CMai OS is a licensed operating system you install on an always-on server. The CMai API — one key, every model — is ready in every user's workspace: cmai launches the CMai CLI, and Claude Code, Gemini CLI and Kimi CLI come preinstalled too. Everyone works in their own isolated workspace, and projects go live on the server's own domain.

cmai commandWrite the ISO, boot it, finish the wizard in your browser. The rest is SSH.
Put the ISO on a USB stick or into a virtual machine. The install is unattended: it takes the whole disk, asks nothing, and finishes in a few minutes.
On first boot a card appears on the console: https://<ip>:8443 and a one-time setup code. In the browser, enter your licence key, your CMai API key and your admin account.
ssh <admin>@<ip> drops you straight into your isolated workspace. cmai (or cmai code) starts the CMai CLI on the CMai API; claude, gemini and kimi are right there too.
Your project goes live on an automatic subdomain of the server's domain, with a TLS certificate. Applications build into distributable packages.
CMai API — one key, every model: the single CMai key you enter in the wizard is written into every user's workspace; cmai (or cmai code) starts the CMai CLI on cmai-pro — with automatic memory, skills, sub-agents and MCP support; cmai-balanced, cmai-fast and cmai-vision are selectable. CMai is the enterprise AI platform built by CMApps: chat, image, audio-video and embeddings behind one standard API, with credit management and live monitoring at app.cmai.tr. Claude Code · Gemini CLI · Kimi CLI are installed and ready, with your own account.
Every user gets their own rootless-podman workspace, with CPU, RAM and disk quotas per user. One person's build never slows another's.
When a project is published, a subdomain opens under the server's domain and its certificate is issued automatically. No DNS or reverse-proxy work.
Applications compile on the server and turn into distributable packages. The development environment and the production artifact live on the same machine.
The key binds to the server and is verified online. If the licence becomes invalid the server enters lock mode and preserves your data; a new key reopens it without a reinstall.
All traffic is encrypted with TLS 1.2+/1.3, and licences and updates are Ed25519-signed (AES-256 / Ed25519 / TLS 1.3). SSH is key-only, the nftables firewall is default-deny and fail2ban is on; keys stay on the server, root-only.
The server's :8443 panel shows the licence, the device and the connection; from the console the admin CLI sudo cmai … does the same jobs.
Same ISO, same commands — only the number of users and servers changes.
Work should not stop when your laptop closes. Long CMai CLI and Claude Code sessions, builds and test runs keep going on the server, and you check in over SSH from your phone. Your projects are live on your own domain right away.
An isolated, quota-bound workspace for every developer; one server, one invoice. Nobody can break anybody else's environment, and a new joiner is one command away: sudo cmai user add ayse --cpus 2 --mem 4096.
Code and data stay in your own data centre; only licence status leaves it. Multiple servers are governed by a single key policy, and suspension or revocation takes effect within seconds.
CMai OS is not a cloud service — it is an operating system you install on your own server. You feel the difference most in setup time and in maintenance.
| CMai OS | Hand-built VPS | Cloud IDE (Codespaces etc.) | |
|---|---|---|---|
| Time to ready | Write the ISO, boot, run the wizard: ~15 min | Hours: OS, users, containers, reverse proxy, TLS, AI tooling | Minutes |
| CMai · Claude Code · Gemini CLI · Kimi CLI | Preinstalled and ready for every user; CMai API gives every model from one key | Install by hand, track versions and keys yourself | Usually an extension or a manual install |
| User isolation | Rootless podman + quotas, by default | Design it yourself (LXC/Docker/sudo rules) | A separate environment per user (priced separately) |
| Publishing projects | Automatic subdomain + TLS | DNS + Caddy/Nginx + certificates | Port forwarding / temporary links |
| Where code and data live | Your server; only licence status leaves it | Your server | The provider's cloud |
| Always on | Yes — work continues with the laptop closed | Yes | Sleeps when idle / time limited |
| Maintenance and updates | cmai update apply, pick a channel | Entirely on you | On the provider |
| Licence / cost model | Per-server licence: Solo $29/mo, Team $99/mo (5 users included); the server is yours | Server cost only, plus your own time | User × hour, or a monthly per-user subscription |
Prices are monthly, in USD and exclude VAT. AI usage is not included: CMai API credits come from app.cmai.tr, and Claude Code · Gemini CLI · Kimi CLI run on your own account. The trial is free for 14 days.
Solo and Team licences are bought over email for now; the key arrives by email after payment, and online checkout (iyzico / Stripe) is coming. The key format is CMAI-XXXX-XXXX-XXXX-XXXX; one key binds to one server, and when you move servers the old device is released at portal.cmaios.com. Moving from Trial to Solo or Team is just a matter of entering the new key; users can be added to Team at any time and the remaining term is prorated.
sudo cmai ….nftables firewall is default-deny and fail2ban blocks repeated attempts. SSH stays fully closed until setup is finished.CMai OS is a licensed development server operating system you install on an always-on server: our own Linux distribution for AI development servers, with its own kernel configuration, a signed update channel and its own ISO. It ships with the CMai API (one key, every model) plus Claude Code, Gemini CLI and Kimi CLI; every user works in their own workspace isolated by rootless podman, and projects are published on an automatic subdomain of the server with TLS.
Yes. CMai OS is our own Linux distribution, built by CM Apps for AI development servers: it comes with its own kernel configuration, its own ISO and an Ed25519-signed update channel (stable · beta · nightly). Only amd64 is supported.
Military-grade encryption standards: all traffic is encrypted with TLS 1.2+/1.3, and licences and updates are signed with Ed25519 (AES-256 / Ed25519 / TLS 1.3). SSH works with keys only, and password login is switched off automatically once a key is added; the nftables firewall is default-deny and fail2ban blocks repeated attempts. Every user works in an isolated rootless workspace (read-only rootfs, cap-drop ALL, no-new-privileges, quotas); keys stay on the server in root-only files.
The server needs to reach the licence service (license.cmaios.net) regularly; short outages do not affect anything. If the connection cannot be made for a long time the server enters lock mode, and it reopens by itself when connectivity returns.
The key is bound to one device. On the old server, unbind it with "cmai license deactivate" or release the device at portal.cmaios.com, then use the same key on the new server, either in the wizard or with "cmai license activate".
Everything stays on your server; CMai OS never sends code or data out, and the licence service only ever sees the key and the device status. In lock mode the services stop but the disk is untouched; enter a new key and you carry on where you left off.
Four: CMai · Claude Code · Gemini CLI · Kimi CLI. CMai is the enterprise AI platform built by CMApps — chat, image, audio-video and embeddings behind one standard API, with credit management and live monitoring. It runs on the CMai API: you take one key from app.cmai.tr/customer/keys and enter it in the wizard, the key is written into every user's workspace, and the "cmai" command (or "cmai code") starts the CMai CLI, the CMai coding agent that lives in your terminal, on the cmai-pro model (cmai-balanced, cmai-fast and cmai-vision are selectable): automatic memory, skills, sub-agents and MCP support; cmai -p "…" runs a one-shot command, and a CMAI.md at the project root gives it standing instructions. Claude Code (Anthropic), Gemini CLI (Google) and Kimi CLI (Moonshot) are installed in every workspace too; you sign in to them with your own account or API key. Claude Code does not run through CMai; it needs an Anthropic account.
We recommend 8 vCPU, 32 GB RAM and 500 GB NVMe to start. A single-user trial runs on a 2 vCPU / 4 GB / 40 GB virtual machine; for team installs, size the machine by adding up the quotas you plan to give each user. Only amd64 is supported.
No. The install is unattended and takes the whole of the selected disk. Install it in a virtual machine or on a server dedicated to the job; both BIOS and UEFI are supported.
Any environment with amd64: VirtualBox, VMware, Proxmox, KVM/QEMU, Hyper-V, and VPS providers such as Hetzner, DigitalOcean and OVH via a custom ISO. Set networking to bridged, or give it a public IP, so you can reach the :8443 panel from your browser.
As many as your licence allows. Trial and Solo are single-user, Team covers 5–20, and Enterprise covers 20+ users across several servers. Users are added with "sudo cmai user add <name> --cpus N --mem MB --ssh-key ..."; each gets their own workspace with quotas.
The trial is free for 14 days. Solo is $29/mo (1 user, 1 server). Team is $99/mo with 5 users included, $19/mo per extra user, up to 20 users on one server. Enterprise (20+ users, multiple servers, priority support) starts at $499/mo per server and is quoted. Prices are monthly, in USD, excluding VAT. To buy, write to isgelistirme.ortaklik@cmapps.com.tr and your licence key arrives by email after payment; online checkout (iyzico / Stripe) is coming. Renewals and device management are handled at portal.cmaios.com.
No. The CMai OS licence covers the operating system, the isolated workspaces, publishing and updates; AI usage is separate. CMai API usage is drawn from your CMai credits at app.cmai.tr, and Claude Code, Gemini CLI and Kimi CLI run on your own subscription or API key (BYOK). That is why the licence is priced to be a small fraction of the AI usage you are already paying for.
On the server, with "cmai update check" and "cmai update apply"; the channel can be stable, beta or nightly. New versions are also published as ISOs at releases.cmaios.net, and "cmai license status" shows the installed version.
Sessions survive a closed laptop, long builds and test runs are never cut off, several people work on the same project each in their own isolated environment, and the result publishes straight from the same server. You install no tools or dependencies on your local machine; all you need is an SSH client.
