Web & Mobile (Serve / PWA)

Halny includes a built-in HTTPS server — the same UI in a browser, plus an installable PWA for phones.

Enabling

  • Desktop: Settings → Serwer — set login & password and press Start; LAN URLs are shown for convenience
  • Server/CLI: --headless --serve --port=8443 --user=<name> --password=<secret> (see Headless Server)

Browser client

  • Log in at https://<host>:8443 — the login page is localized (EN/PL/FR/ES/DE/IT) and follows your browser language
  • Everything works in the browser: sessions, chat, preview/editing, remote SSH, statistics, settings (the server tab itself is hidden)
  • Native file dialogs are replaced by an in-app folder picker; files can be downloaded

PWA on your phone

  1. Open the URL in your mobile browser and log in
  2. Use Add to Home Screen — the app installs as a standalone PWA with offline shell caching

The mobile layout adapts: hamburger menu, swipeable sidebar and dock, long-press context menus, safe-area padding. Floating action buttons (new chat, file actions) hide themselves when they would overlap the open drawer, the “New project…” pill replaces the desktop toolbar button, and theme/logout live at the bottom of the sidebar's Settings section — no duplicated top-bar controls.

Security

  • Login & password (scrypt-hashed), rate-limited per IP
  • Session cookie httpOnly/Secure/SameSite=Lax, 30-day sliding expiry; WebSocket rejects unauthenticated connections before handshake
  • Self-signed TLS by default — bring your own certificate with --cert/--key for a clean padlock
  • Intended for LAN/VPN use; do not expose to the public internet with only built-in auth
