Team chat tools sit at the center of day-to-day coordination, so the main question is simple: which products are healthy, actively shipping, and still trusted by users for May 2026. This section is based on the ToolVitals dataset for the Team Chat use case.
The ranking uses ToolVitals score first, with GitHub stars as a secondary popularity signal when scores are tied. That keeps the ordering focused on product quality and momentum, while still reflecting broader adoption.
