What ships in the box

Everything below is inside the jar — one download.

The /meow suite

Twelve commands — health, tps, profiler, activity, report and seven more — under one root.

First-run experience

First-boot setup, an intro cinematic, setup presets, and a /meow perfhud overlay.

Reports, one artifact

One command produces one JSON artifact, viewable at a short URL on this domain.

Health, one command

/meow health answers TPS, MSPT, memory, chunks, entities and platform on one page — green inside the tick budget, red out of it.

Example /meow health output.

Reports that end up here

/meow report writes one artifact and prints where it went. An uploaded report renders at meowmc.org/r/<id> and is kept 30 days before it expires.

Anyone with the report URL can read it.

Example /meow report output.

server console
[12:04:11] [Server thread/INFO]: /meow report[12:04:14] [Server thread/INFO]: report written to reports/meowmc-report-20261016-120411.json

Straight answers

  • Every number carries its method.

    The hardware, the load, the setup. No benchmark headline without its recipe.

  • Paper-lineage plugins keep working.

    Existing plugins behave as they do on Paper; the module system is a separate surface that arrives with the launcher.

  • Two tick modes, one stated tradeoff.

    Single-thread is the default; regionized multithreading is opt-in with its compatibility contract documented.
