JWT Lens

JWT Lens is a fast, private JSON Web Token decoder and verifier for developers — a Safari extension that works entirely on your device. Tap the toolbar icon, paste a token (or grab the text you've selected on the page), and instantly see: • Pretty-printed, color-coded Header and Payload • Human-readable timestamps — exp, iat and nbf shown in your local time with relative phrasing ("expires in 59 minutes") • An at-a-glance expiry badge: valid, expired, or not yet valid • Plain-English descriptions of standard claims (iss, sub, aud, and more) Need to check a signature? JWT Lens verifies HS256/384/512, RS256/384/512, PS256/384/512 and ES256/384/512 using a secret or PEM public key you provide — all computed locally with the system's WebCrypto, never sent anywhere. Privacy by design: • No network requests — ever • No analytics, no tracking, no accounts • Nothing is stored: tokens and keys live only in the popup while you use it Whether you're debugging OAuth / OIDC flows, inspecting a bearer token, or learning how JWTs work, JWT Lens keeps it quick, clear, and completely on-device. Universal app: works in Safari on macOS, iOS and iPadOS.
Agent Guild

Agent Guild: Remote brings the AI coding agents running on your computer to your iPhone, your iPad and Apple Vision Pro. See every session at a glance in Cards, or explore them in the Yard, a living 3D campus where each agent works in its own building. Open a session to read its terminal and type into it, with touch keys for arrows, Tab, Esc and Ctrl+C. On iPad and Apple Vision Pro, open several windows side by side. Put the Yard on your TV. Connect your iPhone or iPad to an AirPlay TV or a display, and the Yard fills the screen while you keep working on your device. On Apple Watch, pick a computer, see its sessions at a glance, and tap Listen to hear an agent's latest answer. Agent Guild: Remote connects to a computer running Agent Guild 1.4 or later, over your private tailnet or your own reverse proxy. The TV needs Agent Guild 1.5 or later, and Apple Watch needs 1.7 or later. Scan the sign-in code from Agent Guild's Settings → Remote access, or paste its link. Your computer's address and access token stay in this device's Keychain. No computer yet? Try the demo, with simulated sessions.
