How to install cobblemon
Tutorial to create a cobblemon server
Want to turn your Minecraft server into a Pokemon adventure with Cobblemon, but not sure where to start? This guide covers everything: how to install the mod, which version to choose, which host to use, and how to configure your server so it runs smoothly.
What is Cobblemon?
Cobblemon is a Minecraft mod that brings Pokemon directly into the game with a visual style that stays true to Minecraft (blocks, pixel textures). Unlike Pixelmon, Cobblemon is open-source and runs natively on Fabric and Forge, with generally better multiplayer server performance.
-> Why Cobblemon over Pixelmon?
Cobblemon is lighter, better optimized for servers, and actively developed. It also supports Fabric, making it compatible with a broad library of performance mods like Lithium and Starlight.
-> Cobblemon on the server side
The mod works in a client-server setup: players need the mod installed client-side, and the server must run Fabric or Forge with Cobblemon loaded. Full setup is explained below.
Recommended version in 2026
Cobblemon supports Minecraft 1.21.x with Fabric. Always check compatibility between Cobblemon version, Minecraft version, and Fabric Loader version before you start.
Choosing the right host for Cobblemon
Cobblemon is RAM-heavy: the world constantly spawns Pokemon, which stresses the server much more than vanilla Minecraft. Here is what to check before choosing your host.
Criteria for hosting a Cobblemon server
- •Minimum 4 GB RAM for 1-5 players, 8 GB recommended above that
- •Fabric or Forge support (some hosts only offer vanilla or Spigot)
- •File panel access to upload mods manually
- •Europe location for good ping from France
- •Responsive support if you get stuck during setup
-> How much RAM for Cobblemon?
For a Cobblemon server with 1 to 5 players, plan at least 4 GB. If you add other mods (Sodium, Iris, Create...), jump directly to 6 or 8 GB to avoid freezes and crashes.

Install Cobblemon on your server: step by step
Here is the full process to install Cobblemon on a hosted server. We assume your hosting plan is already active.
1
Create the server with Fabric
In your host panel, create a new server and select Fabric as server type. Choose the Minecraft version compatible with your Cobblemon version (example: 1.21.1). If Fabric is not available directly, choose "Vanilla" first then install Fabric manually through server files.
2
Download Cobblemon
Go to modrinth.com and download the Cobblemon build that matches your Minecraft and Fabric Loader versions. The file is a
.jar.3
Upload the mod to the server
Using your panel file manager, go to your server
/mods/ folder. If the folder does not exist yet, start the server once so it gets created automatically, then stop it. Upload the Cobblemon .jar into this folder.4
Add required dependencies
Cobblemon requires Kotlin for Forge or Fabric Language Kotlin depending on your platform. Download that mod from Modrinth too and place it in
/mods/. Without it, the server will crash on startup.5
Start the server and check logs
Start the server from your panel. Watch the console logs: if Cobblemon loads correctly, you will see a line mentioning
Cobblemon with a version number. Startup crashes often mean a version mismatch between the mod and Fabric.6
Accept the EULA
If this is your first start, the server will stop and ask for Minecraft EULA acceptance. Open
eula.txt in file manager and change eula=false to eula=true, then restart.7
Test in-game connection
Install Cobblemon on the client side (same version as server), launch Minecraft with your Fabric profile, and connect to your server IP. If a Pokemon spawns in front of you, you are good!
Client and server versions must match
If client has Cobblemon 1.5.x while server runs Cobblemon 1.4.x, connection will be rejected. Use exactly the same version on both sides.
Configure Cobblemon on your server
Once the mod is installed, a few settings will improve gameplay quality for your players.
-> Pokemon spawn rates
The `config/cobblemon/main.json` file contains spawn settings. You can adjust Pokemon density per biome there. Default values are balanced, but you can increase them if your RAM allows.
-> Combat difficulty and conditions
Cobblemon includes turn-based battle mechanics. In config files, you can enable or disable PvP battles between players and decide whether wild Pokemon can flee.
-> Datapacks and custom Pokemon
Cobblemon supports Minecraft datapacks. You can add custom Pokemon, tweak existing creature stats, or create biome-specific spawns via a `/datapacks/` folder at server root.
Optimize performance
For a stable Cobblemon server with multiple players, add Lithium (server tick optimization) and Starlight (light engine handling) in your /mods/ folder. These mods are compatible with Cobblemon and significantly reduce CPU load.
Common issues and fixes
-> Server crashes on startup
Check console logs to identify the error. 90% of crashes come from a missing dependency (Fabric Language Kotlin) or a version mismatch between Cobblemon and Fabric Loader. Read the `Caused by:` line carefully.
-> No Pokemon are spawning
Make sure your world is in Survival mode and mob spawning gamerule is enabled (`/gamerule doMobSpawning true`). Pokemon do not spawn in Spectator mode or too close to the initial spawn area.
-> Players cannot connect
Make sure every player uses exactly the same Cobblemon version as the server. Also verify the server port is open in your host panel.
-> Server lags with Cobblemon
If you see lag with 5+ players, increase allocated RAM from your host panel. Move to 6 or 8 GB. You can also lower spawn rates in config files to reduce load.

Frequently asked questions
Is Cobblemon free?
Yes, Cobblemon is a fully free and open-source Minecraft mod. You can download it from Modrinth or CurseForge at no cost. Only multiplayer hosting is paid.
Which Minecraft version is compatible with Cobblemon?
In 2026, Cobblemon supports Minecraft 1.21.x through Fabric. Always check the mod's official Modrinth page for supported versions, because updates are frequent.
Does Cobblemon work on Forge or only Fabric?
Cobblemon is available on Fabric and NeoForge (Forge successor). The Fabric build is usually better supported and more stable for multiplayer servers.
How much RAM do I need for a Cobblemon server?
Minimum 4 GB RAM for 1 to 5 players. For busier servers or additional mods, move to 6 or 8 GB. A server with too little RAM will produce lag and frequent crashes.
Do players need to install Cobblemon client-side?
Yes. Cobblemon is a client-server mod: every player must install the same Cobblemon version (and Fabric Loader) as the server on their own Minecraft. Without client mod installation, server connection is rejected.
Can you play Cobblemon from a vanilla client without client mods?
No. Unlike Bukkit/Spigot plugins, Fabric mods require client-side installation. There is no server-only Cobblemon version that works with a vanilla client.
Which host do you recommend for a Cobblemon server in France?
Minestrator is our main recommendation for Cobblemon servers: France-based servers, intuitive panel, native Fabric support, and strong value for money. Nitrado and Shockbyte are also good alternatives.
Is Cobblemon compatible with other Minecraft mods?
Yes, Cobblemon is compatible with most Fabric mods. It works well with performance mods (Lithium, Starlight), worldgen mods (Terralith, Tectonic), and utility mods (Waystones, Simple Voice Chat). Some mods that modify combat systems or entities can cause conflicts, so always test on a staging server before going live.
