Side by side. Honest as we know how.

Terminal Sync: persistent host shells attachable from Mac/Windows/Linux/iOS/Android/web that keep running if the connection drops — reconnect resumes the exact same session with full scrollback. Multiple concurrent sessions per device, switchable as tabs. Near-zero latency, copy/paste everywhere, offline-resilient, integrates with Session Monitor. The incumbents have no equivalent.

Silux syncs text and images between your machine and any remote, and remote-to-remote, with host copies landing in your clipboard automatically. Copying a file triggers a secure file transfer under the hood (no fragile cross-OS clipboard file semantics). Incumbents are largely text-only / same-OS.

All four implement E2E encryption; per-session key uniqueness and relay-zero-knowledge depth varies. Silux: per-connection ephemeral ECDH P-256 + HKDF-SHA256 salted with a per-session secret the relay never receives + AES-256-GCM on every frame, keystroke, file, terminal line and in-session clipboard message; unencrypted input refused once keyed.

Per-session unique key derivation from per-tenant KEK with relay-zero-knowledge documented for Silux Connect.

Silux Connect includes SSO on every paid plan from Starter ($29/tech/mo). Incumbents paywall behind enterprise add-on.

Silux Connect includes SCIM on every paid plan.

Required for admin accounts on Silux Connect by default.

TeamViewer mobile pack is a separately-priced add-on.

All vendors implement direct-touch in some form; full pointer-mode with absolute mapping is unique to Silux Connect.

Silux Connect syncs clipboard across all sessions in a tenant; incumbents are limited to 1:1 controller-to-host clipboard.

Silux Connect combines pinch-zoom + pan with a gyroscope-driven cursor on mobile. Incumbents offer pinch-zoom only, no gyroscope cursor.

Silux Connect degrades continuously with no hard bitrate floor and stays usable from ~150 kbps. Incumbents apply hard floors or freeze/disconnect on poor links.

RustDesk self-host gives operator regional choice; SaaS multi-region is narrower.

Silux Connect self-host is free with full feature parity.

Air-gapped on Silux Connect Enterprise.

AGPL-3.0 for both RustDesk and Silux Connect agent.

Silux Connect: from Solo ($4/mo), can run on local AI models; not on Free. TeamViewer: TeamViewer Intelligence (CoPilot, session summaries, Tia) on paid plans.

Session Monitor watches every terminal, build and browser session on the host continuously — even when no one is attached — and notifies when a run finishes, stalls or pauses (configurable idle window with escalation warnings), or the shell stops, even if you were disconnected at the time. No incumbent offers session-completion monitoring.

Silux Connect: from Solo ($4/mo); the video is saved on the technician's own computer, never on Silux servers.

Silux Connect Enterprise tier.

Silux Connect commits to publishing post-mortems for any incident with customer impact > 5 minutes.

Silux viewers keep the last picture on screen, detect half-open sockets with a 5-second app-level ping and a 15-second dead-link watchdog, probe the link within 3 seconds of any network change, and retry with jittered backoff (0.5s→8s) for up to 180 seconds without leaving the session. The agent on the remote computer also reconnects by itself in roughly 0.5–8 seconds when its own network changes. Competitor reconnect behaviour differs by version and platform.

The Silux viewer requests a full keyframe automatically on a decode error, a desynchronised stream, frames resuming after a stall, a reconnect, the remote computer rejoining, a resolution change, the tab or app returning to the foreground, and every 30 seconds while live — plus a manual Refresh button. Stale or corrupted tiles on poor links are repaired without user action.

Silux records a short clip, transcribes it server-side with a large speech model (Deepgram Nova-3, OpenAI gpt-4o-transcribe, Groq Whisper large-v3-turbo, AssemblyAI or a self-hosted Whisper server, with an optional backup provider) and converts spoken symbols — "ls dash la slash var slash log" becomes `ls -la /var/log`. Text is always shown for review before it is inserted or run. With other tools you can only use the local operating system's generic dictation, which does not convert shell syntax.

In Silux, Text mode dictation is punctuated and typed on the remote computer in one action, from the Silux Connect web app on any device. Other tools rely on the local operating system's dictation feeding keystrokes into the viewer.

The Silux admin Activity log shows a filterable, CSV-exportable timeline per user: sign-ins and failures, sessions, reconnects with downtime, lost links, network changes, auto-refreshes and voice-dictation use (character count only — never the spoken words). RustDesk's audit features depend on the server edition.

Silux Connect Solo $4/mo. RustDesk Server Pro ~$9.90/mo (annual only), AnyDesk Solo ~$14.90/mo, TeamViewer ~$24.90/mo (aggregator list prices, 2026).

Monitoring, alerts, scripting, patching and help-desk tickets for up to 20 devices on Free.

Opt-in per user; 20 messages/month on Free, more on paid plans.

Silux Connect adds virtual monitors on Windows (signed driver, installed on first use), macOS and Linux (private desktop when nobody is signed in).

Silux asks on every connect-by-ID + code session and declines when nobody answers; the workspace's own managed devices connect unattended unless the admin chooses 'ask every time'. AnyDesk: interactive-access setting; RustDesk: 'accept sessions via click'; TeamViewer asks only in some modes. Sources: support.anydesk.com/docs/settings, RustDesk 1.4.5 settings.

Silux: a third button on the accept prompt; the agent then injects no input and ignores control commands for that session (verified by automated test). AnyDesk lets the accept window toggle individual permissions; RustDesk's accept is all-or-nothing (view-only is a global access-mode setting).

Silux keeps favourites per user on the server (all plans). RustDesk favourites are stored locally (RustDesk_local.toml); its server address book needs RustDesk Server Pro. AnyDesk's address book requires a paid licence.

Silux: every agent reports its real MAC addresses; Wake up (or bulk Wake offline) picks up to three online agents on the same network to broadcast the packet, with live status, from a browser. TeamViewer and AnyDesk also wake through another of their clients on the network. RustDesk sends WOL only from the Discovered (LAN) list on the technician's own network.

Silux: per-computer passwords with a profile (keyboard, mouse, clipboard, files, terminal, sound, mic, restart, privacy, input lock, tunnels, printing, recording), enforced by the agent; a workspace default applies to every session. RustDesk: one permanent password plus a global access mode. TeamViewer: policies, not per-password rights.

Silux: a local page on the controlled computer (127.0.0.1, token-protected) with a timer per session, switches that can only restrict, and Disconnect; the technician is told at once. Plus an amber screen frame (Windows, macOS, Linux X11).

Silux: connect-by-code open to anyone, signed-in Silux users only, or an allow-list of emails, *@domain and IPv4/CIDR, checked before the code. AnyDesk: ACL of IDs/aliases; TeamViewer: block and allow list; RustDesk: IP whitelist.

Silux: AR camera assist opens from a QR code, link or 8-character code in Chrome/Safari; arrows, circles and labels stay on the object as the phone moves; ~150–250 kbps; nothing recorded. TeamViewer sells AR as Assist AR, a separate product. AnyDesk and RustDesk have no AR.

Silux does it from the technician's browser (WebRTC data channel, own STUN on the relay, no third-party servers) with a policy switch to force relay-only; the others need their desktop client.

Silux: HTTP CONNECT with login or SOCKS5, `silux-agent set-proxy`, honours HTTPS_PROXY / NO_PROXY.

Silux keeps every copy from every session in a pool; Paste puts it on the remote you are viewing, files go computer-to-computer through the sessions. Web, Windows/macOS/Linux app, iPhone/Android app.

Streaming speech-to-text shown in the session (Solo plan and up); not stored.

Silux: PowerShell as SYSTEM on Windows, bash on Linux/macOS, live output, end-to-end encrypted.
