Hostr is a project I started almost ten years ago when I set out to learn web development. Since then it's seen over 100,000 signups and served up over 2 billion file downloads.
It has been through many iterations, but in its current incarnation Hostr uses [Koa](http://koajs.com/) for the backend, [Angular](https://angular.io/) and [JSPM](http://jspm.io) for the frontend, and [Babel](https://babeljs.io/) for both.
See [`.envrc.example`](.envrc.example). Copy it to `.envrc`, modify and `source .envrc` for development. [direnv](https://github.com/direnv/direnv) is pretty nice for doing this automatically when you `cd` into your work directory.
My primary motivation is to get to work on Hostr in public. Contributions are welcome and all Javascript is Apache licenced, however the brand is not. The brand includes the name, logo images, CSS and marketing HTML.
