Drop a URL into WAVE and it overlays every accessibility error it can detect on the page itself, a workflow WCAG testers have leaned on since 2001. The online checker and browser extensions are free; only the API for automated scanning at scale carries a price. There is no vendor in the usual sense: WAVE is run by WebAIM, a nonprofit institute based in Logan, Utah, at Utah State University.

Why choose Rocket Validator over WAVE?
The decisive argument is data jurisdiction. WAVE is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Rocket Validator removes that overhead. As a Spain-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
