When AI engines are asked about Source code management platforms, GitHub consistently emerges as the leader, with a visibility percentage of 87.5%. Other notable brands mentioned include GitLab and Bitbucket. This visibility indicates that GitHub is frequently recognized in responses as a top choice for source code management.
The rankings reflect data mainly sourced from sites like devopsschool.com and 6sense.com. These are aggregator and review sites that compile user feedback and industry insights. Their frequent citation by AI engines shows their role in influencing which brands stand out and are preferred based on broader user opinions and expert evaluations.
For a buyer, the importance of recent reviews and third-party validation cannot be understated.

At a glance
What we observed in this category
GitHub leads the source code management category with 87.5% visibility, well above the 15.0% category average, and holds a composite score of 61.2. GitLab and Bitbucket both sit at 75.0% visibility but trail GitHub by 12.5 percentage points. Below those three, every other brand sits at 12.5% or zero visibility, creating a sharp cliff between the top three and the remaining 17 brands. That gap signals AI is treating this as a three-horse race with a dominant leader.
The visibility-to-citation divergence in this category is striking. GitHub holds the highest visibility at 87.5% yet records 0.0% citation, meaning the AI names it frequently but does not link back to it. GitLab at 75.0% visibility carries a 25.0% citation rate, making it the most-cited of the visible brands. Assembla sits at 0.0% visibility but still achieves a 25.0% citation rate, suggesting AI pulls it as a source reference even when not surfacing it as a recommended brand.
Every brand in the top 10 records Google AI Mode as its top engine, confirming the audit data is anchored entirely on that single engine. The cited sources in this category lean heavily on third-party review and comparison sites, including g2.com, reddit.com, thectoclub.com, and devopsschool.com. Aggregator and community sites appear more prominently than vendor-owned domains, which aligns with why brand citation rates remain low even for highly visible brands like GitHub and Bitbucket.

How to read this AEO ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
AEO rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 90 days and refresh this page automatically. How AI search ranking works →
