    AI Samenvatting
    Sergii Steshenko
    CEO & Co-Founder @ Lengreo

    Web accessibility is no longer something businesses can leave until the final stages of a website project. It affects how people navigate, understand, and interact with digital content, whether they use a keyboard, screen reader, voice controls, or other assistive technology. The right company can uncover barriers that are easy to miss and turn accessibility into a practical part of the wider digital process.

    This list looks at web accessibility companies working across audits, remediation, testing, design, development, and ongoing monitoring. Their approaches vary, and that matters. Some focus heavily on technical compliance, while others bring accessibility into UX, content, and long-term website maintenance. The real value lies in finding a team that can do more than flag problems – they should help fix them without making the site harder to manage.

    Lengreo

    1. Lengreo

    At Lengreo, we include web accessibility in the design, development, and quality assurance process. We work on business websites, eCommerce platforms, landing pages, and custom web projects, adjusting layouts and interactions so people can use them with keyboards, screen readers, and other assistive tools. This can involve improving navigation, contrast, forms, page structure, buttons, links, and content presentation in line with WCAG requirements.

    We can also review an existing website and fix accessibility issues without rebuilding everything from scratch. Lengreo uses JavaScript and WordPress for much of its website work, so accessibility updates can be applied to both custom interfaces and content-managed sites. A small detail like an unclear form label or a menu that only works with a mouse can block part of the audience, which is why these checks are included alongside regular functional testing. After launch, we handle minor adjustments and ongoing maintenance as the website changes.

    Hoofdzaken:

    • Accessibility considered during design, development, and testing
    • Support for new websites and existing website updates
    • Work with WordPress and custom JavaScript projects
    • Accessibility improvements linked with wider UX and technical QA

    Diensten:

    • Website accessibility
    • WCAG-focused design and development
    • Keyboard navigation improvements
    • Screen reader and page structure checks
    • Accessible forms, menus, links, and buttons
    • Post-launch accessibility fixes and maintenance

    AccessifyLabs

    2. AccessifyLabs

    AccessifyLabs focuses directly on website accessibility, covering audits, technical fixes, consulting, training, and ongoing support. They assess websites against WCAG 2.2, ADA Title III, Section 508, EN 301 549, and other accessibility rules where needed. Their reviews combine automated scans with manual checks and assistive technology testing, which helps uncover problems that a basic scanning tool may miss.

    Once barriers have been identified, AccessifyLabs can work with design, development, and content teams to correct them. Their engineers handle semantic HTML, ARIA attributes, keyboard controls, contrast, focus indicators, forms, error messages, and complex components such as dropdowns or carousels. They also provide accessibility planning, internal policies, Webflow testing, legal risk support, and role-based training for developers, designers, writers, and QA teams.

     

    Hoofdzaken:

    • Automated, manual, and assistive technology testing

      The findings are used to outline which parts of the website need attention and how the business can move toward better accessibility. WSI also explains legal and technical requirements to teams that are still working out where to begin. Because accessibility sits alongside their web design, development, SEO, and digital marketing services, improvements can be applied without separating them from the wider website strategy. Regular reviews help identify new issues as pages, tools, and standards change.

      21Century.Tech

      16. 21Century.Tech

      21Century.Tech include web accessibility requirements within rapid website and web application development. Their senior engineers handle architecture, interface decisions, code review, testing, and final quality, while AI tools assist with code generation, documentation, and test coverage. For accessibility work, that setup can be used to improve semantic structure, keyboard controls, labels, focus states, and the behavior of interactive components.

      Because each release is reviewed by engineers before deployment, accessibility checks can be added to the same QA process used for functionality and security. 21Century.Tech is better suited to teams that need accessibility changes implemented as part of a broader build, feature release, or refactor. They also prepare CI/CD, tests, and technical documentation.

       

      Hoofdzaken:

      • Accessibility can be included in new builds and refactoring work
      • Senior engineers review code and final interface behavior
      • Automated tests are combined with human quality checks

      Conclusie

      Web accessibility services cover far more than a quick scan or a compliance badge. The stronger providers combine manual testing, technical remediation, assistive technology checks, design reviews, document accessibility, training, and ongoing monitoring. That mix matters because automated tools can find plenty of issues, but they cannot fully judge whether a person can actually complete a form, understand a page, or move through a complex interface without getting stuck.

      The right company will depend on the website, the team behind it, and how much work has already been done. Some businesses need a full audit and remediation plan, while others need accessibility built into development and maintenance from the start. Either way, the most sensible approach is usually the less flashy one: fix the underlying code and content, test with real users where possible, and keep checking the site as it changes.
