Fabric 1.21.4 Modpack Server Hosting

42 Fabric 1.21.4 modpacks that MineXHost's QA Lab has tested often enough to report a result. Minecraft 1.21.4 servers run on Java 21; MineXEngine sets it up.

Each QA Lab test is a boot-and-ping test on a MineXHost QA server: MineXEngine installs the modpack, starts the server, and the server must stay running and answer a Minecraft server-list ping (or, if the pack turns that off, accept a connection on its game port). It does not measure sustained TPS, player joins or long-run stability.

A modpack gets a listed page when all of these hold: it is in our QA Lab's test catalogue; it has at least 5 public QA Lab tests with a clear result on MineXEngine 80.0.0 or newer and at least 50% of them passed; no defect in the pack itself is confirmed; a QA Lab test passed in the last 45 days; and its mod loader and Minecraft version are known, from how the pack is published (as resolved when a QA Lab test installed it) or from MineXEngine's detection in a QA Lab test. A loader and Minecraft version page like this one is listed once at least 5 of its packs are. Failures are included in every count; the full results are on the modpack test results page.

All modpack server pages, grouped by mod loader and Minecraft version.

Other Fabric versions

These results come from MineXHost's QA Lab test servers. Test servers differ from customer servers:

  • Test servers may automatically remove a mod that crashes the server.
  • On a customer server, MineXEngine sets aside mods that cannot or should not run there before the first start, such as mods made only for the game client, a second copy of a mod that is installed twice, a mod file too damaged to open, and world-backup mods, because the panel already backs up your server. After a crash it fetches a missing dependency on its own. A mod that crashes the server is named, and you decide whether to remove it.
  • After a crash, a customer server moves a mod aside without asking only in a few narrow cases: a mod whose mods.toml file is broken, a client-only mod that crashes the server, a mod MineXEngine has shown stops the server from starting while it is installed, a second copy of a mod that is installed twice, and the existing copy of a dependency that MineXEngine replaces with the version another mod needs. An empty mod file is removed. Every other mod MineXEngine sets aside is moved into a separate folder, not deleted, and can be put back.
  • Test servers get 12 GB of memory. Plans start at 3 GB, so a large modpack that passes here can run out of memory on a smaller plan.

Pick a plan and a modpack at checkout. MineXEngine installs the pack and sets up the mod loader and Java version.
