Can a modded Minecraft server start on preview hosting?
Small modpacks with fewer players can use a preview to validate the control panel, settings, logs, and backup workflow. Large modpacks usually need paid persistent hosting.

Pricing path
Preview before paid capacity
Small packs can validate settings, logs, owner handoff, and docs through the preview flow. Heavy packs should move to paid direct-port hosting when the launch needs persistent game access.
Status
Public checks stay visible
The Reactor status page and container health checks keep the preview path measurable while paid hosting demand is validated.
Minecraft modpack hosting FAQ
What makes a Minecraft modpack server expensive?
RAM, CPU spikes during chunk generation, storage for world growth, backup retention, and the number of concurrent players are the biggest cost drivers.
Should I pregenerate chunks for a modpack server?
Pregeneration reduces lag during launch, but it raises setup time, storage use, and backup size. Heavy modpacks should plan for pregeneration before the first public session.
