Free FiveM server status checker
Enter any cfx.re join code and see whether that server is online, how many players are on it right now, and what its slot count is. No account, no sign-up, nothing to install.
Live from Cfx.re, cached for a minute. This is the same lookup the template ships with.
Where to find a join code
It is the six or seven characters at the end of a cfx.re/join/ link. Connect to your own server, press F8, and the connection line has it. You can paste the whole link here, not just the code.
