Whilst I cannot attest to the day-to-day functionality of its primary use - social posting- I wanted to get my review in after being very impressed so far. I have tried a number of SaaS tools and php scripts with this kind of functionality, including Postoplan, Chatpion and Stackposts; I was most impressed by the interface with Followr; it was clean, very inviting and easy to navigate. It looks like it's going to make social media management a breeze.
I went all-in (with AppSumo's 60-day refund period, etc.) to get the white label functionality. I am not disappointed. The setup was straightforward - You enter the necessary branding details, and an embed code is generated. You can embed the code anywhere you can host a static site. I tried Cloudpanel, Editor.do (also on AppSumo), Bunny CDN. I finally installed it on a cheap Hostinger cPanel server because it is just a (white labelled) gateway to Followr, so you don't need much in the way of resources. I'm perfectly happy with this as an alternative to CNAME, as it has exactly the same functionality. I am pretty sure I will be keeping this purchase! Many thanks
