About
Srvr.dj is the last stop for hosting any website. No more configuring servers, no more scaling woes, no more downtime, and no more lock-in! Srvr.dj lets you write-or-rent every part of your deployment stack, press "launch" and never worry again. Ready-to-go software (e.g. Wordpress, OpenX, Joomla) and developer stacks (PHP, Rails, Django) are all available in the marketplace, open to developers who can write their own scripts and re-sell them, as well. Everyone wins, except the Downtime Monster.
