Who we are and what we do
๐ฏWhat Suzf Is
Suzf is a growing collection of small, fast, privacy-first web tools for developers, writers, and anyone who just needs to get a quick task done. Every tool works the moment the page loads โ no sign-up, no install, no upload. Open it, use it, close it.
๐Privacy by Design
Almost everything runs entirely in your browser. When you format JSON, generate a password, or count words, the data never leaves your device โ there is no server to send it to. The one exception is the SSL checker, which must open a connection from a server; even then, we do not store the domains you look up. See our Privacy Policy for the full details.
๐งโ๐ปWho It's For
Developers reaching for a quick encode, decode, or converter between other tasks; writers and students checking length and formatting; and anyone who would rather not paste sensitive text into an unknown website. If a tool saves you a search, it belongs here.
๐ The Tools
JSON Formatter, Base64 Encoder/Decoder, URL Codec, Timestamp Converter, Password Generator, UUID Generator, Regex Tester, Cron Generator, SSL Checker, Word Counter, BMI Calculator, and a browser-based WebSocket Tester โ with more added over time.
โกHow It's Built
Suzf is built with Next.js, TypeScript, and Tailwind CSS, served as static pages for speed, and available in English and Chinese. Pages are designed to be fast, accessible, and to work well on phones and desktops alike.
๐Writing & Guides
Beyond the tools, our blog shares practical, hands-on notes on DevOps and infrastructure โ Docker, Terraform, Consul, Nomad and more โ written from real-world use.
๐ฌFeedback & Contact
Suzf is actively maintained and shaped by the people who use it. If a tool is missing, broken, or could be better, tell us on the Contact page โ we read every message.
