As a heavy (and admittedly very proud) Tumblr user, I frequently get asked "Can I self-install Tumblr on my own webspace?" and have answer "No". That's not a big deal to most people - it's possible to use custom domains with Tumblr, customise the look and feel of your site and more directly from within Tumblr - but for the slightly more technical, it can be a deal-breaker.

If you're wanting to self-host something similar, however, Chyrp is a light-weight blogging engine that allows you to self-host a Tumblr-style blog, right down to the specific Tumblr post options such as Link, Quote, Text, Video and Image. It's also pretty extensible, with extra modules and 'feathers' available for users to add and enhance their sites.

Chyrp certainly isn't for the average Joe, looking to set up a blog without any fuss - however if you're looking for the style and speed of a Tumblog, and want to delve into the code to customise its design and function, it might be right up your street.

Chyrp is available under the GNU General Public Licence (version 3) for your hacking pleasure, and requires a PHP5 / mySQL or SQlite compatible webhost.
