A Web Server Called Ebb

Ebb aims to be a small and fast web server specifically for hosting dynamic Ruby language web applications.

It is a binding to libebb


The Ruby binding is available as a Ruby Gem. It can be install by executing

gem install ebb

If you want SSL support you must install GnuTLS. Ebb has no other dependencies.


Use Ebb.start_server()


(these stats are out of date)

Because Ebb handles most of the processing in C, it is able to do work often times more efficiently than other Ruby language web servers.


Ebb-Ruby can handle threaded processing better than the other 'evented' servers. This won't be of any benefit to Rails applications because Rails places a lock around each request that wouldn't allow concurrent processing anyway. In Merb, for example, Ebb's thread handling will allow Ebb instances to handle larger loads. More
