One of the most recommended hosters [0] offers a 90 EUR/month plan just for up to 50 concurrent users! What I joke! This is like an instance fir my extended family and friends!
Also, in the 'about the plans' section of that page, under 'Concurrent Requests' and 'Users and Active Users' you have more details. But one can think of concurrent requests limit as actions occurring simultaneously (eg: 50 people clicking a button at the exact same time). Even on the rare occasions when that happens, the actions are queued and take a couple more seconds to process.
