Install a modpack

Browse Modrinth, CurseForge, FTB and ATLauncher, or import a packwiz manifest or server-pack archive. CoalHost sets the right loader automatically whenever the provider exposes a server-ready build.

During registration

The fastest path: pick a modpack while creating your account.

  1. Open the register page.
  2. In the "What should we preinstall?" field, search by name (e.g. All the Mods 9).
  3. Click your modpack — server software and version lock automatically.
  4. Continue to checkout. The modpack installs after your first payment.

On an existing server

  1. Open the server in the dashboard.
  2. Go to Modpacks tab.
  3. Search and install. Existing world data stays intact unless you opt to wipe it.

Import from other launchers or custom packs

  1. Paste a direct .mrpack, .zip or public pack.toml URL into the import form.
  2. Or upload a local .mrpack / .zip file from your computer.
  3. CoalHost resolves the archive or packwiz manifest, creates a backup, then installs the matching loader and files.

Heads up: Big modpacks (300+ mods) need 6–8 GB RAM minimum. Upgrade your plan first via the billing portal if your current RAM is too low — otherwise the server may crash on startup.

Switch modpacks later

You can install a different modpack any time. Use Modpacks → Switch on the server page — back up your world first if you want to keep it.
