it. Vendors selling certainty are selling the absence of a disclaimer.
- Invented dollar figures. If a tool shows you a liability number, ask where it came from. If the answer isn’t a citable public record, it’s theater.
- A perfect score from an automated scan. Automated checks catch a large share of issues, never all of them. Tools that don’t say so are optimizing for the screenshot, not the outcome.
- Pressure mechanics in the product itself. Countdown timers and fear-first dashboards from a vendor selling you consumer-protection compliance is a coherence problem.
Where Complidar fits, and where it doesn’t
Complidar is category five: a website compliance scanner for small businesses. One free scan covers the 22 checks that map to the suits small businesses actually face, every finding carries evidence and a cited settlement, and the full audit is $39. That’s the fit: operators who need to see their exposure this week, and agencies running diligence across a portfolio.
It is the wrong tool if you need SOC 2 or ISO certification workflows, HIPAA program management, a consent-management platform to operate your cookie banner, or a certified human accessibility audit for procurement. Categories one, three, and four exist for those, and we’ll say so when a scan suggests you’ve outgrown us.
