Loupe checks and validates IIIF manifests: the JSON files that tell viewers how to present digital objects (A/V, books, artworks, maps, music scores) and where to find their media.

IIIF manifests can break in ways that are hard to spot: a missing comma, a misspelled field, an image URL that quietly 404s. Loupe identifies and flags these issues, all in your browser.

How it works: paste a manifest, load it from a URL, or open a file. It appears in a code editor, and Loupe checks it as you type. Problems are underlined where they occur and listed in a report; click any finding to jump to the exact spot in the JSON.

What it checks, in four layers:
- L1 Well-formedness - is it parseable JSON?
- L2 Spec conformance - does it match the IIIF Presentation API 3.0 structure?
- L3 Linking - do referenced URLs actually resolve?
- L4 Best-practice lint - valid but ill-advised (rights, labels, thumbnails)?
