It has free features that allow for a limited amount of images optimized but there's also an API and a paid subscription. I like that it's not limited by the number of websites. I also like that it integrates fully with WP-Rocket. Review collected by and hosted on G2.com.
I don't see any drawbacks to it. It's always worked well and is pretty full-featured. There are free options on the market and this one does provide some free compressions. Review collected by and hosted on G2.com.
