About uPinned
Free developer tools that respect your privacy. No accounts, no tracking, no servers processing your data.
Our Mission
uPinned was born out of a simple frustration: too many online developer tools require you to send your data to a remote server just to format JSON, decode a token, or generate a UUID. Some require accounts. Some inject ads into your output. Some quietly log everything you paste.
We believe developer tools should be free, fast, and private. That is why every tool on uPinned runs entirely in your browser. Your data never leaves your machine. There is no backend server processing your inputs, no database storing your queries, and no analytics tracking what you paste.
Our goal is to build the most useful, trustworthy, and developer-friendly tool suite on the web — and to keep it free for everyone.
Our Values
Privacy First
Every tool processes data exclusively in your browser using JavaScript. We have no backend, no database, and no way to see what you paste. Your API keys, tokens, and sensitive data are yours alone.
Speed & Simplicity
No bloated frameworks. No unnecessary dependencies. Every page is statically generated at build time, ensuring the fastest possible load times. Open a tool and it just works.
Zero Barriers
No accounts, no sign-ups, no rate limits, no paywalls. Every tool is completely free with no hidden limitations. We believe good tools should be accessible to everyone.
Built for Developers
Every tool is designed with real developer workflows in mind. Keyboard shortcuts, clean interfaces, sensible defaults, and instant results. We use these tools daily and build what we need.

How We Handle Your Data
We do not collect, store, or transmit any user input data. Every tool runs 100% in your browser. When you paste text into a tool, it is processed by JavaScript running on your device. Nothing is sent to our servers or any third party.
We use Vercel for hosting, which may collect standard server logs (IP address, page visited, timestamp) for operational purposes. We use Google AdSense for advertising, which uses cookies to serve relevant ads. See our Privacy Policy for full details.
You can verify our privacy claims by opening your browser's developer tools (Network tab) while using any tool — you will see zero outgoing requests with your data.
