Choose Your Plan

Plan	Best For	Player Capacity
Starter	Small vanilla servers, friends & family	~5-8 players
Pro	Paper/Purpur servers with light modpacks	~10-20 players
Premium	Heavy modpacks, large communities, MySQL access	~25-35 players

Tip

Not sure which to pick? Start with Starter or Pro — you can upgrade instantly from the panel if you need more resources.

Quick Start

1. Create your server

   Go to panel.mambahost.com → Create Server → Minecraft Java

2. Choose your server type

   Select Vanilla, Paper, Purpur, Forge, or Fabric based on your needs

3. Select your version and deploy

   Pick your Minecraft version, choose a plan, and click Deploy

4. Wait for setup

   Your server will be ready in under 2 minutes with a default world

5. Connect and play

   Find your server IP in the panel and connect from your Minecraft client

Note

Migrating an existing server? Upload your world files via SFTP before starting the server to avoid generating a new world.

Server Types Explained

Type	Use Case	Plugin/Mod Support
Vanilla	Pure Minecraft experience	None
Paper / Purpur	Performance + plugins	Bukkit/Spigot plugins
Forge	Mods (client + server)	Forge mods
Fabric	Lightweight mods	Fabric mods

Caution

Forge and Fabric are not compatible. Players must use the same mod loader and mods as your server.

---

Upload Your World

1. Stop the server from the panel

2. Connect via SFTP (port 2022) using credentials from the panel

3. Upload your world folders (world, world_nether, world_the_end) to /home/container

4. Update server.properties — set level-name to match your world folder name

5. Start the server and verify your world loads correctly

Tip

For files over 100 MB, always use SFTP instead of the web file manager for faster, more reliable uploads.

---

Install Plugins (Paper/Purpur)

1. Download plugins from SpigotMC, Modrinth, or Hangar

2. Upload .jar files to the /plugins folder via SFTP or file manager

3. Restart the server to load the plugins

4. Configure plugins — edit the config files generated in /plugins/<plugin-name>/

Caution

Check compatibility! Make sure plugins support your Minecraft version. Incompatible plugins can crash your server.

---

Install Mods (Forge/Fabric)

1. Download mods from CurseForge or Modrinth

2. Upload mods to the /mods folder

3. Upload config files to /config if the modpack includes them

4. Verify the server jar matches your mod loader version

5. Restart the server and check the console for errors

Version Mismatch

Your Forge/Fabric loader version must match your Minecraft version exactly. A Forge 1.20.1 loader won’t work with Minecraft 1.20.4.

Performance Optimization

Recommended Settings

Setting	Recommended Value	Location
View Distance	8-10	server.properties
Simulation Distance	6-8	server.properties
Max Players	Based on your plan	server.properties

Paper/Purpur Optimizations

Tip

Paper and Purpur include built-in optimizations. Edit paper-global.yml and paper-world-defaults.yml for advanced tuning.

Key optimizations:

• Enable async chunk loading
• Reduce entity activation ranges
• Optimize redstone and hopper mechanics

When to Upgrade

Consider upgrading your plan when:

• RAM usage consistently exceeds 80%
• TPS (ticks per second) drops below 19
• Players experience noticeable lag

---

Backups

Note

All plans include automatic backups. Configure backup schedules in Panel → Schedules.

Best practices:

• Schedule daily backups during low-activity hours
• Create manual backups before installing new plugins or mods
• Download critical backups to your local machine periodically

---

Common Issues

Problem	Solution
Server won’t start	Check console for errors — usually a plugin/mod conflict or wrong Java version
Players can’t connect	Verify server is running, check IP/port, ensure versions match
Lag spikes	Reduce view distance, remove heavy plugins, check for redstone/hopper farms
Mods not loading	Verify mod versions match your Minecraft and loader version
Out of memory	Upgrade your plan or reduce loaded chunks/entities
