JS Shell

JS Shell is a portable terminal you can carry in your pocket. It bundles a real Unix-like shell with a QuickJS-powered JavaScript REPL, a local HTTP server, and a persistent SQLite-backed key-value store — all running entirely on your device, with no cloud services and no account required. KEY FEATURES - Shell commands — ls, cat, rm, edit, run, paste, fetch, curl, extract, kv - fetch — download a tarball or zip and unpack it under a sandboxed directory in one step. Cached after first run; say "update" to re-download. - extract — handles .tar / .tar.gz / .tgz / .gz / .zip with full path safety - curl — full HTTP request tool: -X -H -d -i -I -o -A -m -v all supported - Local HTTP server — preview your HTML / CSS / JS instantly via http://localhost - Embedded WebView — open pages in-app with a single tap JAVASCRIPT REPL - Real QuickJS engine running on device - CommonJS modules: write `module.exports = {...}` and `require('./mod.js')` - fetch, setTimeout, setInterval all work - :q to exit back to shell PERSISTENT KEY-VALUE STORE - Real SQLite B-tree on disk — O(log n) lookups, not "scan a JSON file" - Same-origin REST API exposed at /_kv from your local pages - PUT / GET / DELETE / LIST — works from JS fetch() in the WebView VOICE INPUT - Speak commands in 40+ languages — Mandarin, Japanese, Korean, Spanish, French, German, Russian, Arabic, Hindi, Vietnamese and more all auto-translate to shell commands - Continuous listening with smart silence detection QR CODE SCRIPTS - Scan a QR code to install a script — scripts are sandboxed by origin so a QR from one publisher cannot overwrite files from another - Custom jsshell:// deep-link scheme for one-tap installs - Built-in QR scanner with camera support PRIVACY - 100% local. No analytics. No ads. No tracking. No account. - Your files live in the app's private storage and never leave your device. - Network requests only happen when you explicitly run fetch / curl / open. UI LANGUAGE JS Shell automatically picks the UI language from your system settings: English, 中文, 日本語, 한국어, Español, Français, Deutsch, Português, Русский. PERMISSIONS WE USE - Internet — only for fetch / curl URLs you provide - Camera — only when you open the QR scanner - Microphone — only when you tap the voice input button - No location, no contacts, no storage outside the app sandbox GREAT FOR - Developers who want a pocket terminal for quick experiments - JavaScript learners who want a fast REPL anywhere - Power users running self-hosted scripts via QR distribution - Web devs prototyping without setting up a laptop Open source spirit, built with Flutter. Works offline, respects your data.
