Free listings go through the same checkout as paid ones — add to cart, sign in with your Cfx.re account and clear the Tebex checkout at zero. It sounds like a pointless step, but it means the resource lands on your Keymaster account exactly like a paid one, so updates come from the same place and you are not hunting for where you got a file six months ago.
Free does not mean a crippled demo. These are usually smaller resources — one specific mechanic rather than a full system — but installed and configured exactly the same way: folder into resources, ensure resource_name in server.cfg, and the SQL import if there is one.
Support covers free scripts too, though tickets from people who bought something naturally come first. If you find a bug, say so on Discord — fixes reach everyone, because the update comes down through Keymaster.
It is a reasonable way to see how we write before spending anything: download it, read the config, watch resmon 1 with players on your server, and decide for yourself whether you want something bigger from us.
