What RMMZit does
Everything an IT department or service provider needs every day, for every Windows and Linux computer you manage.
Inventory
Hardware, operating system, disks, network, installed software, Defender, firewall and BitLocker state of every device, always current.
Monitoring and alerts
CPU, memory, disks, services, disk health, event logs, processes and network checks, with history and a disk-full forecast. Alerts by email, Slack, Teams or webhook.
Remote desktop
In the browser, for Windows and Linux: sign-in and UAC screens, several monitors, clipboard and file copy — no extra tool needed.
Terminal and files
PowerShell or a root shell in the browser, a file manager, processes and services, registry editor and scheduled tasks.
Scripts
PowerShell, cmd, bash and sh on one device or hundreds, at once or on a schedule, from your script library.
Updates and software
Windows updates and Linux packages, programs through winget and your own MSI/EXE library — by hand or on a schedule with update rings.
Policies
Updates, required and blocked software, restarts, maintenance windows, alert rules and BitLocker per customer, site or device.
Reports
Per customer: devices, updates, alerts and technician work, printable or emailed every week or month.
Why RMMZit
Your server, your network
No cloud service and no account with us. The console never has to be reachable from the internet; agents connect outbound, so managed computers need no open ports.
Secure by design
Separate ports for the console and the agents, commands signed by the server, pinned certificates, two-factor sign-in for every account and a hash-chained audit log.
Made for service providers
Customers, sites and devices; per-customer access for technicians; policies per customer; reports per customer; GPO and Intune rollout from every site page.
Light and fast
One server with 2 vCPU and 1 GB RAM handled 1,000 agents with about 200 MB of memory and 3 % CPU in our load test; after a restart all were back within 8 seconds.
In your language
The console, its built-in guide and the agent's tray window speak 14 languages: English, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Czech, Serbian, Turkish, Russian, Chinese and Japanese.
Free, with support if you want it
Open source under the AGPLv3, with no limits on devices, customers or technicians. Commercial support comes from MaxZit, the company behind RMMZit.
How it works
- The server is a small Linux VM (2 vCPU, 2–4 GB RAM, 16 GB disk) — a ready-made appliance or a package for Debian, Ubuntu, AlmaLinux and Rocky Linux, or a Docker container.
- The console (8443) accepts only your allowed networks, checked before TLS; the agent endpoint (8444) can be opened to the internet for computers at remote sites.
- Agents pin the server certificate when they enroll and run only commands signed by the server.
Running in minutes
Import the ready-made appliance — OVA for VMware, qcow2 for Proxmox/KVM, VHDX for Hyper-V — boot the appliance ISO, start the Docker image, or install on an existing Debian, Ubuntu, AlmaLinux or Rocky Linux server:
curl -fsSL https://github.com/Max-Zit/rmmzit/releases/latest/download/install.sh | sudo shThen open https://<server>:8443, enter the setup token and create the first administrator. Add a customer and a site, create an enrollment code and install the agents. All downloads and install options.
Frequently asked questions
Is RMMZit free?
Yes. RMMZit is free and open source under the GNU AGPLv3, with no limits on devices, customers or technicians. MaxZit offers optional commercial support.
Which computers can RMMZit manage?
Windows 10 and 11 and Windows Server 2016 and newer (64-bit), and Linux computers with systemd on x86-64 or ARM64 (Debian, Ubuntu, AlmaLinux, Rocky Linux and others). Remote desktop on Linux needs an X11 session.
Does RMMZit need the cloud or an open console on the internet?
No. You run the server in your own network. Only the agent port (8444) has to be reachable by computers outside your network; the console stays limited to your own networks.
Can I use RMMZit as an IT service provider for several customers?
Yes. Devices are grouped by customer and site, technicians can be limited to certain customers, every customer gets its own policies and reports, and the agent shows users who manages their computer.
How do I deploy the agent to many computers?
Create an enrollment code on a site. The site page shows a ready Group Policy startup script and the settings for a Microsoft Intune Win32 app; the MSI also installs silently from any script or RMM-style tool.
Can RMMZit install Windows updates and software?
Yes. It lists missing Windows updates and Linux packages and installs them by hand or on a schedule, with maintenance windows, update rings and restart deadlines. Programs come from winget, optionally Chocolatey, or your own MSI/EXE library.
Is remote desktop included?
Yes, in the browser for Windows and Linux (X11), including sign-in and UAC screens, several monitors, clipboard and file copy. An optional notice on the remote screen tells the user when someone is connected.
Is RMMZit an alternative to commercial RMM tools?
RMMZit covers the daily work of commercial RMM tools — inventory, monitoring, remote access, scripts, patching, software and reports — as a self-hosted, open-source product without per-device licenses.
