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.

kube-coder mobile is the companion app for kube-coder, an open-source, self-hosted cloud development platform (github.com/imran31415/kube-coder). If you run a kube-coder workspace, this app lets you drive it from anywhere. CONNECT IN SECONDS Point the app at your workspace host and paste the API token from your dashboard (Settings โ Mobile app). No account, no sign-up โ the app talks directly to your own server, and the token is stored securely on your device. Just looking? Tap "Explore the public demo" on the first screen to browse a read-only demo workspace โ no token needed. WHAT YOU CAN DO โข Tasks โ start a coding task for your AI assistant, follow the live session, and send follow-ups when it needs input. Active work up front; finished tasks tucked under Done. โข Live terminal โ the task view renders your workspace's real terminal, the same session the web dashboard shows. โข Apps โ see the dev servers running in your workspace and open them in-app. Split the screen to watch your app change while the assistant works on it. โข Desktop โ your one-tap launchers (build prompts, URLs, shell commands), shared with the web dashboard. โข Memory โ browse what your workspace remembers. โข Metrics โ live CPU, memory, and disk, plus service health. PRIVATE BY DESIGN No accounts. No analytics. No third-party services. The app connects only to the workspace host you configure, over HTTPS, using your token. kube-coder itself is open source โ read the code, run your own, or try the demo: github.com/imran31415/kube-coder
