WebAIM's Accessibility Report: TYPO3 Stands Out from the Crowd!

Making your website accessible is no longer optional—it’s a necessity. It ensures everyone can access your content and services regardless of ability. Moreover, it’s a win-win situation for users, who get a seamless experience, and businesses, which benefit from increased reach, improved reputation, and legal compliance.

If you’re building a public-facing site today, accessibility is no longer optional—it’s business‑critical. Yet many teams still struggle to choose a content‑management system that won’t hold them back. Enter TYPO3. Thanks to a core built on WCAG principles and an active accessibility community, TYPO3 consistently outperforms other open‑source platforms for TYPO3 accessibility and TYPO3 barrierfree compliance. In this article you’ll learn:

• What the latest WebAIM “Million” report reveals about CMS choices
• How TYPO3’s native features reduce costly retrofits?
• Actionable steps to launch an accessible TYPO3 project today

So without further wait, let’s get started! What’s in the WebAIM report, and how does TYPO3 rank at the top among all CMS platforms!

• 27 % of the global population lives with a disability—roughly 1 in 4 visitors to your site.
• A shocking 96% of the world's top one million web pages remain inaccessible, leaving only 4% truly barrier-free for all users regardless of ability
• WCAG 2.2 is now the reference standard for most public‑sector and enterprise contracts.

Reports show that most websites fail to meet accessibility standards. But thanks to TYPO3’s built-in accessibility features, you can easily create and develop barrier-free TYPO3 websites.

Let’s first understand what accessibility means in TYPO3.

TYPO3 Accessibility means making websites easy for everyone to use, including people with disabilities. TYPO3 has built-in features that help users with different needs—like screen readers, keyboard navigation, or changing colors and text size—to access and use content in their own way. This helps create an inclusive website where everyone can find information, use services, and enjoy equal opportunities online. It removes digital barriers and makes the web better for all.

Accessibility helps remove digital barriers so that people with disabilities can easily use and enjoy your website. It makes your site more inclusive, improves the experience for all users, and allows more people to access your content and services. To truly focus on your audience, think about people with different needs—like visual, hearing, or movement-related challenges. Design your site to support them.

This helps you keep improving your site as it grows, making it better for everyone.

Each year, the WebAIM Million report checks the homepages of the world’s top one million websites to find common accessibility issues. In the latest study, TYPO3 stood out. It ranked fourth overall and was named the best-performing fully open-source CMS when it comes to accessibility. This means TYPO3 helps developers and site owners build more inclusive websites right from the start—without needing to rely heavily on extra fixes or tools.

Conclusion: Selecting TYPO3 gives your team an 18 % head start on compliance before you write a single line of code.

If you're designing to make your site accessible—and legally compliant—TYPO3 provides you with a good head start. It's not simply another CMS with a couple of accessibility add-ons. TYPO3 incorporates accessibility into its very foundations, making it a compelling option for organizations that value digital inclusion.

1. Standards-First Core That Just Works
Right out of the box, TYPO3 follows WCAG 2.2 AA guidelines across both its backend and frontend. Whether it’s the intuitive editor (powered by CKEditor 5), semantic HTML output, or ARIA landmarks for screen readers—everything is built to support accessibility without needing extra plugins. Even keyboard navigation is already in place, helping users with disabilities get around easily.

2. Smarter Permissions and Language Support
TYPO3 is made for complex, multilingual projects. It gives you detailed control over user permissions—right down to the field level—so editors can’t accidentally remove essential accessibility elements like alt text. Built-in fallback logic for languages ensures your content remains readable and accessible across different regions and users. Extensions that like Accesstive , T3AA are build to meet accessibility standards. 

3. Extensions That Go the Extra Mile
Need tools that make accessibility easier for editors? TYPO3’s extension library includes gems like the T3Accessibility Inspector, which can run live screen reader previews and contrast checks directly in the backend. If you're looking for more advanced options, the upcoming Accesstive Assistant widget uses AI to suggest and apply fixes without touching your code. It's an ideal solution for teams that want to stay compliant but don’t have deep technical resources.

4. Trusted at Scale—Proven by Governments
TYPO3 isn’t just a favorite among developers—it’s trusted at the highest levels. The German Government uses TYPO3 to power its Government Site Builder (GSB), thanks to TYPO3’s ability to pass BITV 2.0 audits—Germany’s strictest accessibility standard. If TYPO3 can meet federal-level expectations, it can certainly support your accessibility goals, too.

Keep Your Website Ready for the Future

TYPO3 is flexible, meaning your website can stay accessible even as new technologies and standards come out.

1. Follow Accessibility Standards (WCAG)

Use the Web Content Accessibility Guidelines (WCAG) as your checklist. TYPO3 makes it easier to meet these standards with its flexible framework.

2. Create Clear and Simple Content

Write in a way that's easy to understand. Use headings, short paragraphs, and simple words so everyone can follow your message.

3. Design with Contrast and Readability

Use high-contrast colors, readable fonts, and good spacing. Make sure that text is easy to see and read, even for users with low vision.

4. Add Alternatives for Media

Always add captions to videos, descriptions to images (alt text), and transcripts for audio content. This way, users who can’t see or hear well can still enjoy your content.

5. Make Navigation Easy

Design clear menus and simple paths for users to find what they need. Use consistent layouts and easy-to-understand links.

6. Test Your TYPO3 Website Regularly

Use accessibility testing tools to check your site often. Keep updating it to match new standards and user needs.
