Congrats on the launch and hitting HN's front page. Do you mind if I ask how your example site (multiplayer.dev) scaled?

I'm super curious about realtime multiplayer solutions (and I don't think I'm alone). But I find a great lack of info on what running this kind of app would cost. I come from the old-school hold-no-state, request->response->gtfo mentality, and I always have the _feeling_ that it'd be expensive to scale. Not just holding the websocket open, but how much effort do you expend parsing the WAL? How chatty is that kind of persistence mechanism? What other 'gotchas' are there etc.

I'd love nothing more than to dispel that vague feeling with data. I know it wouldn't come close to a full performance analysis, but throwing a few datapoints on a chart would help get a ballpark idea and tune my hype->action conversion.

I could nail down a pile of questions, but I'm sure you know better than I how to measure your own systems. But roughly I'm wondering: - how many users did you have? - how much traffic did you get? - how much would/did it cost to host on supabase? - how much resources did the database/realtime components consume?

Congrats again on the launch and have a nice weekend.
