Customer support teams comparing self-hosted or source-visible options need to separate active projects from old ticketing systems that still have name recognition. For June 2026, this section uses the supplied ToolVitals data for Customer Support Tools, including ToolVitals score, health score, shipping score, GitHub stars, status, openness_label, and license_label.
The ranking is limited to open/source-visible tools and is ordered by ToolVitals score first, with GitHub stars used only as a secondary popularity signal when scores are tied. Every listed tool in this data is labeled OSI-approved OSS, with license_label values such as MIT, AGPL-3.0, Apache-2.0, LGPL-2.1, GPL-2.0, GPL-3.0, and OSL-3.0.
