• Human expert audits and assistive-technology user testing alongside the tooling.
• Legal and VPAT support for organisations under compliance pressure.
• Covers web, mobile and desktop applications.

• Guided manual testing addresses the two thirds of WCAG that scanners cannot.
• Findings come with concrete code-level remediation advice.
• Deque's accessibility expertise is the deepest in the industry.

• Expensive, services-heavy engagement model.
• The UserWay overlay heritage is contentious — automated overlays are widely criticised by accessibility practitioners.
• Not a self-serve developer tool.

• Per-seat pricing adds up across a large engineering organisation.
• The free extension is good enough for many teams, blurring the upgrade case.
• Enterprise deployment needs process design, not just a licence.
