Customer support teams looking at open-source and self-hosted options face a mixed field in May 2026: some projects show strong current activity, while many recognizable names have weaker shipping signals in this dataset. ToolVitals compares each tool using health, shipping activity, GitHub stars, and an overall ToolVitals score so readers can separate active projects from ones that may need closer review before adoption.
The ranking is ordered by ToolVitals score descending, with GitHub stars used only as a secondary tie-breaker when scores are close or equal. That means active project health and shipping behavior drive placement first, while stars are treated as a popularity signal rather than proof that a tool is currently well maintained.

Top 3 Highlights
clientst0r ranks first with a ToolVitals score of 87, supported by the strongest combined profile in the list: a 91 shipping score, an 84 health score, and 59 GitHub stars. Its scope is also broad for customer support operations, covering tickets, projects, a knowledge base, invoices, and a customer portal in a self-hosted MSP platform.
dograh ranks second with a ToolVitals score of 86 and the highest shipping score in the dataset at 100. It also has 446 GitHub stars, giving it a stronger popularity signal than most of the other high-scoring tools, though its listed scope is narrower as an open-source voice agent platform.
InteraOne ranks third with a ToolVitals score of 81, an 82 health score, and an 80 shipping score. Its description points to a broader support-and-sales automation product, making it one of the higher-ranked options with an end-to-end customer support positioning rather than a single-channel or narrowly focused tool.
