title: Plugins, mods, and server software
description: Choose between Paper, Fabric, Forge, NeoForge, and Vanilla before installing extensions.

Plugins and mods are different file types. Choose the server software first, then install projects made for that software and Minecraft version.

| Software | Use it for | Install location | Players need files? |
| --- | --- | --- | --- |
| Paper, Purpur, or Leaf | Bukkit/Paper plugins | `plugins` | Usually no |
| Fabric | Fabric mods and modpacks | `mods` | Often yes |
| Forge | Forge mods and modpacks | `mods` | Often yes |
| NeoForge | NeoForge mods and modpacks | `mods` | Often yes |
| Vanilla | Unmodified Minecraft | None | No |

## Choose Paper for plugins

Paper is the simplest choice for most public or SMP servers. Plugins can add homes, permissions, claims, minigames, and other server-side features without requiring every player to install them.

Use the panel's **Plugins** page to search Modrinth and install compatible projects. See [Install a plugin](/guides/installing-plugins).

## Choose a mod loader for mods

Fabric, Forge, and NeoForge load mods from the `mods` folder. The panel labels the installer page **Mods** for these servers.

Many mods must also be installed on every player's computer. Everyone should use the same Minecraft version, mod loader, and mod versions. A modpack is the easiest way to keep that setup consistent.

## Check compatibility before installing

On the project's Modrinth page, check:

- The supported Minecraft version.
- The supported loader or platform.
- Whether it is required on the client, server, or both.
- Any required dependencies.

Do not rename a mod to make it look like a plugin, or place the same JAR in both folders. It will not convert between formats.

## If the server will not start

Open **Console** and find the first error naming a mod, plugin, dependency, loader, or Minecraft version.

Remove the incompatible JAR, start the server again, and download the correct release. Do not delete the full `plugins` or `mods` folder unless you intend to remove everything and already have a backup.

## Switching later

Changing between Paper and a mod loader is a software change, not a normal update. Back up the server first and read [Change the version or server software](/guides/changing-software-version).
