Git hosting and code collaboration platforms for pull requests, code review, and CI integration. Right now, GitHub is the brand AI assistants recommend most, with a Visibility Score of 88 and the #1 spot in 88% of answers. Head-to-head: GitHub vs GitLab →
These rankings are measured from what the three models know from training, not a live web search. When the models DO search the web, see which sources they cite. Methodology.
GitLab and GitHub trade blows with no separator between them.
A 1.5-point gap separates GitLab and GitHub at the top, yet the two brands tell opposite stories: GitHub converts 78% of its mentions into first-pick position while GitLab converts under 6%, meaning GitLab shows up more but rarely leads the recommendation. Bitbucket sits in a strange middle ground, mentioned in 81% of answers but never chosen first, making it a persistent also-ran. Azure DevOps scores just 30 overall and gets its strongest signal from Gemini at 40, suggesting even its best case is weak visibility.

The ± under each score is the reliability band: how much the number would move if we re-ran the identical measurement. It is tight because each prompt is sampled multiple times. It is not the same as how much the ranking depends on which prompts we ask — a separate, wider figure shown on hover.
Just below the cutoff: Jira (1.8), CircleCI (1.8), Jenkins (1.8), GitLab Enterprise (1.3), Dependabot (1.1). 41 brands were scored in this category; the leaderboard shows the top 15.
Visibility Score: position-weighted presence across all measured answers, 0 to 100. A score of 100 means the brand was the first recommendation in every answer. Every point in a trend line is a live monthly measurement; there is no modeled or backfilled history. Full methodology.
Openness 13/100: the share of this category's recommendation weight not held by the leader.
