You can always use mod_rails in development mode on Apache:
<VirtualHost *:80> ServerName myapp DocumentRoot /rails/myapp/public RailsEnv development <Directory "/rails/myapp/public"> Options FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> </VirtualHost>
Minus the ability to run an inline debugger, it works the same as mongrel or webrick, except multi-threaded and faster.
