Scores zijn een relatief, geautomatiseerd signaal op basis van axe-overtredingen per pagina (axe draait op elke pagina; Alfa wordt bemonsterd en apart gerapporteerd). Geautomatiseerd testen vindt slechts ~⅓ van de barrières — gebruik scores om te vergelijken en de richting te volgen, niet als geslaagd/gezakt.

Recurring patterns across domains
Geblokkeerde doelen (1)
Deze sites gaven de scanner alleen "toegang geweigerd"-antwoorden, dus er kon geen toegankelijkheids- of duurzaamheidsdata worden verzameld. Dit is doorgaans een WAF of botmanager die geautomatiseerd verkeer blokkeert, geen scanfout. Zie WAF-ALLOWLIST.md voor hoe de scanner op de toelatingslijst kan worden gezet.
- hhs.gov — HTTP 403 (2026-W40)
Hulpmiddelen
- URL-foutopzoeker — plak een URL of URL-fragment en exporteer alle toegankelijkheidsbevindingen voor die pagina als JSON, CSV of JIRA-klare Markdown.
Waarom dit bestaat
Continue meting is beter dan eenmalige audits. Dit register volgt of elke site na verloop van tijd toegankelijker en lichter wordt, met axe-core en Alfa (de opensource-engine achter Siteimprove) voor toegankelijkheid, en paginagewicht met CO₂-schattingen van Sustainable Web Design voor duurzaamheid. Alles hier is open: de scanner, de data en de rapporten.
This data is also available beyond the web page: a read-only JSON API (no auth, no server), a machine-discovery API catalog, and for coding agents an llms.txt guide plus a local MCP server.
