Agentless command center for your Linux servers. Connect over SSH for live monitoring, a full remote desktop with file manager, terminal and code editor, smart alerts and an AI ops copilot. Nothing runs on your servers, nothing leaves your machine.
A startup from France that is founded by David Christian.
This page is designed to help you find out whether Termal OS is good and if it is the right choice for you.
Your Linux servers, as a desktop. Termal OS turns your whole fleet into a real desktop over SSH - live monitoring, files, a terminal, a code editor, a browser and an AI ops copilot, with nothing to install on your servers.
All it takes is SSH access - shared (mutualized) hosting, a VPS or a dedicated server, no root required. Agentless and local-first: your data and credentials never leave your machine.
What's inside: Live monitoring - CPU, memory, disk, network, load and processes in real time, with history and anomaly detection. Remote desktop - SFTP file manager, a real PTY terminal, a Monaco code editor and a multi-tab browser, all over one reusable SSH connection. Sites & Docker - hosted sites with their real PHP version (cPanel, Plesk, Infomaniak, nginx/Apache) and Docker containers with live stats. Smart alerts - per-server thresholds and escalation to Telegram, Slack, Discord, a webhook or email. AI ops copilot - ask in plain language, get a command with an explanation. Nothing runs until you click. Bring your own API key (Anthropic, OpenAI, Mistral, Groq or a local model).
Free forever for 1 server and 1 user. During the Preview, manage up to 3 servers at no cost.
Listed in
Agentless SSH connection
Connects over the SSH access you already have, by password or private key. Nothing is installed on the monitored server: no daemon, no package, no inbound port. It works on shared and managed hosting too.
Live monitoring
CPU per core, memory, swap, disks, network, load, processes and TCP connections, polled at the interval you choose. 60 seconds by default, 15 seconds minimum.
History and anomaly detection
Keeps a short rolling window of metrics in a local SQLite database, 24 hours by default, with z-score anomaly scoring on top of it.
Smart alerts
Per-server warning and critical thresholds on CPU, memory, disk and load, with escalation and notifications to Telegram, Slack, Discord, webhooks or email.
SFTP file manager
A full file explorer with real progress reporting: upload, download whole folders, handle archives and edit permissions.
Terminal and live logs
A genuine PTY shell inside the app, plus live tail -F log streaming, on the same SSH connection.
Remote desktop over SSH
A window manager, a multi-tab browser and a process manager, all driven through one reusable SSH connection. It is a workspace, not an RDP or VNC protocol.
AI ops copilot
Ask in plain language and get a command with an explanation. Nothing runs until you click. Bring your own API key: Anthropic, OpenAI, Mistral, Groq or a local model.
Hosting stack detection
Recognises Ubuntu, Debian, nginx, Apache, PHP, MySQL, Redis, Docker, Plesk and cPanel. Lists hosted sites with the PHP version each one actually runs, turns access logs into visit statistics and offers a one-click git pull.
Docker containers
Lists and manages Docker containers on the servers you connect to.
Roles and access control
Admin, operator and viewer roles, with per-server access control.
Local-first by design
Credentials are encrypted on your machine with AES-256-GCM and never leave it. Metrics stay in a local SQLite database. No cloud backend holds your server data; a termalos.com account only validates your license.
Published SHA-256 checksums
Every release publishes the fingerprints of its installers, on termalos.com and as a per-version JSON manifest, so you can verify any copy you downloaded.
Most tools make you choose. A monitoring system tells you a disk is filling up, then you open a separate SSH client to do something about it. Termal OS does both in the same window, and it does it without installing anything on the server.
It connects over the SSH access you already have, by password or private key. No agent, no daemon, no package, no inbound port. That is not a preference, it is what makes it usable on shared and managed hosting, and on a client's server that is not yours to modify.
The other half is where the data lives. Termal OS is a desktop application, not a SaaS. Metrics go into a SQLite database on your own machine, credentials are encrypted locally with AES-256-GCM, and no server of ours ever sees your fleet. A termalos.com account exists only to validate a license.
Put together: you see the problem and you fix it in the same place, on servers you never had to prepare, with telemetry that never left your desk.
Often they should not, and the site says so on its own comparison pages. If you run hundreds of machines, need years of retention, distributed tracing or log search, then Zabbix, Netdata or Datadog are the right answer and Termal OS is not. That is written on termalos.com before anyone downloads anything.
The case for Termal OS is narrower and it is real. You have a handful of Linux servers, up to a few dozen. Standing up a monitoring server, a database and a frontend is more machinery than the problem deserves, or you have tried twice and given up both times. Some of those machines are not yours to install software on. And you spend as much time administering them as watching them.
For that person, three things change. There is no infrastructure to run, so there is no monitoring system that can itself fail at three in the morning. Adding a server is one form with the SSH details you already use, not a template to wire up. And when something breaks, the file manager, the terminal and the code editor are already in the window you are looking at.
Solo developers, freelancers and small web agencies who run their own Linux servers, plus the people who look after a handful of servers for clients.
Concretely: someone with two to twenty machines, a mix of VPS, dedicated boxes and shared or managed hosting, running websites, APIs and a few services. They have SSH access everywhere and root on only some of it. They are the person who gets called when a site goes down, and they are also the person who fixes it.
It is deliberately not built for platform teams, on-call rotations or fleets of hundreds. There is no SNMP, no Windows agent, no Kubernetes and no network discovery. Every comparison page on the site says this plainly, because the wrong user is worse than no user.
Termal OS started as a personal tool. I am an independent developer in the south of France, and like a lot of people who build and host their own projects, I ended up with servers scattered across a VPS, a dedicated box and managed hosting, none of them alike.
Every option I looked at asked for something I did not want to give. Install an agent on machines I do not fully control. Stand up a server, a database and a frontend to keep an eye on three VPS. Or send my servers' telemetry to somebody else's cloud and pay per machine per month.
So I built the thing I actually wanted: one desktop application that connects over the SSH I already had, shows me what is happening, and lets me fix it without switching windows. The remote desktop came out of that, because half the work was never monitoring in the first place. It was opening a log, editing a config and restarting a service.
It is in public Preview today, built by one person, and free while it finds its shape.
Termal OS is an Electron desktop application, so the same codebase ships on Windows, macOS and Linux. Node.js does the work underneath.
Everything server-side goes through ssh2, which handles both the SSH shell and the SFTP transfers over a single reusable connection. That is the whole reason nothing has to be installed on the monitored machines: every metric comes from reading /proc and running standard shell tools over that connection.
Metrics and history live in a local SQLite database through better-sqlite3, on the user's own machine. The code editor is Monaco, the same engine as VS Code. An internal Express and WebSocket layer carries live streams to the interface, which is plain HTML, CSS and JavaScript bundled with esbuild, with no frontend framework.
The AI copilot has no model of its own. You bring your own API key, for Anthropic, OpenAI, Mistral, Groq or a local model, and nothing is resold.
We have collected here some useful links to help you find out if Termal OS is good.
Check the traffic stats of Termal OS on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Termal OS on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Termal OS's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Termal OS on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.
