I have been using MainWP to monitor, update, and manage my clients websites since 2013. I love this software. At any given time, I usually manage between 70-100 WordPress websites.
In 2012, I was still logging into each site one at a time, every day, to check for updates. Finding MainWP was a game changer! At the time, my colleague found a different WP management software and tried that one instead. That one ended up going out of business, and they also switched over to MainWP.
While I use the free version, my colleague bought the paid version, so I have access to both of them in the course of my daily work. The MainWP team provides excellent support, no matter which version you have. They truly are professionals in every way. I hope they stick around for a long time to come.
Thank You MainWP staff!! You do a great job. I am SUPER IMPRESSED with your company!
