Download a free website for your city. For anyone who wants it, here it is. I recommend registering a .city domain, which is very cheap and matches FiveM cities better. Buy some cheap hosting and upload everything to your server.
The site is here and ready. You just need to add your city’s logo, write a nice description optimized for SEO, implement your favorite FiveM shop system in your city, like Hydrus, and that’s it.
Your city will be 100% connected.
