Old School CFW

The window to join Old School CFW is 18:00–02:00 UTC, when it averages 44 concurrent players — well clear of its 31-player round-the-clock average. It bites hardest at 22:00 UTC, averaging 56. Its longest quiet stretch is 03:00–18:00 UTC, averaging 23 players — thin by its own standards, but still a running city rather than an empty one.

You can walk straight in: when anyone is on it, it averages 29 players against 128 slots (23% full), and even its busiest moment of the week, 87 players, left 32% of the server free. Day to day it barely moves: across those 7 days its daily averages stay within 66% of each other, so this is a settled population rather than a spike.

That puts Old School CFW ahead of 97% of the 42,379 FiveM servers ViceHub tracked consistently this week, ranked on peak concurrent players. That is measured from our own five-minute checks, not from anything the server claims about itself.
