very usefull when you want to keep an eye on your rig while away from it, you can even restart it, overclock, undervolt, check temps, and musch more while using the free edition. Honestly, i couldn't ask of anything more (except for a few things, but they are covered by the paid version)

Minerstat is simple to use no matter the size of your farm. My uptime is much higher and just having the front and backend tools available to customize my specific setups is what keeps me coming back. There are many choices which it comes to SaaS and mining I have tried them all. I must say minerstat does what I need it to best and it doesn’t it the best for me. I am able to run some of my rigs Linux based OS and some windows based w minerstat supporting it all for me. It works period.

Do not overlook minerstat when considering your mining options! The minerstat operating system with web control and monitoring is simply the best solution for gpu mining on dedicated rigs.
I appreciate the attention to a well thought out polished UI, remote access to all the controls and tuning without plugging in a monitor and of course the higher hashrate being on a linux based system compared to windows. It gives the user maximum control with very clear and reliable real-time data with the option to access the live console directly.
The whole service is so comprehensive I just wouldn't recommend any other method.
