Choosing notes and knowledge base software is mostly a trust problem: the tool has to keep shipping, stay healthy, and fit the way people capture, connect, and retrieve information. For May 2026, this ToolVitals view compares 37 notes and knowledge base tools using the supplied health, shipping, GitHub star, status, and ToolVitals score data.
The ranking is ordered by ToolVitals score from highest to lowest, with GitHub stars used only as a secondary popularity signal when scores need context. That means a smaller project with stronger current health and shipping signals can rank ahead of a more popular project with weaker overall ToolVitals data.
