Hi, one of the authors here. Indeed, resumable uploads are not a thing we invented. Nevertheless, we think it&#x27;s handy to have a document describing the approach and client and server implementations. Amazon, Dropbox and Google offer some in the way of describing how they do it, but nothing to address the problems that wider audience could encounter, and no platform for collaboration to make it better. tus was built under MIT and on GitHub and will continue to evolve through contributions from the community (although we consider that what we cemented into 1.0.0 ready for adoption)
