It's a Next.js app currently deployed on vercel with a Postgres DB running on supabase. Both are fairly scalable, but not in an optimal way in terms of costs. I'd either have to introduce a Pro pricing plan or get some donations from sponsors. The simple nature of the API would allow to heavily distribute this though, i.e. one could simply shard by progress bar.

Regarding the tight loops: Currently there is just basic rate limiting in place and the Python client batches updates by default. The app is not intended for short-lived progress bars with fast updates. These usually also don't have a good reason to be shared and live on the web. It's really much more useful for slowly updating, long running processes.
