Feedback needed

NOT ADS! Hope admin lets this to be posted
I am trying a new project and would like you to help. I created an uptime.onl for tracking one’s web site stability.
I am glad to provide a lifetime subscription for free for first active 50 users registered in a beta version, providing every minute check for up to the 20 links, extended to a full uptime.onl version later.
Yes, it is still a beta version, so I would appreciate any feedback you can give on the product for improving the efficiency.
