About QuickRef.io — Free Developer Tools for Your Browser

QuickRef.io is a free, browser-based toolbox for developers. Every tool runs entirely in your browser — no data is ever sent to a server, no account is required, and the site works offline after the first visit.

Why we built this

Most online developer tools make you sign up, sell your data, or paste sensitive tokens into their servers. We wanted a fast, private alternative. Every tool on QuickRef.io is implemented in pure client-side JavaScript — your JWTs, passwords, Base64 strings, and hashes never leave your machine.

How it works

QuickRef.io is a static site — pure HTML, CSS, and JavaScript. There is no backend, no database, and no server-side processing. Pages are served from a CDN (Cloudflare Pages). This means the site loads fast from anywhere in the world, works offline after first load, and has zero infrastructure to secure or breach.

Cryptographic operations (SHA-256, bcrypt) use the browser's built-in SubtleCrypto API or well-audited open-source libraries (bcryptjs, qrcode.js). No home-grown crypto.

Privacy

We do not use Google Analytics, Meta Pixel, or any behavioural tracking. The only third-party resource loaded is Carbon Ads (a developer-focused ad network used to keep the site free) and Google Fonts. See our Privacy Policy for full details.
