What to expect from Siteimprove

Siteimprove is widely recognised as an all-in-one digital governance platform that includes accessibility monitoring among other capabilities. Typical buyer expectations are:

• Automated site-wide crawls that surface failures and provide prioritised remediation tasks.
• Dashboards and reports intended for teams (developers, content owners and compliance officers).
• Enterprise-focused features such as role-based access, SLAs and integrations with CMS, issue trackers and CI/CD pipelines.

What we could not verify publicly in detail: exact WCAG success criteria coverage, per-check false positive rates, current pricing tiers and any recent change history. Ask Siteimprove for a current VPAT or accessibility conformance report, a full list of checks mapped to WCAG, and customer references in your sector.

What to expect from DubBot

DubBot is positioned as an automated accessibility testing tool. Buyers typically look to tools like DubBot to run fast scans, produce issue lists that developers can act on, and integrate checks into development workflows.

• Automated scans that identify common WCAG failures and technical issues.
• Exportable reports or issue lists for remediation workflows.
• Potential integrations with CI/CD and source control (confirm with vendor).

What we could not verify publicly: a comprehensive list of supported WCAG success criteria and levels, the availability of a VPAT or accessibility conformance report, official integration list, pricing, and up-to-date review ratings. We recommend requesting a product datasheet, demonstration of the scanner on representative pages, and sample reports before procurement.

Feature comparison: testing scope, standards and integrations

When comparing automated accessibility tools, apply the same checklist to both vendors. Below are the standard areas to verify directly with each provider.

• Scope of automated checks: which WCAG success criteria the scanner tests and which it cannot test (e.g., keyboard navigation, meaningful sequence often require manual review).
• WCAG versions and levels: whether the tool maps findings to WCAG 2.1/2.2 and levels A/AA/AAA and whether it provides a VPAT/ACR.
• Manual testing support: guidance, checklists and enablement for manual or assisted testing workflows.
• Integrations: CMS, issue trackers (Jira, Azure DevOps), CI/CD pipelines, and developer tooling.
• Reporting & governance: dashboards, prioritisation, progress tracking, audit logs and export formats.

Note: automated testing cannot prove full WCAG compliance. Any vendor claim to the contrary should be clarified and substantiated with a VPAT and a description of manual testing processes.

Pricing comparison

Public pricing details were not consistently available for either product at the time of writing. Typical models in this category include subscription tiers based on number of domains, pages crawled, or user seats, plus optional professional services for auditing and remediation.

Ask each vendor for:

• a detailed quote based on your domain count and traffic;
• what’s included in each tier (scan frequency, historical data retention, number of users);
• professional services rates for initial audits and remediation support;
• trial or proof-of-concept terms and data retention/ownership.

Ratings and user feedback

Independent review site scores and user counts change frequently. We could not verify up-to-date aggregate ratings for DubBot from major marketplaces at the time of writing. For Siteimprove, public product resources and customer case studies are generally available; verify current review counts and dates on G2, Capterra or similar sites during procurement.

When evaluating reviews, look for repeated praise or concerns about:

• accuracy of automated findings (false positives/negatives),
• quality of support and onboarding,
• ease of integration with existing workflows, and
• reporting usefulness for non-technical stakeholders.

Ease of use and support

Ease of use varies by audience. Checklist items to confirm with each vendor:

• demo with your site or sample pages, so you see scan results and remediation steps;
• onboarding and training options (self-serve docs vs consultancy-led onboarding);
• support SLAs and account management for enterprise customers;
• developer-friendly exports (JSON, CSV, direct Jira/Azure integration) and API access.

If a vendor cannot demonstrate developer workflow support or a clear remediation path, expect higher internal costs to operationalise the tool.

Which one is right for you?

Choose based on validated fit rather than brand alone:

• Large organisations needing a governance platform plus site analytics should prioritise vendors that demonstrate enterprise integrations, dashboards and professional services.
• Development teams that want fast CI/CD checks should prioritise tools with robust API, CLI and issue-tracker integration.
• Organisations focused on legal compliance should request a current VPAT/accessibility conformance report and evidence of manual testing processes.

Because public information about DubBot’s coverage and reporting is limited, teams considering DubBot should request a live trial, sample reports mapped to WCAG, and references before signing a contract. For Siteimprove, confirm exactly which checks are automated and request a VPAT/ACR and integration list aligned to your tooling.

Verdict

We cannot declare a definitive winner without current, vendor-supplied documentation and a hands-on trial of both products for the buyer’s specific site and workflow. Practical next steps: request a VPAT or accessibility conformance report from each vendor, run a proof-of-concept on representative pages, and compare results, false-positive rates and developer integration ease. Use those outcomes—rather than marketing claims—to decide.

FAQs

Can automated tools like Siteimprove or DubBot make my site fully WCAG compliant?

No. Automated tools cover only a subset of WCAG success criteria. Manual testing (keyboard, screen reader, cognitive checks) and expert review are still required.

How do I verify a vendor’s WCAG coverage?

Ask for a VPAT or accessibility conformance report, a mapping of checks to WCAG success criteria, sample scan reports and a list of known limitations.

Should I run both tools in parallel?

Running two automated scanners can be useful to compare coverage and false-positives, but it increases review workload. Start with trials and a mapping exercise to see which tool finds the issues most relevant to your site.

What integration questions should I ask?

Confirm API access, CI/CD or CLI support, direct issue tracking integrations (Jira, Azure DevOps), and whether the tool can be run on private/staging environments.

What if a vendor claims “full compliance”?

Request written evidence: a VPAT/ACR, detailed scope of automated checks, and descriptions of manual testing processes. Be sceptical of any claim that automation alone certifies legal compliance.

Who should I involve in the trial?

Include a developer, a content owner, an accessibility lead (or consultant) and a product owner to validate results across technical and editorial dimensions.

Note: This guide highlights where public documentation was available and where it was not. Always validate vendors with up-to-date product documents, demos and references prior to procurement.
