FiveM server.cfg Generator

server.cfg is the plain-text configuration file every FiveM (and RedM) server reads on startup. It sets your server name, network endpoints, player limit, OneSync mode, license key, security convars, admin permissions, and the list of resources to start. The server runs each line as a console command from top to bottom, so order matters: endpoints and core convars come first, then your resources.

Copy or download the file, save it as server.cfg in your server data folder (next to the resources directory), then paste your real license key from portal.cfx.re over "changeme". With txAdmin, point Settings, FXServer, CFG File Path at the file. Without it, start FXServer with the file, for example FXServer.exe +exec server.cfg on Windows or ./run.sh +exec server.cfg on Linux. Everything in this tool runs in your browser, nothing is uploaded.

Yes. Pick FiveM Enhanced at the top. Enhanced, in early access since July 2026, always runs OneSync, supports only the latest game build (or 1 for the base game), keeps pure mode on, and replaced Mumble with a built-in voice server you start with voice_internal. The generator leaves out the lines Enhanced dropped, like onesync and sv_endpointprivacy, offers the new sv_syncTickRate, and starts only the base resources Cfx.re’s Enhanced recipe uses. The server runs as cfx-server.exe instead of FXServer.exe, and Tebex escrowed resources do not run on it yet.

txAdmin recipes give you a working starting file for a specific framework. This generator builds the file around your own choices instead: FiveM, FiveM Enhanced or RedM, a locked game build, OneSync mode, RCON left off unless you deliberately enable it, sv_endpointprivacy on to hide player IPs, sv_scriptHookAllowed off for live servers, an optional strict identity check, your admin ACE lines and your own resource list, with a comment on every line explaining what it does.

txAdmin starts FXServer with OneSync already set from its own settings (Settings, FXServer, OneSync), so it comments out any onesync line it finds in server.cfg and warns you. Pick txAdmin at the top of this tool and the file leaves the line out and says where to set it. Running FXServer yourself? Pick Plain FXServer and the file gets set onesync on.

Tick the allowlist box to add sets sv_appearAllowlisted true, which puts a lock icon next to your server in the browser, plus sets sv_allowlistInstructions with how to get in. With txAdmin, set Allowlist Mode in Settings, Whitelist instead, since txAdmin manages those two convars. sv_master1 "" makes a server private: the Connect button is disabled, but the server stays in the list, so it cannot hide a server.

Usually no. RCON is an old remote-console protocol that sends traffic in the clear and is a common target for brute-force attacks, so the safest default is to leave rcon_password unset, which disables RCON entirely. This tool omits the line when you leave the field blank. If you truly need remote console access, set a long, random password and never reuse it anywhere else. Write it as set rcon_password "your-password", since current FXServer builds only accept it with set in front.

On FiveM Legacy, start with pure mode 1: it blocks modified game files but still allows audio and known graphics mods. Then add sv_filterRequestControl 1 so players cannot take over vehicles others are in. Entity lockdown and state bag strict mode stop more cheats, but they also break scripts that spawn entities or set state from the client, so turn them on only after testing your resources. Enhanced keeps pure mode on for everyone.

Yes. Without OneSync a server tops out at 32 slots. onesync legacy goes to 64 and onesync on to 2048. Your license key sets a limit too: a free key allows 48 slots, and more needs a Cfx.re Element Club subscription (Argentum 64, Aurum 128, Platinum 2048). This generator warns when your player count is above what your settings allow, so you do not ship slots that players cannot actually join.
