About hashbox.dev

hashbox.dev is a collection of single-purpose developer tools designed to do one thing well.

Every tool runs entirely in your browser. Nothing you type or paste is sent to a server, stored in a database, or shared with third parties. There are no accounts to create, no usage limits, and no premium tiers.

Why this exists

Developers search for utility tools dozens of times a week — cron expression explainers, JSON formatters, Base64 encoders, regex testers. The existing options are typically bloated with ads, littered with cookie consent banners, or bundled into apps that require signups for basic functionality.

hashbox.dev is the alternative: the tool at the top of the page, the answer immediately visible, and nothing else competing for your attention.

How it's built

The site is built with Next.js and deployed on Vercel. Every page is statically generated at build time for fast load times and strong Core Web Vitals scores. The tools themselves are client-side JavaScript — your input never leaves your browser.

Who builds this

hashbox.dev is a project by Aurifex, a technology consultancy based in the UK. If you find a bug, have a tool request, or want to get in touch, email hello@hashbox.dev.
