Keo Optimized (Modrinth) Server Hosting
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. The full method is on the modpack test results page.

| Mod loader | Fabric (detected by MineXEngine) |
| Minecraft version | 26.3 (detected by MineXEngine) |
| Java version | Java 25 (from the Minecraft version) |
| Estimated RAM | 4 GB minimum, 6 GB recommended (Estimated) |
| Smallest plan that fits | Wolf: 6 GB, $30 a month |
Recorded deployment history
Usually works. 139 of 139 recorded deployments booted successfully, across 40 MineXEngine builds. Counting deployments on MineXEngine 80.0.0 or newer only. The most recent recorded deployment was on .
This history covers every deployment MineXEngine recorded for Keo Optimized, not only QA Lab tests. A deployment counts as booted when MineXEngine recorded a clean server start. Installs and boots that failed count against the pack, except failures caused by MineXHost's own infrastructure, which are left out.
How much memory it needs
Estimated: 4 GB minimum and 6 GB recommended. MineXHost estimates this from the pack's mod loader (Fabric), not from a measurement of this pack. More players and added mods need more memory; the RAM calculator helps size a server. The smallest MineXHost plan that covers 6 GB is Wolf (6 GB, $30 a month).
Test servers and customer servers
These results come from deployments MineXEngine recorded on MineXHost servers, including our QA Lab test servers. Test servers differ from customer servers:
- Test servers may automatically remove a mod that crashes the server. Customer servers name the mod and leave the decision to you.
- 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.
Order a server with Keo Optimized already selected. MineXEngine installs the pack and sets up the mod loader and Java version.
