Nice tool at a fraction of the price of others in this space, but to be honest I'm not sure how it is a "better tool" - it's a code pad for coding interviews, but there are no rich features or any ways it distinguishes itself from others.
There are many gaps in the way code interviews are done, and especially with remote now I think there's a lot of ways you could have a tool which really differentiates itself in features and functionality. Good start though!
