IT asset management and CMDB buyers need to distinguish broad service-management platforms from narrower infrastructure-discovery tools. ToolVitals uses project health, shipping activity, openness, licensing, and GitHub popularity data to compare five source-visible options for July 2026.
The ranking includes only open or source-visible tools and orders them by ToolVitals score, with GitHub stars used as a secondary popularity signal for ties. The supplied scores and ordering are retained without adjustment.

Top 3 Highlights
Scanopy ranks first with a ToolVitals score of 91, a health score of 84, and the strongest shipping score in this group at 93. Its current site positions it as living network documentation: a scanner discovers hosts, maps Layer 2 and Layer 3 topology, and documents services, dependencies, and workloads. This makes it the most specialized choice in the top three rather than a full IT service-management suite. It is OSI-approved OSS under AGPL-3.0.
GLPI ranks second with a ToolVitals score of 89, a health score of 85, and a shipping score of 86. Its current first-party positioning covers service desk, asset management, CMDB, data-center management, and dynamic inventory, giving it the broadest operational scope among the top three. Its 6,172 GitHub stars are the highest in this ranking, although stars are only a secondary signal. It is OSI-approved OSS under GPL-3.0.
iTop ranks third with a ToolVitals score of 88, a health score of 86, and a shipping score of 81. Combodo describes the CMDB as the core of the platform and connects it with service catalogs, request and incident handling, change management, automation, integrations, and low-code customization. That combination makes iTop a CMDB-centered ITSM option rather than a standalone asset register. It is OSI-approved OSS under AGPL-3.0.
