About

7DTD Tool Studio is a fan-made collection of calculators and tools for 7 Days to Die. We are not affiliated with The Fun Pimps or Behaviour Interactive.

Why We Built This

Every 7DTD player has been there: standing in front of a workbench, wondering what materials are needed to craft something. Or staring at the blood moon sky, wondering if the base will hold. Existing tools rely on manual formulas that go out of date. We wanted something better.

How It Works

All numbers come directly from the game's XML files — items.xml, recipes.xml, blocks.xml, gamestages.xml, entitygroups.xml, and progression.xml. A build-time script parses these files into JSON, and all calculations run in your browser. No manual data entry. No outdated formulas.

Tech Stack

Next.js 15 + TypeScript + Tailwind CSS · Recharts for data visualization · Web Workers for heavy computation · Deployed on Vercel · All data is static JSON — no backend, no database, no accounts.
