Whether you’re an MSP looking to expand your toolkit or a solo IT professional managing a network, this guide will help you understand the current landscape of open source RMM software and how to choose the right one for your specific use case.
What Makes Open Source RMM Tools Attractive in 2025?
Cost Efficiency and Zero Licensing Fees
One of the biggest draws of open source RMM tools is that they are free to use and distribute. This makes them ideal for startups, educational institutions, and non-profits operating on tight budgets.
Customizability for Niche Requirements
Unlike proprietary software, open source RMM platforms can be customized to meet unique needs. From scripting integrations to UI modifications, the level of control is unparalleled.
Community-Driven Innovation
Most open source RMM projects are backed by active communities. These communities contribute to regular updates, plugin development, and rapid bug fixes—keeping the software relevant and secure.
Transparency and Data Ownership
With open source software, you retain full control over your data and infrastructure. There’s no risk of data harvesting or vendor lock-in, making it a secure choice for privacy-conscious organizations.
