How to set up your Cave Horror Project 1 server

Create your account, top up your balance and create a Large server.
Create the world with Forge as the loader and Minecraft 1.20.1 as the version.
In "Mods", add Cave Horror Project 1's mods from the Modrinth catalog (the list is in the dependencies tab of its Modrinth page). The catalog only shows what works with your world, and the panel installs the right version of each mod along with its libraries.
Start the server. The first boot takes a bit longer because it downloads and installs the mods.
Your friends download the .mrpack modpack from the panel in one click and import it in the Modrinth App or Prism Launcher.
Share the server address and you're in: they join through Multiplayer.

Frequently asked questions

Which Minecraft version does Cave Horror Project 1 need?

Cave Horror Project 1 has versions for Forge: 1.20.1. The newest is "Cave Horror Project 1 v3.6.1" (October 1, 2026). Create your world with Forge and Minecraft 1.20.1: that's the combo its latest release is built for.

Can I change the server's Minecraft version later?

Yes, upward: when Cave Horror Project 1 ships a newer version, you update and the panel backs up your world first. Going back down isn't possible, because Minecraft can't open worlds saved on a newer version; to play an older one, create another world.

How much RAM does a Cave Horror Project 1 server need?

We recommend a Large server with 16 GB. Its latest version ships at least 191 mods from Modrinth. If lots of people play at once or you explore a ton, size up from the panel without losing your world.

Do my friends have to install Cave Horror Project 1 to join?

Yes: every player needs Cave Horror Project 1 in their Minecraft, on the same versions as the server. The easiest way is to import the modpack in the Modrinth App or Prism Launcher. If you build the server from the panel's catalog, the .mrpack they download has exactly the same mods.

How much does a Cave Horror Project 1 server cost?

With a Large server and 10 hours of play a week, about $345.13 MXN a month, storage included. With 5 hours, about $203.64 MXN. You only pay while the server is on; if nobody's playing, it shuts itself off.

Can I play Cave Horror Project 1 on an offline-mode (non-premium) server?

Yes. Offline mode is a server setting, not a modpack one: you turn it on in the panel's "Access" tab. Use it with the whitelist on and no operators, because in that mode the server doesn't verify who each player is.
