Bubble is a no-code platform for building full web applications with databases, workflows, and user authentication - all without writing code. While Bubble empowers non-developers to ship complex applications, its generated HTML and JavaScript-heavy architecture create accessibility challenges that users have limited ability to fix. Under the EAA, Bubble applications serving EU consumers must meet EN 301 549 requirements.
Common Bubble accessibility issues
Generated HTML lacks semantic structure
Bubble generates its own HTML from the visual editor, producing deeply nested div-based layouts with inline styles. The output lacks semantic elements - no nav, main, article, or section landmarks - making page structure invisible to screen readers.
Custom form elements without native accessibility
Bubble's form inputs are custom-rendered elements rather than native HTML form controls. These custom elements often lack proper label associations, miss native form validation, and don't expose the expected roles and states to assistive technology.
Dynamic content loading without screen reader announcements
Bubble applications heavily rely on dynamic data loading - repeating groups, popups, conditional elements, and search results all update without page reloads. These changes are not announced to screen readers via ARIA live regions.
Repeating groups lack list semantics
Bubble's repeating groups (used for data lists, search results, feeds) render as stacked divs rather than proper list markup (ul/ol with li elements). Screen readers cannot communicate how many items exist or where the user is in the list.
Popup and overlay focus management
Bubble's popup element is commonly used for modals, confirmations, and detail views. These popups typically don't trap focus, can't be dismissed with Escape, lack ARIA dialog roles, and don't return focus to the trigger when closed.
Colour and contrast controls are limited
Bubble's styling system uses absolute colour values set per element. There's no global theme or design token system, making it difficult to audit and correct contrast ratios across an entire application.
How Lumi works with Bubble
Lumi scans your deployed Bubble application in its fully rendered state, interacting with dynamic elements, popups, and repeating groups. Our five engines detect issues in Bubble's generated markup, custom form controls, and client-side routing. Monitor continuously to catch regressions from editor changes and plugin updates.
Bubble-specific WCAG gotchas
Limited HTML control means limited fixes
Bubble doesn't expose the underlying HTML for direct editing. Accessibility fixes are constrained to what the Bubble editor and plugin system allow, meaning some structural issues cannot be fixed without platform-level changes by Bubble.
Plugins extend functionality but not accessibility
Bubble's plugin marketplace adds features like rich text editors, maps, and charts. These plugins generate their own markup which is typically untested for accessibility and outside the app builder's control.
SPA architecture means no natural page transitions
Bubble applications are single-page apps - navigation between 'pages' happens client-side without browser page loads. Screen readers receive no automatic notification when the view changes.

Frequently asked questions
Can Bubble apps be made accessible?
Bubble has added some accessibility features including alt text fields, ARIA label inputs, and heading role settings. However, fundamental structural issues in Bubble's generated HTML mean full WCAG 2.2 AA compliance is very difficult to achieve on the platform.
Does the EAA apply to Bubble applications?
If your Bubble application provides services to EU consumers - including SaaS tools, marketplaces, booking platforms, or financial services - the EAA applies. The no-code nature of the platform does not exempt the application from accessibility requirements.
What accessibility features does Bubble offer?
Bubble has introduced ARIA label fields, alt text inputs, heading role settings, and tab index controls. These are useful but cover only a fraction of WCAG requirements. Structural issues like semantic HTML, focus management, and live region announcements remain largely outside user control.
Should I consider moving off Bubble for accessibility compliance?
If your application has strict accessibility requirements - particularly for regulated sectors like banking, healthcare, or government - Bubble's platform-level limitations may make full compliance impractical. Evaluate whether the accessibility gaps can be acceptably mitigated within Bubble before committing to the platform for a compliance-sensitive project.
