Direct answer
Choose based on what the server must run. Vanilla is the simplest official server. Paper is the usual choice for Bukkit/Paper plugins. Fabric is a lightweight mod loader with its own mod ecosystem. NeoForge and Forge are commonly used by modpacks that require them. Folia is a specialized Paper-family server with different threading behavior and stricter plugin compatibility requirements.
Quick comparison
| Software | Best fit | Plugins / mods | Main caution |
|---|---|---|---|
| Vanilla | Official behavior and simple private servers | No Bukkit/Paper plugins | Fewer administration and optimization features |
| Paper | Plugin-based SMPs and general servers | Bukkit/Spigot/Paper plugins | Not perfectly identical to Vanilla mechanics |
| Fabric | Lightweight modded servers | Fabric mods | Clients may need matching mods |
| NeoForge / Forge | Modpacks and larger mod ecosystems | Loader-specific mods | Use the loader and version the pack requires |
| Folia | Advanced regionized multithreaded workloads | Only compatible plugins | Do not assume a Paper plugin is Folia-safe |
When Paper makes sense
Paper is useful when you want plugins for permissions, moderation, protection, backups, maps, economy, or other server-side features. It is designed around the Bukkit/Paper plugin ecosystem and provides extensive configuration and diagnostics.
Paper can differ from Vanilla in edge cases. Technical redstone or farm behavior can be affected by server implementations and configuration, so a technical Vanilla-focused community should test its important mechanics before migrating.
When you need a mod loader
If the content you want is distributed as Fabric, NeoForge, or Forge mods, run the corresponding loader. A modpack normally tells you exactly which loader and Minecraft version it expects. Do not install a Fabric or Forge mod in Paper's plugins folder.
Can you switch later?
Usually, but treat every migration as a maintenance event. Back up the world, configuration, and plugins/mods first. Paper currently handles Vanilla-to-Paper world conversion automatically, but moving between plugin and mod ecosystems can leave features unavailable. Worlds that contain blocks or data from mods may not be safely usable on software that does not know those mods.
A simple beginner rule
If you only want a private unmodified server, Vanilla is enough. If you specifically want server plugins, start with Paper. If you are installing a modpack, use the loader required by that modpack instead of choosing Paper because a tutorial called it “optimized.”
- If you need ordinary Paper plugins and traditional tick behavior, start by evaluating Paper or an API-compatible fork. If you need Fabric/NeoForge mods, choose the loader required by your modpack.
- Folia is a region-threaded architecture: do not select it merely because your CPU has many cores; verify every required plugin supports its scheduler/threading model.
- Velocity is a proxy for a multi-server network, not a replacement for the backend world server. Prototype the chosen stack with your real plugins before migrating player data.
