Circinus

A precision instrument for modded RimWorld.

Find out what your mods actually cost, measured against machines like yours. Not a leaderboard. Cost is not the same thing as quality.

Three questions, honestly answered

Milliseconds are never compared across different computers. Only share of frame time travels, because it divides out the hardware.

Question one

Will this list run on my machine?

Expected TPS and FPS drawn from installs in the same measured hardware class as yours.

 Question two

Is it the mod, or is it me?

Your run against the median run with a similar list on similar hardware.

 Question three

What is costing me frames?

Cost per mod and per Harmony patch, with the interval and the sample count beside every figure.

What this will not tell you

A tool that answers everything confidently is a tool that is sometimes confidently wrong. These are refusals by design, not gaps waiting to be filled.

It will not rank thin dataBelow a minimum number of runs a mod shows insufficient data rather than a position in a table.
It will not blame for induced costIf one mod makes another's work larger, the time lands on the second. Untangling that needs a controlled test on one machine.
It will not compare across hardwareAbsolute milliseconds from different computers are never averaged together.
It will not call a mod badA framework many mods depend on costs more than a mod adding one hat. That is arithmetic, not a verdict.

Open by default

A versioned REST API serves the same data the site does, using the same types the in-game mod writes. Submission is opt-in, off by default, and scrubbed of file paths before it ever leaves your machine.
