What this does not tell you
Scores are percentiles of public GitHub signals. Nobody here tested these tools hands-on, so the higher score is not a verdict on which suits your project. Yellow marks the higher value.
Which one fits you
From measured data and licences, not from testing.
Pick Ollama if
- Recent activity and releases matter most to you (maintenance 67).
- You want the more widely adopted option (adoption 81).
- You need a permissive open-source licence (MIT).
Pick Open WebUI if
- No measured signal where it leads all the others.

Why different labels?
A label partly reflects how much of each tool is visible and scannable, not only how risky it is. A tool without a lockfile cannot get a dependency check.
