ObjectCut vs ReSmush.it

ObjectCut is a background-removal API built on the open-source BASNet image-segmentation model, published exclusively as a RapidAPI marketplace listing rather than through its own developer portal — objectcut.com is just marketing, with the interactive docs, console, and pricing living at the RapidAPI listing page. Every call needs a RapidAPI key sent via the x-rapidapi-key header, and the listing is tagged freemium, meaning a free tier sits alongside metered paid plans. The underlying GitHub project (AlbertSuarez/object-cut) is still actively maintained, with commits as recent as July 2026.

ReSmush.it is a free, keyless image-optimization API — best known as the backend behind the ReSmush.it WordPress plugin — that accepts a source image URL and returns a JSON payload with the compressed image's URL plus original size, compressed size, and percent reduction. A live call against api.resmush.it needed no credentials and returned Access-Control-Allow-Origin: *, so it works directly from browser JavaScript. The plain http:// endpoint immediately redirects to https, so the service is https-only despite requiring no API key.
