AccessiScanSiteimprove is the name most people reach for when they think “website accessibility platform.” It's a strong product. It's also priced and built for large organizations — which is why so many small businesses and agencies bounce off it. Here's an honest, side-by-side look at Siteimprove and AccessiScan so you can pick the one that fits, not just the one with the biggest brand.
Disclosure: AccessiScan is our product. We'll keep this fair — Siteimprove is genuinely good at what it does, and for some teams it's the right call. We'll tell you when.
The short version
- Choose Siteimprove if you're a large organization with a dedicated accessibility program, budget in the five figures, and you want accessibility bundled with broader content QA, SEO, and analytics across thousands of pages.
- Choose AccessiScan if you're a small business, a freelancer, or an agency that needs an accurate WCAG 2.1 AA audit, a prioritized fix list, and a client-ready report — at a price that doesn't require a procurement cycle.
Price
This is the biggest practical difference. Siteimprove uses enterprise contracts that typically land in the $15,000–$50,000/year range, quoted through sales. AccessiScan is self-serve: a free scanner with no account, Pro from $39/month, and a one-time audit plus Legal Evidence Pack for $149. For a team that needs to scan a site and fix it — not run a company-wide governance program — that's the difference between a card payment and a budget request.
What you actually get
Both run automated WCAG 2.1/2.2 checks and flag the same categories of machine-detectable issues (contrast, alt text, labels, structure, keyboard traps). Honest framing applies to both: automated scanning catches roughly 30–40% of WCAG success criteria; full conformance needs manual testing. Neither tool, on its own, makes a site “compliant” — and you should be wary of any vendor that says it does.
Where they diverge is the surrounding platform. Siteimprove gives you dashboards, role management, content QA, and analytics built for ongoing governance at scale. AccessiScan stays focused on the audit itself and adds the thing small teams keep asking for: a dated, verifiable record — a timestamped, SHA-256 hash-signed audit with a public verification page, a 30/60/90-day remediation plan pre-filled with your issues, a draft accessibility statement, and a demand-letter response template. It documents conformance status and good-faith effort; it is not legal advice.
Speed to a usable result
With Siteimprove you typically book a demo, get a quote, and onboard. With AccessiScan you paste a URL and get a result now, or buy the $149 audit and have the report emailed within the hour. If you're responding to a demand letter or a procurement deadline, that timeline difference is the whole point.
When Siteimprove is the better choice
We mean this. If you manage thousands of pages across many teams, need accessibility folded into a broader content-governance platform, and have the budget, Siteimprove is built for that and does it well. AccessiScan is not trying to be an enterprise governance suite — it's trying to get a specific site audited, documented, and fixed without the enterprise overhead.
Try it in 60 seconds
The fastest way to compare is to run your own site. Scan it free — no account — and see the issues for yourself. If you need the dated audit + Evidence Pack, get it here for $149. See also our honest roundup of WCAG scanners and what a WCAG audit costs.
