Terminal Sync
A persistent, synchronized terminal across every device. Open one shell — or many — on the host, drive them from your phone or laptop, and never lose a session again, even if the link drops — anywhere in the world.
Persistent host shell
A canonical shell runs on the host machine and keeps running even when the connection between the two machines drops. Close your laptop, switch devices, or lose Wi‑Fi — your builds, deploys and long jobs never stop. Reconnect and you resume the exact same session with full scrollback intact; nothing is lost.
Many sessions, side by side
Open multiple concurrent terminal sessions on a device and switch between them like tabs or pages. Run a build in one, tail logs in another, keep an SSH box in a third — each is independently persistent and reattachable.
Attach from anything
Mac, Windows, Linux, iPhone, iPad, Android, or any browser. Each client renders the terminal locally and syncs I/O — not pixels — so it feels like you're sitting at the host, worldwide, at near‑zero latency.
Copy, cut & paste everywhere
Full clipboard bridging across every platform — copy on your phone, paste into the host shell; select host output and copy it locally. Works in the native apps, the CLI and Flutter.
Offline‑resilient
Type while the link is down and your input is buffered locally, then replayed on reconnect. The remote machine keeps your output safe and the session restores its scrollback on attach.
Session Monitor built in
Session Monitor watches every session continuously — even when no one is attached. Get notified the moment a run finishes, stalls or pauses (no output for a configurable idle window, with escalation warnings), or the shell stops — even if you were disconnected at the time. Terminal Sync and Session Monitor work together or independently.
Standalone or unified
Run Terminal Sync on its own as a lightweight, choose‑your‑own module, or alongside Silux Connect remote desktop, RMM and MDM. One agent, one bill, your choice.
How it works
Terminal Sync synchronizes terminal state and I/O, not video. A first‑party agent on the host owns the shell and a scrollback buffer; clients attach over an encrypted, token‑authenticated WebSocket relay (cloud or LAN). Because only tiny text streams over the wire, it stays responsive on 3G, satellite or the other side of the planet.
- Native apps for macOS, Windows and Linux, plus iOS/Android and a zero‑install web client.
- End‑to‑end TLS transport; per‑session connect tokens; role‑based access.
- LAN mode for zero cloud dependency; works air‑gapped.
- Multiple concurrent sessions per device, switchable as tabs — each with its own persistent host shell and scrollback.
- Single‑user, shared, and view‑only session modes.
One terminal. Every device. Anywhere on Earth.
Whether your fleet is in New York, London, Sydney, Singapore or São Paulo, Terminal Sync keeps a single source‑of‑truth shell that everyone on your team can reach — securely, instantly, and without losing a keystroke.
