Deque Systems provides a comprehensive digital accessibility platform to help organizations build, test, and maintain accessible web and mobile experiences. It combines AI-powered automated testing tools, guided manual testing, expert audits, and role-based training to help teams identify and fix accessibility issues throughout the development lifecycle.
Maintaining digital accessibility compliance can be complex and resource-intensive. Deque helps organizations reduce the cost and effort of accessibility by catching issues early in the development process, prioritizing fixes, and tracking compliance over time. It empowers developers, designers, and quality assurance teams to create inclusive products that meet standards like WCAG.
Deque is ideal for development teams, QA professionals, accessibility program managers, and compliance officers in enterprises, government agencies, and organizations that need to meet regulatory requirements. It is particularly beneficial for teams with existing accessibility expertise that need to scale their efforts and integrate testing into their current workflows. It may be overkill for individuals or small teams looking for a simple, one-off accessibility check.
Deque's tools can be used to conduct a full-site accessibility audit, provide documentation for VPAT (Voluntary Product Accessibility Template) reports, enable developers to fix issues directly in their IDE, and set up ongoing monitoring for compliance. For example, a government agency can use Deque to ensure its public-facing portals meet legal standards, while a software company can integrate its axe DevTools into its CI/CD pipeline to prevent new accessibility regressions.
