I just tried it and it works perfectly. The color scheme and font size could be touched up to look better. Just out of curiosity, is $10/month enough to cover the (unlimited) API cost? Do you estimate how many percentage of your users will use more than $10 API fee each month?

Thanks so much for trying it out! The realtime API is actually very cheap especially for short connections, for each user who uses it 30 minutes a day every day in a month it costs me ~$5 and I assume the average user is going to use it way less than that (although i have 0 users right now haha)
