Free Server Saver

Give a memory-constrained server ways to reduce its workload as memory pressure rises.

Free Server Saver responds in stages, from slowing eligible distant mobs and limiting natural spawning to reducing view and simulation distances. You choose which interventions are allowed.

See what is happening

Use /fss status and /fss metrics to check the current state, or inspect recent lag spikes, entities, and chunks with the diagnostic commands. Settings are in serverconfig/freeserversaver-server.toml.

Choose the trade-off

Stronger interventions can change gameplay. The emergency tier can remove eligible distant mobs, and exception quarantine can remove repeatedly failing entities or block entities. Back up your world and review those options before enabling them. Protected mobs include named, tamed, and boss mobs where the relevant safeguards apply.

This release has not yet been validated on a live production server. Test it on a backup before using it on an active server.

This targets memory pressure; it is not a fix for every cause of lag or crashes. Check which modules are active when combining it with other performance or recovery mods.
