I've played around with a few different services and extensions for Keap. My personal opinion is that Graphly is next to oxygen on the scale of "gotta have it."

Graphly's reporting platform just keeps getting better and better, and this extension is just a bonus. It works much better than other extensions I've tried for Keap.

I've used this extension for almost 8 years now. I've been impressed with the updates along the way, especially the most recent update.
