Accessibility (VPAT)
Nebbos is being built to Web Content Accessibility Guidelines (WCAG) 2.2 Level AA and Section 508 (Revised) conformance. This page is the summary view; the machine-readable VPAT 2.5 document is available on request.
Current status: the substrate meets WCAG 2.2 AA on the platform’s core operator surfaces. Some marketing surfaces and legacy pieces are still being audited. This page updates when a surface is fully conformant.
Standards covered
| Standard | Status |
|---|---|
| WCAG 2.2 Level A | Conformant across all in-scope surfaces |
| WCAG 2.2 Level AA | Conformant across the platform’s operator surfaces; marketing surfaces under audit |
| WCAG 2.2 Level AAA | Partial — targeted where practical |
| Section 508 (Revised) | Conformant on platform surfaces |
| EN 301 549 (European public procurement) | Substantially conformant; formal audit pending |
Surfaces in scope
| Surface | Coverage |
|---|---|
| Platform web app (dashboards, approvals, task tracker) | Full |
| Nebbos App (macOS, Windows) | Full — native platform accessibility APIs |
| Documentation (this site) | Full |
| Marketing site (nebbos.ai) | In progress |
| Cradle hardware (indicator LEDs, physical form) | Meets FCC accessibility guidance for hardware |
Assistive technology tested against
- Screen readers — VoiceOver (macOS, iOS), NVDA (Windows), JAWS (Windows)
- Keyboard-only navigation — full support across the platform
- Voice control — VoiceControl (macOS), Dragon NaturallySpeaking (Windows)
- Switch access — Switch Control (macOS, iOS)
- High contrast / colour inversion — supported via native OS palette
- Motion reduction — respected via
prefers-reduced-motionon all animated surfaces
Known limitations
We publish known limitations openly so they can be scored honestly:
- Some rich data tables lack a linear “read-across” mode in the current release; keyboard users can navigate them, but a screen-reader summary of large tables is on the roadmap.
- Complex chart types (sunburst, force-directed graph) have text-alternative summaries but not per-node navigation. Roadmap Q1 2027.
- The Cradle attestation ceremony requires a biometric enrolment step; alternative attestation flows for operators unable to use device biometrics are on the roadmap. Contact us if this affects deployment planning.
