Modded Minecraft

Modded Minecraft analytics, mod by mod.

The server-side mod reads TPS and milliseconds per tick against the 50 ms budget, tick time per mod and per dimension, sessions, playtime and store purchases.

Find the mod that eats your tick, the dimension full of chunk loaders and where players spend their time. One server-side mod, no client install.

Questions it answers for Modded Minecraft servers

What the demo dashboard answers for this game.

Which mod is eating my tick?

Tick time split by mod and by dimension, with every spike over 100 ms captured.

Which dimension is heavy?

Loaded chunks, entities and ticking block entities per dimension. Force-loaded counts cover vanilla /forceload only.

Where do players spend their time?

Playtime by dimension, and advancements earned by mod.

Did the pack update help?

Every mod-set change recorded, next to retention for each week of new players.

What sells per player-hour?

Store revenue matched to playtime.

Did the server stay up?

Uptime, restarts and an alert in Discord when it goes down.

What ServerStats tracks on Modded Minecraft servers

One server-side mod for Fabric (with Fabric API) or NeoForge on Minecraft 26.2 and 1.21.1, or Fabric or Forge on 1.20.1. Vanilla and modded clients join without it.

No install yet? Basic mode uses the Server List Ping on port 25565, the same as any Java server. Check any Modded Minecraft server with the Minecraft server status checker.

Plugin-specific payment and gamemode integrations for modded servers are planned. The general dashboard and payments log work today.

The number that matters: MSPT per mod

50ms

The tick budget every mod shares

Target: 20 TPS
Sampler starts: Past 50 ms
Spike recorded: Over 100 ms
Charged to: Mod package or Mixin

A modpack server has the same 50 ms tick as vanilla, but 200 mods share it. MSPT tells you the server is struggling; the per-mod share tells you who is spending the budget.

Fabric, NeoForge and Forge load every mod through one class loader, so ServerStats maps each mod's packages when the server starts and reads the mod id out of Mixin handler names. Code a mod injects into a vanilla class is still charged to that mod, not to Minecraft.

Per-dimension TPS finds the other classic: a dimension full of chunk loaders and machines that drags the whole server while the overworld looks fine.

One mod. About five minutes.

Modded Minecraft questions

Which mod is lagging my modpack server?

ServerStats samples the server thread whenever a tick runs past 50 ms and charges each sample to the innermost mod on the stack. Ticks over 100 ms become lag spikes with the top three mods and the method, and every 5 minutes you get each mod's share of ordinary tick time.

Which loaders and versions are supported?

Fabric (with Fabric API) and NeoForge on Minecraft 26.2 and 1.21.1 (Java 21), and Fabric or Forge (47.1.0 or newer) on 1.20.1 (Java 17), with a jar for each: the file name says the Minecraft version. Forge on other Minecraft versions isn't supported yet.

Do players need the mod in their pack?

No. It's server-side only and registers no blocks, items or packets, so players join as usual.

Can I see what a pack update changed?

Yes. Every change to the mod set is recorded with what was added, removed and updated, so you can compare lag and retention before and after.

Does it send player names?

Not by default on modded servers: privacy.send-player-names is off. Players are UUIDs, hashed when they reach us.

Can I use it with Paper plugins too?

Paper servers use the ServerStats plugin instead. Both report into the same account.

Is it free?

Free covers one server with 24 hours of history, forever, with no card. Operator is $9.99 a month for 10 servers and 90 days of history, which you need for week-on-week trends and D7 or D30 retention. Yearly billing gives two months free.
