About

Website Blueprints is a free toolkit of 58 web tools for designers, developers and small business owners, built by GelFuzion, a web studio that has launched 500+ sites since 2002.

It started as our own bookmarks folder: the QR code site that expires your codes, the DNS checker buried in ads, the password-sharing site that wants an account. We rebuilt them in one place with a few rules: everything is free, nothing needs an account, and tools run in your browser wherever that's technically possible, so your images, passwords and code never leave your device.

Highlights: an ADA compliance checker that scans pages for WCAG 2.1 AA issues and tests whether linked PDFs are tagged, permanent QR codes that never expire, encrypted self-destructing links for sending passwords, SSL, DNS, WHOIS and SPF/DMARC checks, CSS generators, a color palette generator, an image compressor (WebP/AVIF), an email signature generator, and developer utilities like a regex tester, JWT decoder and epoch converter. Each tool has a plain-English guide.
