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 Open WebUI if
- You want the more widely adopted option (adoption 80).
- You rely on thorough README docs (docs 69 vs 29).
Pick llama.cpp if
- Recent activity and releases matter most to you (maintenance 83).
- You need a permissive open-source licence (MIT).

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.
