We're working on a no-backend solution to help developers build great entirely client-side cloud apps. We provide a set of API's that can be used if you host on our platform or off it, and they work with any language. There are Restful API's for user authentication/signup, data management and more, as well as an easy way to get your app hooked up with other cloud API's like Twitter/Spotify/Facebook in a client-side app, which has been quite tricky until now.<p>We provide a Javascript library for these apps but you can also roll your own, since all our APIs are documented and are simple get/post requests.<p>It's quite a new space so there's only a handful of companies doing this; Hoodie is one of the others that is most notable.<p>Would love to hear what HackerNews thinks and happy to answer any questions.
