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 80 and the #1 spot in 79% 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. The live-web grounded surface is rolling out across the index. Methodology.
GitHub owns first pick; GitLab wins mentions but loses the moment.
GitHub is named first 79% of the time despite appearing in fewer answers than GitLab, which gets recommended in 90% of answers yet almost never leads. That gap between mention rate and first-pick rate tells you GitLab is treated as a credible alternative rather than a default. Bitbucket holds a distant third at a 56.8 score, and everything below it is essentially noise.

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: Replit (1.9), Jenkins (1.8), Fossil (1.8), Launchpad (1.8), Dependabot (1.7). 43 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.
