JWT Lens vs PromptPager

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.

PromptPager keeps you connected to coding agents and terminal sessions running on your Mac. See active Claude Code, Codex, opencode, and terminal sessions from your iPhone or iPad. When an agent needs a decision, PromptPager sends a notification to your iPhone and Apple Watch so you can approve, deny, choose an option, or send a response without returning to your desk. FEATURES • Monitor active coding-agent and terminal sessions • Read live session output from iPhone and iPad • Receive actionable notifications on iPhone and Apple Watch • Respond directly from your wrist • Discover your PromptPager bridge automatically on the local network • Pair securely with a one-time code • Use your own authenticated HTTPS push relay for closed-app delivery • No PromptPager account or subscription required HOW IT WORKS Run the open-source PromptPager bridge on your Mac, pair the app using the six-digit code shown by the bridge, and keep working with your preferred coding agent. PromptPager connects directly to infrastructure you control. The companion bridge supports Claude Code, Codex, opencode, and terminal/tmux sessions. Setup documentation and source code are available from the project website. PromptPager is an independent developer utility and is not affiliated with Anthropic, OpenAI, or SST/opencode.
