Question 1

What is the best Siteimprove alternative?

Accepted Answer

TestMu AI Accessibility Testing is the Siteimprove alternative to shortlist if you want accessibility checks that run in a hosted cloud and native app scans on 50,000+ hosted real devices, with published pricing. Deque axe suits teams that want the open-source axe-core engine and guided manual testing in Axe Auditor, and Level Access suits teams that want expert audits and VPAT documentation. For a wider list, compare these accessibility testing tools.

Question 2

How much does Siteimprove cost?

Accepted Answer

Siteimprove does not publish prices. Its pricing page offers a free site check, a free report and a demo request, and lists no plans or amounts. The TestMu AI pricing page lists the Accessibility plan from $159 a month, billed annually, for 750 scans a month, with higher tiers at 1,500 and 3,000 scans and a custom Enterprise plan. Prices as listed on October 27, 2026.

Question 3

Is Siteimprove free?

Accepted Answer

Parts of it are. The Siteimprove Accessibility Checker browser extension is free for Chrome, Edge, Firefox and Opera, and the Siteimprove toolkit has free checkers, including a single-page accessibility checker that emails results, a color contrast checker, a PDF checker and an accessibility statement generator. Siteimprove also offers a free Digital Insights Report delivered within 48 hours. The Siteimprove platform itself is sold by quote after a demo.

Question 4

What is an alternative to the Siteimprove Accessibility Checker extension?

Accepted Answer

Accessibility DevTools is the TestMu AI Chrome extension, and it is free. It runs Full Page, Partial Page, Multi-Page, Workflow and Keyboard scans, so you can check one component, a multi-step flow or keyboard access in the browser. The Siteimprove Accessibility Checker extension is also free and runs in Chrome, Edge, Firefox and Opera.

Question 5

Does Siteimprove provide VPATs?

Accepted Answer

Siteimprove's accessibility page says its specialists handle complex PDFs, VPAT work and training, and its professional services page says it can produce a conformance report. TestMu AI does not produce VPAT or ACR documents for customers. Its scan history and PDF or CSV exports are evidence you use to write your own, or to hand to an audit partner.

Question 6

Which WCAG versions do Siteimprove and TestMu AI check?

Accepted Answer

TestMu AI checks WCAG 2.2, 2.1 and 2.0 at levels A, AA and AAA, so a team targeting WCAG 2.1 AA can pick that level per scan. Siteimprove lets you set WCAG 2.2 as your site target, and its April 2024 help article said 1 of the 9 new WCAG 2.2 criteria was checked automatically and the other 8 manually.

Question 7

Can Siteimprove test mobile apps?

Accepted Answer

Siteimprove's help center describes Mobile Accessibility Testing: an installable Android app for in-app audits and an iOS tool that uses Appium with simulators or real devices. For mobile app accessibility testing, TestMu AI's App Scanner scans native Android and iOS apps on 50,000+ real devices, Appium scans run 15 iOS and 18 Android baseline rules plus 34 newer shared rules, and you can test with VoiceOver and TalkBack screen readers on real devices.

Question 8

How do I move from Siteimprove to TestMu AI?

Accepted Answer

Start with the pages you check today: scan them in the TestMu AI browser extension and compare the findings. Then set up accessibility monitoring for each site, with pages from a sitemap, CSV import or crawler and scans daily, weekly or monthly, and add automated accessibility testing to your Selenium, Playwright, Cypress or Appium suites so new issues are caught before release. Keep the PDF or CSV exports as evidence for your VPAT or audit work.

Question 9

What does Siteimprove offer beyond accessibility testing?

Accepted Answer

Siteimprove calls itself an agentic content intelligence platform. Its specialists handle VPATs and training, its professional services include manual audits, consulting and conformance reports, its PDF Remediation Agent generates alt text for document images, and its CMS Remediation Agent fixes issues in WordPress and Drupal. It also sells Search, Analytics and Content Strategy, and its free extension runs in Chrome, Edge, Firefox and Opera. TestMu AI does not produce VPAT or ACR documents; its focus is checks inside your test suites, native app scans on hosted real devices and published pricing.

Question 10

Can I use Siteimprove and TestMu AI together?

Accepted Answer

Yes. Teams that rely on Siteimprove for SEO, analytics, content strategy, PDF remediation or expert services can keep it for that work and use TestMu AI Accessibility Testing for checks inside their automated tests, native app scans on hosted real devices and screen reader testing. The two overlap in accessibility scanning, monitoring, checks inside test frameworks and native app checks.
