Backlift, a Y Combinator-backed startup that’s launching today, describes itself as a back-end service for front-end developers. The service takes all of the work of setting up a server environment out of the equation and just lets front-end developers focus on their work. All a user needs is a Dropbox account – Backlift uses Dropbox as a file syncing service – and a text editor. With Backlift, a developer doesn’t need to know how to set up Rails,Django or node.js to get started.
