Connect Buddy to your paired Mac Mini (or another machine) and keep track of active work, approvals, managed sessions, and follow-up tasks without sitting at your desk. With Buddy, you can: - review what your agents are doing - continue observed work from your phone - start and monitor managed sessions - handle approval and review flows - check recent work, outputs, and session history - stay in sync with your local agent runtime Buddy is built for developers who use local and desktop-based coding agents and want lightweight control while away from the keyboard. Current highlights: - mobile view of agent activity and status - managed and observed session workflows - approval handling from your phone - recurring managed tasks - prompt attachments and voice dictation - local-first workflow with your paired machine Buddy works together with the Asynq agent daemon (asynq-agentd) running on your computer.

JWT Lens is a fast, private JSON Web Token decoder and verifier for developers โ 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: โข Pretty-printed, color-coded Header and Payload โข Human-readable timestamps โ exp, iat and nbf shown in your local time with relative phrasing ("expires in 59 minutes") โข An at-a-glance expiry badge: valid, expired, or not yet valid โข 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 โ all computed locally with the system's WebCrypto, never sent anywhere. Privacy by design: โข No network requests โ ever โข No analytics, no tracking, no accounts โข 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.
