Fluffle is a reverse image search service for the furry community, designed to help find the source or similar versions of an image across multiple artwork platforms. Its core workflow is to accept an uploaded image, generate an image fingerprint, and compare it against indexed images. The project is open source under the MIT License and is available on GitHub.
Fluffle supports both web search and a public HTTP API. The reverse search endpoint is POST https://api.fluffle.xyz/v1/search, with images uploaded via multipart/form-data. The API supports JPEG, PNG, GIF, and WebP, with a maximum file size of 4 MiB per image and a maximum image area of 16MP. Parameters include whether to include NSFW results, target platforms, result limit, and whether to create a permanent link. Results include match score, match type, source platform, original location, thumbnail, and attribution information. Covered platforms include Fur Affinity, Twitter, e621, Weasyl, Furry Network, DeviantArt, Inkbunny, and Bluesky.
The documentation provides image preprocessing recommendations, Python examples, response schemas, and a fairly complete list of error codes, making it developer-friendly for integration. However, the crawled text clearly notes that this API documentation is legacy, and that new projects should use the newer documentation on readme.io. On privacy, uploaded images are stored only temporarily by default: they are deleted immediately after a fingerprint is generated, and fingerprints and search settings are not retained. However, if a permanent link is created, the image and results are stored indefinitely. The site uses no cookies and relies on Cloudflare Web Analytics.
The available text does not disclose paid plans, SLAs, rate limits, or enterprise support. Only a Ko-fi link is visible, so it is best viewed as a free/donation-supported project. The service runs behind Cloudflare, and the documentation notes that some errors may return Cloudflare HTML rather than JSON, so client implementations should account for retries and exception handling.
Its strengths are being open source, having clearly defined vertical data sources, and offering transparent API details. It is suitable for community bots, gallery tools, repost/source tracing, and source lookup for furry artwork. Its limitations are relatively weak general-purpose image search capabilities, limited commercial assurance, and additional maintenance uncertainty due to the legacy documentation notice.
The crawled text does not provide information about access from mainland China, local payment options, or mirrors. Because it uses Cloudflare and depends on external art platforms, real-world availability may vary depending on the network environment. Alternatives include Google Lens, TinEye, SauceNAO, Yandex Images, and Ascii2D.
