Checks a domain's iOS apple-app-site-association and Android assetlinks.json in one call and returns a score, a grade and findings with stable codes, JSON paths and Apple/Google documentation links. Redirects are reported, not followed, as both platforms require. An offline validate endpoint checks drafts before you publish. Format and serving checks only: it does not verify signing certificates, that an app exists, or OS routing.





Hi, broken association files fail silently on the device, so I made a checker that looks at what the platforms actually require: HTTP 200, no redirects, JSON content type, size limits, TeamID.BundleID app IDs, components and paths, assetlinks relations and SHA-256 fingerprint format. platform can be ios, android or both. Scope is stated plainly: format and serving only, no certificate or app verification, and Apple's CDN caching delay is not reflected. Feedback welcome.
