Top 50 Team Chat Tools — April 2026

Team chat tools in April 2026 were led by a small cluster of highly rated projects, with several entries scoring a perfect 100 on ToolVitals. The data points here reflect each tool’s ToolVitals score, health score, shipping score, GitHub stars, and status as supplied for this period.

The ranking here follows ToolVitals score first, then GitHub stars as the secondary popularity signal when scores are tied. That means the top slots favor tools that are both strong on the dataset’s core score and widely adopted, rather than popularity alone.
