Delta — remote desktop

Take the screen.Leave the record.

Delta hands you the far machine: its screen, its files, its clipboard. Sessions are encrypted end to end, and when the network will not let two machines speak directly, the relay that carries them is ours, inside the EU. The host keeps its own log of every file that moved.

The Delta client on Linux: the device ID marked ready, and a field to connect to a peer.
Delta on Linux — a screenshot, not a mockup

Measured, not claimed

Four things you can check.

Session cipher
XSalsa20-Poly1305

A symmetric key is agreed per session. Relays forward ciphertext and hold no key that opens it.

Identity
Ed25519

The rendezvous server signs each peer’s identity. The client verifies that signature against the key built into it before a single pixel moves.

When verification fails
The session is refused

Not downgraded, not retried in the clear. The client aborts — because a client that falls back to plaintext is a client that can be pushed into plaintext.

Rendezvous and relay
relay-eu1.altovar.net

Our own machines running our own image, inside the EU. Point the client at a different one and it will use that instead.

One client, the whole call.

One client, the whole call.

One call, without changing tool: you see the screen, you move the files, you switch monitor, you sort it out in the chat. Everything on this rail is in the Linux client you can download — nothing here is a roadmap.

  • Remote control

    The far screen with its keyboard and mouse, in a window or full screen, with frame rate and codec in view as you work.

  • Multi-monitor

    Pick which of the host’s displays you are looking at, and switch during the session without reconnecting.

  • File transfer

    A dual-pane browser with a queue, moving files both ways during the session.

  • Host-side file audit

    The host gets its own panel naming every file read off the machine or written to it, with the path and the direction.

  • Clipboard sync

    Text follows the clipboard between the two machines, with a history panel on your side — and the host decides, per connection, whether it is shared at all.

  • Remote audio

    What plays on the host plays for you too, inside the same session — and the host can leave audio out when accepting.

  • Port forwarding

    Forward a local TCP port to the remote machine and reach a service that was never exposed.

  • Chat

    A message channel running alongside the session, for whoever is sitting at the other end.

  • LAN discovery

    Finds other Delta devices on the same network by broadcast, without involving the relay at all.

Walk a session

AI, only with consent

A copilot that watches with you.

Delta can read a session the way a senior colleague would: it looks at the screen, understands what is going wrong, and says what to try next. All of it is optional — and all of it goes through our gateway in the EU.

Live suggestions
During a session the copilot takes a frame every 8 seconds — only when the screen actually changes — and puts the next step in a side panel.
Reads the error for you
One click captures the screen, reads the text on it, pulls out the error and proposes a fix.
Reports and key moments
A recorded session can become a written report, with errors and state changes marked on the timeline automatically.
Before, and after
Take a reading of the machine, do the work, take another — and what changed between the two comes back written out.

Every analysis goes through ai.altovar.net, our gateway in the EU. Point the client at your own gateway if you prefer.

How the copilot works

The handshake

It refuses before it downgrades.

The client checks the peer, then agrees a key. Fail that check and there is no session — not a weaker one.

Your client Rendezvous The peer How the handshake works

The path stays in Europe.

A support call is a connection between two machines, and someone has to carry it when the network will not let them speak directly. That carrier is the part most remote tools are quiet about.

Direct first
Delta tries a direct peer-to-peer connection and falls back to the relay only when the network refuses. Fewer hops whenever the ports allow it.
Our hardware, in the EU
When the relay is needed it is relay-eu1.altovar.net: our machines, running an image we build, inside the EU. Nobody else sits in the middle of your support call.
Or your own
Point Delta at a rendezvous and relay you run, and it talks to your infrastructure instead of ours.

What this does not do yet

Straight about the gaps.

The rest of the page is only as believable as this list.

A remote terminal

The Linux host we ship always refuses a terminal. There is no UI that grants one.

Privacy mode on Linux

Privacy mode is Windows and macOS. The Linux build drops it.

Voice commands

The bundled webview has no SpeechRecognition. The control is not on the build you can download.

A knowledge base that writes

Generating an article from a recording has no caller outside tests. There is nothing to search.

Delta is one of ours.

It shares its identity layer, its relays and its European footprint with the rest of the Altovar catalogue. One supplier, one place to ask, one jurisdiction.
