I feel like people forget just how fast a single machine can be. If your database is SQLite the app will be able to burn down requests faster than you ever thought possible. You can handle much more than 23 req/day.
In the not-too-distant past I was handling many thousands of DB-backed requests per hour in a Python app running plain PostgreSQL.
You can get really, really far with a decent machine if you mind the bottlenecks. Getting into swap? Add RAM. Blocked by IO? Throw in some more NVMe. Any reasonable CPU can process a lot more data than it's popular to think.
Anytime someone talks about scale I remember just how much data the low mhz CPUs used to process. Sure the modern stuff has nicer UIs, but the UIs of the past where not bad, and we a lot of data was processed. Almost nobody has more data than what the busiest 200mhz CPU on 1999 used to handle alone, so if you can't do it that isn't a scaling problem it is a people problem. (don't get me wrong, this might be a good trade off to make - but don't say you couldn't do it on a single computer)
