Full scanner control over USB from the browser, using Chrome's Web Serial API (volume, squelch, hold, scan, avoid, direct entry — everything you'd expect from the physical panel).
Remote sessions: share your scanner with a 6-character code and different access levels, from "listen only" to full control — great if you want someone to follow the scanner without touching anything, or to run it yourself from your phone when you're away. Remote clients can join even from Safari on iPhone or iPad, no install needed.
Live audio and display streamed in real time to anyone who joins the session.
Favorites editor with a System → Department → Channel tree, real-time search, cloud backup, and direct write-back to the scanner's SD card.
Activity log with filters, grouping, and CSV export.
Auto Scan: sweeps a frequency range on its own, stops on active frequencies, and logs every hit.
