My Deep Dive into NetLockRMM: The Open-Source RMM You’ve Been Waiting For

Good morning everyone, I’m Dimitri Bellini, and welcome back to Quadrata, my channel dedicated to the fantastic world of open source and IT. If you’re managing multiple systems, you know the challenge: finding a reliable, centralized way to monitor and control everything without breaking the bank. Proprietary solutions can be costly, and the open-source landscape for this has been somewhat limited.

That’s why this week, I’m excited to show you a new product that tackles this problem head-on. It’s an open-source tool called NetLockRMM, and it’s designed to solve the exact problem of remote device management.

What is NetLockRMM?

NetLockRMM stands for Remote Monitoring and Management. It’s a self-hosted solution that gives you a single web portal to manage and control your remote hosts. Whether you’re dealing with servers or desktops running Windows, Linux, or macOS, this tool aims to bring them all under one roof. For those of us who use tools like Zabbix to manage numerous proxies or server installations, the idea of a single point of control is incredibly appealing.

Here are some of the key features it offers:

• Cross-Platform Support: Agents are available for Windows, Linux, and macOS, covering most use cases.
• System Monitoring: Keep an eye on vital parameters like CPU, RAM, and disk usage. While it’s not a full-fledged monitoring system like Zabbix, it provides a great overview for standard requirements.
• Remote Control: Access a remote shell, execute commands, and even get full remote desktop access to your Windows machines directly from your browser.
• File Transfer: Easily upload or download files to and from your managed hosts.
• Automation: Schedule tasks and run scripts across your fleet of devices to automate maintenance and checks.
• Multi-Tenancy: Manage different clients or departments from within the same instance.

Getting Started: The Installation and Setup Guide

One of the best parts about NetLockRMM is how simple it is to get up and running. Here’s a step-by-step guide to get you started.

Prerequisites

All you really need is a system with Docker installed. The entire application stack runs in containers, making deployment clean and isolated. If you plan to access the portal from the internet, you’ll also need a domain name (FQDN).

Step 1: The Initial Installation

The development team has made this incredibly easy. The official documentation points to a single Bash script that automates the setup.

1. Download the installation script from their repository (https://docs.netlockrmm.com/en/server-installation-docker).
2. Make it executable (e.g., chmod +x /home/docker-compose-quick-setup.sh).
3. Run the script. It will ask you a few questions to configure your environment, such as the FQDN you want to use and the ports for the services.
4. The script will then generate the necessary docker-compose.yml file and, if you choose, deploy the containers for you.

While you can easily manage the deployment from the command line, I’m getting quite fond of using a handy container management tool to deploy my stacks, which makes the process even more convenient.

Step 2: Activating Your Instance

Here’s an important point. While NetLockRMM is open-source, the developers have a fair model to support their work. To fully unlock its features, you need to get a free API key.

1. Go to the official NetLockRMM website and sign up for an account.
2. Choose the On-Premise Open Source plan. It’s free and allows you to manage up to 25 devices, which is very generous for home labs or small businesses.
3. In your portal dashboard, navigate to “My Product” to find your API key.
4. In your self-hosted NetLockRMM instance, go to Settings > System and paste the Member Portal API Key.

Without this step, the GUI will work, but you won’t be able to add any new hosts. So, make sure you do this first!

Step 3: Deploying Your First Agent

With the server running and activated, it’s time to add your first machine.

1. In the NetLockRMM dashboard, click the deployment icon in the top navigation bar.
2. Create a new agent configuration or use the default. This is where you’ll tell the agent how to connect back to your server.
3. This is critical: For the API, App, and other URLs, make sure you enter the full FQDN, including the port number (e.g., https://rmm.yourdomain.com:443). The agent won’t assume the default port, and it won’t work without it.
4. Select the target operating system (Windows, Linux, etc.) and download the customized installer.
5. Run the installer on your target machine.
6. Back in the NetLockRMM dashboard, the new machine will appear in the Unauthorized Hosts list. Simply authorize it to add it to your park of managed devices.

Exploring the Key Features in Action

Once an agent is authorized, you can click on it to see a wealth of information and tools. You get a summary of the OS, hardware specs, firewall status, and uptime. You can also browse running processes in the task manager and see a list of services.

Powerful Remote Control

The remote control features are where NetLockRMM truly shines. For Windows, the remote desktop access is fantastic. It launches a session right in your browser, giving you full GUI control without needing any other software. It’s fast, responsive, and incredibly useful.

For Linux, the remote terminal is currently more of a command-execution tool than a fully interactive shell, but it’s perfect for running scripts or a series of commands. You can also browse the file system and transfer files on all supported platforms.

Automation and Scripting

The automation section allows you to create policies and jobs that run on a schedule. You can define checks for disk space, running services, or even script your own checks. There’s also a growing library of community scripts you can use for common tasks, like running system updates on Ubuntu.

My Final Thoughts: A Promising Future

NetLockRMM is a young but incredibly promising project. It’s under very active development—when I checked their GitHub, the last release was just a few days ago! This shows a dedicated team working to improve the product.

It fills a significant gap in the open-source ecosystem, providing a powerful, modern, and easy-to-use RMM solution that can compete with paid alternatives. While there are a few cosmetic bugs and rough edges, the core functionality is solid and works well.

I believe that with community support—through feedback, bug reports, and contributions—this tool could become something truly special. I’ve already given them a star on GitHub, and I encourage you to check them out too.

I hope I’ve shown you something new and interesting today. This is exactly the kind of project we love to see in the open-source world.

But what do you think? Have you tried NetLockRMM, or do you use another open-source alternative for remote management? I’d love to hear your thoughts and recommendations in the comments below. Every comment helps me and the rest of the community learn.
