About Json Pod

Json Pod is a free, browser-based suite of developer tools. Every utility runs entirely in your browser — nothing is ever sent to a server.

Why we built it

Developers reach for online tools dozens of times a day — to format JSON, decode a JWT, generate a UUID, test a regex. Most of those tools quietly phone home with your data. We think that is wrong. Json Pod was built on a simple principle: developer tools should be fast, free, and private. Your data is yours. It never leaves your browser.

Available tools

→JSON Formatter & Validator — Format, validate, and explore JSON with syntax highlighting and error reporting.
→JSON Diff — Compare two JSON documents side-by-side and highlight the differences.
→JSON Minifier — Strip whitespace from JSON to minimise payload size.
→Regex Tester — Write and test regular expressions with live match highlighting.
→JWT Decoder — Decode and inspect JSON Web Tokens — header, payload, and signature.
→UUID Generator — Generate v4 UUIDs instantly, in bulk.
→Hash Generator — Compute MD5, SHA-1, SHA-256, and SHA-512 hashes client-side.
→Base64 Encode / Decode — Encode text or binary data to Base64 and decode it back.
→Unix Timestamp — Convert between human-readable dates and Unix timestamps.
→Cron Builder — Build and understand cron expressions with a visual editor.

Privacy commitment

Every tool on Json Pod runs 100% client-side. No input you type or paste is transmitted anywhere. We do not require accounts, we do not set first-party cookies, and we do not run analytics that track your behaviour. The only third-party requests your browser makes are to load Google Fonts and, optionally, Google AdSense ads that help keep the site free.

Built with

Json Pod is built with React 19, TanStack Start (SSR + file-based routing), and Tailwind CSS. All cryptographic operations use the native Web Crypto API — no third-party crypto libraries are shipped to the browser.
