There is no need to hunt for cheats in Cities: Skylines, because the game offers what you want in its own menu. Unlimited money and every building unlocked from the start are built-in options. You do not need to download a program, open a console or type a code. Below we explain where to find them and what each one changes.
Cities: Skylines has no cheat console. Instead, there are built-in options in the game's own Content Manager. They are listed as mods but are not downloaded from anywhere, as they come with the game and turn on with a single click.
The options work across the whole game rather than per city, so they affect every city as soon as you turn them on.
In the console versions, the options are set when you start a city, and it may not be possible to change them later.

Content Manager > Mods
Open the Content Manager from the main menu and switch to the Mods tab. The built-in options are listed there, and all you need to do is turn on the toggle next to them.
Your budget never goes down, and you can build anything you want. It is the game's own built-in option, so no mod download is needed.
Every building, service and landmark becomes available without population requirements.
If you turn off the disasters option when starting your city, earthquakes, tornadoes and similar events never happen.
