What do you think of Installatron? I'm quite impressed with what I see from the demo.

Anyone have it installed? How would you say it compares to Fantastico?

Installatron has worked better than Fantastico and been better updated for a long time. Lots of threads here on it.

It kicks Fantastico's but. Fantastico is barebones, but Installatron has so much power. You can install, upgrade, backup, and revert. You can also customize the installs it already has and add scripts to the install library so you can add scripts to your customers. It's a great piece of software and they let you install it free for one domain without limits.

works great for me :)

Can we use two of them on one server ?

I've never tried it, but I believe you can.

They offer a one domain license for free and have server licenses for unlimited domains with a couple of pricing options.
