tus is a new open protocol for resumable uploads built on HTTP. It offers simple, cheap and reusable stacks for clients and servers, solving the problem of unreliable file uploads once and for all. It supports any language, any platform and any network.
People are sharing more and more photos and videos every day. Mobile networks remain fragile however. Platform APIs are also often a mess and every project builds its own file uploader. There are a thousand one-week projects that barely work, when all we need is one real project. One project done right. We are the ones who are going to do this right. Our aim is to solve the problem of unreliable file uploads once and for all. tus is a new open protocol for resumable uploads built on HTTP.

Perhaps that is because no-one has managed to solve it yet. But we're going to give it our best shot.
