How to Host a Free Modded Minecraft Server

Playing Minecraft with mods is great, but playing modded Minecraft with friends over a private server takes it to another level. Setting up a modded server used to require technical knowledge and paid hosting, but in 2026 there are several reliable options that make it genuinely accessible, some entirely free. Here is a practical overview of your real choices.

Option 1: Play Together with Aternos (Free)

Aternos is the most widely used free Minecraft server host. It supports Forge, Fabric, and NeoForge, has a one-click modpack installer for hundreds of popular packs, and handles the server software for you. The main limitation is that your server only runs while you are actively playing — it shuts down after about 10 minutes of inactivity and has a queue system during peak hours. For casual friend groups who schedule their play sessions, it works very well.

To set up a modded Aternos server: create an account, create a new server, select your mod loader (e.g., Fabric 1.21), go to the Modpacks section and search for a pack (or manually add mods under the Mods section), then start the server. Share the server address with your friends and ensure everyone installs the exact same mods on their own Minecraft clients.

Option 2: Self-Host on Your Own PC

If you have a reasonably powerful PC (at least 8 GB RAM, a modern CPU) and a stable internet connection, you can host a server directly from your machine at no cost. Download the server jar for your chosen mod loader (the Fabric server installer and the Forge server installer are both freely available on their respective official sites). Run the jar, accept the EULA, then place the same mods you use on the client side into the server's mods folder. Port-forward port 25565 on your router to allow friends to connect from outside your network.

Self-hosting is free but uses your PC's resources while the server is running. For small friend groups (2–5 people) on lightweight-to-medium modpacks, most modern gaming PCs handle this without issue.

Option 3: Low-Cost Paid Hosting (Best Reliability)

If you want 24/7 uptime without tying up your own PC, affordable hosting starts around $3–6 USD per month from providers like Bisect Hosting, Apex Hosting, or Shockbyte. These services offer one-click installs for virtually every modpack on the CurseForge library, automatic backups, and web-based control panels. For a persistent world that friends can access any time, paid hosting is the practical long-term choice.

Keeping Mods in Sync

The most common problem with modded servers is version mismatches — one player has a different version of a mod than the server. The cleanest solution is to share a CurseForge modpack file (a .zip containing a manifest) that everyone imports through the CurseForge app. This ensures everyone gets the exact same mod files and versions automatically, eliminating manual sync errors.
