Our Mission
CodePersia was built out of frustration with the state of online developer tools. Too many require signups, collect data unnecessarily, send your input to remote servers, or bury useful functionality behind paywalls. We wanted something better: a collection of fast, free, and private tools that respect the developer workflow.
Our goal is simple — provide the most commonly needed developer utilities in one place, with zero friction. No accounts, no rate limits, no data collection. You paste your input, get your output, and move on with your day. Every tool is designed to load instantly, work offline once cached, and handle large inputs without breaking a sweat.
How It Works
Every tool on CodePersia processes data entirely in your browser using client-side JavaScript. When you format JSON, encode a Base64 string, or generate UUIDs, the computation happens on your machine — nothing is sent to our servers or any third party. You can verify this yourself by opening your browser's Network tab while using any tool.
This architecture means your sensitive data — API keys, tokens, configuration files, proprietary payloads — never leaves your device. It also means the tools work without an internet connection once the page has loaded, and there are no usage limits since there is no server to overload.
The Tech Stack
CodePersia is built with Next.js, TypeScript, and Tailwind CSS. The site is hosted on Vercel for fast global edge delivery. Cryptographic operations use the Web Crypto API for secure random generation, and text encoding relies on the browser-native TextEncoder and TextDecoder APIs for full Unicode support.
