ShareX is a free and open-source application that enables users to capture or record any area of their screen with a single keystroke. It also supports uploading images, text, and various file types to a wide range of destinations. Its best trick is the custom uploader: a small .sxcu config that points ShareX at any endpoint. I point it at this site — so my screenshots upload here and every link I share carries my own domain.
A custom uploader is just JSON: the endpoint, an auth header, and how to read the hosted URL out of the response. Build one for any endpoint with the config builder below — it ships a ready preset for this site’s own (token-gated) uploader.
