About Million Forge
A catalog of 166+ instant calculators, games, and utilities. All run locally in your browser. Nothing leaves your device.
Practical tools for the numbers people actually need: mortgage payments, paint quantities, safe withdrawal rates, compound growth, body composition, unit conversions, and classic games that work offline. The design goal is McMaster-Carr speed and clarity—find it, use it, close the tab.
- Every calculation runs in your browser with JavaScript. No server round-trips for results.
- Inputs and results stay on your device. We do not store, log, or transmit your data.
- Tools load instantly because the site is a static export served from a CDN.
- Local storage is used only for recents, favorites, and game scores on this device.
Most online calculators are slow, bloated with ads, or require sign-up. We wanted the opposite: one focused place for high-signal tools that respect your time and privacy. New tools are added only when they solve a real, recurring problem with clean math or logic.
The site is free. We show a small number of ads via Google AdSense on many pages and include occasional affiliate links (disclosed). This helps cover hosting and development. You can use every tool without engaging ads or links.
Every tool must be immediately useful with good defaults, produce correct results, and stay fast. No placeholders, no "coming soon", no demo modes. If a page exists, it works.
