Segments JWT Editor & Debugger

Decode, verify & sign JWTs

Free

Native macOS JWT Editor. Decode, sign & verify offline. No data collection. Edit claims visually with date pickers. Fast, private, SwiftUI-built. Segments is a powerful JWT (JSON Web Token) tool built for developers on iPad. Decode, encode, sign, and verify tokens on the go — no server, no internet, no data collection. DECODE INSTANTLY Paste any JWT to instantly see its header, payload, and signature with color-coded syntax highlighting. Purple for header, blue for payload, orange for signature — spot the structure at a glance. SIGN & VERIFY Full support for 9 algorithms: • HMAC — HS256, HS384, HS512 • RSA — RS256, RS384, RS512 • ECDSA — ES256, ES384, ES512 Enter your secret or paste PEM-formatted keys to sign new tokens or verify existing ones. Signature status updates in real-time. EDIT CLAIMS VISUALLY Switch between raw JSON editing and an interactive claims table. Timestamp claims (exp, iat, nbf) get built-in date pickers — no more converting Unix timestamps by hand. SMART HISTORY Every token you work with is saved automatically. With Apple Intelligence enabled, entries get AI-generated names like "Admin User Session" so you can find them later. BUILT FOR iPAD • Multi-window support — open multiple tokens in Split View or Stage Manager • Works in landscape and portrait • Full dark mode support • Localized in English, French, German, and Spanish PRIVACY FIRST All processing happens on-device using Apple's CryptoKit framework. No network requests. No analytics. No data leaves your iPad. Perfect for debugging APIs on the go, reviewing tokens during code review, or verifying JWTs from a mobile client — all without needing your laptop.
