Must-have app if you care about speed and conversions. Our site performance improved almost immediately, and the team helped us optimize things we didn’t even know were slowing us down. Easy to use and great support.

Good experience so far. It improved our site speed and helped clean up some performance issues. It’s not 100% ‘set and forget’—we needed a bit of support—but the team was quick and helpful. Overall very happy with the results.
