Since there are many Discord shops charging a lot for this, I’ll leave here a free website for you to obfuscate your framework, your scripts, your maps, and everything you consider necessary on FiveM.
Why is it necessary to obfuscate on FiveM?

It’s advisable to always obfuscate before sending your precious files to the VPS. Data leaks are everywhere and dumps are on the rise and getting more and more powerful. I wouldn’t be surprised if one day they also manage to get the “server” folder one way or another.
I also recommend obfuscating that framework you bought open source. If you don’t want to obfuscate everything, at least do it for the vrp folder. It’s the most important one. Developers such as “Hensa Rewritten” ask their clients to obfuscate their open files using FiveM’s own keymaster, under penalty of a fine, for example.
I obfuscated my script, now what?
Always keep a backup of your open files in a safe place, such as Google Drive (set it to private and with a password for your security), because you never know when FiveM will stop supporting something, as was the case with luraph and its famous error screen:

Note: Even with your files obfuscated, you are still not 100% protected from someone with knowledge in deobfuscation. For better protection, look for a file authentication system via IP, token, etc.
