About f1macu

Small, free tools for the games you play.

What this site is

f1macu is a small collection of companion tools for games that have a lot of maths under the hood: build planners, damage and DPS calculators, item databases and stat checkers. Each game gets its own page, built around the questions players actually ask, such as "how does armor work?" or "which setup does the most damage?".

The tools run in your browser. You do not need an account, and your saved builds stay on your own device.

Who makes it

I'm Max, a developer based in Brisbane, Australia, with a background in Computer Science. I build these tools on my own because I like turning simple ideas into practical projects that save people a bit of time. f1macu is an independent project and is not run by, or connected to, any game studio or publisher.

The tools

  • Spudlab: a Brotato build planner with weapon DPS from your own stats, a weapon, item and character database, and armor, dodge and harvesting calculators.
  • Coreplan: a Core Keeper build planner covering armor, rings, necklaces, weapons, talent points and set bonuses.

Where the numbers come from

Game data comes from community wikis, mainly the Brotato Wiki and the Core Keeper Wiki, which are published under Creative Commons licences (CC BY-SA). The formulas, calculators and interfaces are written by me. No game art, music or other copyrighted game assets are used.

I do my best to keep the numbers right, but games get patched and I am a one-person project, so a value can occasionally be out of date or wrong. If you spot one, please tell me at [email protected] and I will fix it.

How it is funded

The tools are free to use. The site is supported by advertising (Google AdSense) and by voluntary donations through Buy Me a Coffee. Ads never change the numbers a tool shows. See the Privacy Policy for how advertising works and how to control it.

Not affiliated

f1macu is unofficial fan-made work. It is not affiliated with or endorsed by any game developer or publisher. All game names and trademarks belong to their owners.
