Works great with Hostinger. I’ve had to toy with a few of the settings to get the optimized results I was looking for but that was easy to do.

Decent Optimizer
Tried it for image compression on my site. It does reduce size and helps a bit with loading. Setup was easy, too. But sometimes optimization feels a bit slow. Still ok for basic use.
