Resumable File Uploads

Users want to share more and more photos and videos. But mobile networks are fragile. Platform APIs are a mess. Every project builds its own file uploader. A thousand one week projects that barely work, when all we need is one real project, done right.

We are going to do this right. We will solve reliable file uploads for once and for all. A new open protocol for resumable uploads built on HTTP. Simple, cheap, reusable stacks for clients and servers. Any language, any platform, any network.

It's probably an impossible dream. No-one has managed yet. But we're going to give it our best shot. Join us on GitHub and help us make the world a better place. No more lost cat videos!
