Platform Information

OpenMSP is currently community-supported. We focus on providing value to the MSP community first. Any future monetization will keep the core platform free for MSPs while maintaining our independence and commitment to unbiased information.
We focus exclusively on MSP needs with transparent vendor information and open-source alternatives. No vendor partnerships or sponsored listings - just honest, community-driven information to help MSPs make better technology decisions. Our biggest value is our community where MSPs help each other with questions, setup guidance, and sharing real-world experiences.
Our community of MSP professionals helps verify and update information. We also maintain direct research on tools and vendors to ensure accuracy. Community members can report outdated information, and we work to keep everything current.
OpenMSP was founded by Michael Assraf, who has extensive experience in the MSP industry and product leadership. As the former CEO & Founder of Vicarius, Michael grew a startup from $0 to $9M ARR with 500+ customers and deep experience working with MSPs, partners, and fundraising.

Open-Source Tools & Alternatives

We assess tools based on active development, community size, documentation quality, production deployments by MSPs, and available support options. Tools must meet strict criteria for reliability and enterprise readiness.
Many open-source projects offer multiple support options including community forums, commercial support from vendors, professional services, and our community discussions where experienced MSPs share implementation guidance.
