Web Accessibility Complaints Kept Climbing in 2025. Build Vendors Are Increasingly Exposed.
As web accessibility disputes rise, contracts and complaints increasingly reach past the brand to the agency or developer that built the site.
Web accessibility disputes kept climbing in 2025 — by most trackers’ counts, filings rose sharply year over year — and the agencies and developers who build sites are increasingly exposed, not only the brands that own them. For studios that have treated accessibility as the client’s problem, that is a meaningful shift in risk.
Why vendors are being named
Contracts increasingly assign responsibility for conformance to whoever built and maintains the site. A complaint typically lands on the business that owns the site, but the contract terms decide who ultimately carries it — and clients increasingly look upstream. A studio that shipped a component library with inaccessible patterns baked in is, in effect, distributing that liability across every site that uses it.
What conformance actually requires
The reference standard remains the Web Content Accessibility Guidelines, with Level AA the practical target for most public sites — WCAG 2.1 in most current legal and contractual references, though 2.2 was finalized in late 2023 and is increasingly cited. The recurring failures are unglamorous: insufficient color contrast, missing form labels, keyboard traps, and unlabeled interactive controls — precisely the kind of defect a design system can fix once and prevent everywhere, or propagate everywhere if it gets them wrong.
The studios treating accessibility as a system property rather than a per-project checkbox are the ones least likely to appear in next year’s filings. For everyone else, the trend line is a warning worth pricing in.
