reverse-image
IQDB
A combined reverse-image search across the major booru image boards. Danbooru, Gelbooru, Zerochan and others, covering tens of millions of tagged anime-style images. You give it an image or URL and it checks all the services at once; output is plain HTML with no API. The quickest way to find the catalogued, tagged source of an anime image when SauceNAO leaves doubt.

Por qué es útil y cómo funciona
IQDB is purpose-built for the anime and manga booru ecosystem: it searches Danbooru, Gelbooru, Zerochan, Konachan, Sankaku Channel, and several other tagged image boards in a single query, returning the closest matching post from each. It is most useful when SauceNAO does not return a confident result for an anime-style image, since IQDB's fuzzy visual matching can find a source even from a cropped or slightly edited version. Echo passes your image URL directly to IQDB and links you through to review the HTML results page.
Qué contiene
Tens of millions of tagged anime-style images drawn from seven or more major booru image boards, each independently maintained and updated by their communities.
