What it is

The Toolshed is a free collection of everyday utility tools — mortgage and loan calculators, unit converters, a QR code generator, a password generator, and more. Everything runs in your browser. There's nothing to install, no account to create, and nothing personal is tracked.

Why it exists

The small calculations that come up in ordinary weeks — what will this mortgage actually cost, how do I split this bill, what's the BMI for these numbers, how do I convert this date format — tend to scatter across a dozen different sites full of ads, dark patterns, and email capture forms. The Toolshed puts them in one plain place that gets out of your way.

How it's built

The site is plain HTML, CSS, and JavaScript — no frameworks, no build step, no databases. Each tool page is a self-contained file. Hosting is on Netlify. The page-view counter is a tiny serverless function that increments a counter in Netlify Blobs; it records nothing beyond the count itself.

The currency converter pulls live exchange rates from the European Central Bank's public API. The QR code generator uses the open-source qrcode.js library. Every other calculation is done with vanilla JavaScript with no external dependencies.
