Closed beta in progress. Want to join?
One Nythronix to rule them all.
Nythronix is a control plane for remote servers and workstations. Browser terminals, SSH through a relay, and AI assistants for machines behind NAT. Run it yourself or use our hosted service.
One installer for the whole Windows family, from 7 SP1 to 11, 32-bit and 64-bit. On Linux, use the installation script from the dashboard. Quickstart documentation.
What it can do
These features are already working and are what we are testing in the closed beta.
- Terminal in your browser
Sessions survive through tmux or zellij: close the tab, lose the network, or restart the agent, and your command keeps running.
- Linux and Windows agents behind NAT
The agent opens an outbound connection to the control plane. No inbound ports, VPN, or public IP addresses required.
- SSH relay through the control plane
SSH and scp tunnels between machines and from the operator's laptop. Encryption stays end to end; the control plane cannot read the traffic.
- Access by consent code
For someone else's machine: the owner generates a single-use code and the operator enters it in the dashboard. Codes expire and access can be revoked, as in TeamViewer.
- AI workers in channels
Channels for machines and tasks, like Discord. Workers read, suggest, and run commands, but changes require human approval and are recorded in the audit log.
- Skills through MCP
Connect Postgres, web tools, and other ready-made MCP servers as worker skills. Each runs on its own machine with restricted network access.
- Signed updates
Agent releases are signed with Ed25519. The agent verifies the signature and updates itself, without a manual visit to every machine.
- An unprivileged agent and on-demand sudo
The agent runs as a regular user. Elevated permissions are granted for specific commands and a limited time.
How it works
Three steps from a fresh machine to a terminal.
- Install the agent
Use the installer on Windows or the script on Linux. Enter a single-use enrollment token, and the agent connects to the control plane automatically.
- The machine appears in the dashboard
See its online status, OS, and version at a glance. Organize machines with tags:
client:acme,env:prod. - Terminal, SSH, or AI
Open a browser session, forward a port through SSH, or add the machine to a channel with a worker.

Windows agent
The installer asks for the control plane URL and an enrollment token, and can optionally install OpenSSH Server. One file covers Windows 7 SP1 and Server 2008 R2 through Windows 11, both 32-bit and 64-bit.
