When buyers inquire about Infrastructure as code tools, AI engines frequently point to Pulumi as the leader, citing it in 87.5% of responses. Pulumi is backed by a 25% visibility score. Other notable brands in this space are Pulumi ESC and OpenTofu, frequently mentioned alongside Pulumi for their capabilities and features.
The rankings are shaped by data predominantly drawn from highly referenced sources like youtube.com, pulumi.com, and firefly.ai. These platforms serve as aggregators or review sites, indicating that the AI engines are leveraging rich resources from well-trafficked sites to inform their guidance on infrastructure tools.
For buyers evaluating these tools, consider the emphasis that AI engines place on recent reviews and third-party validation. The dominance of informational resources from topical authorities like youtube.com and pulumi.com suggests these engines value content that is both up-to-date and sourced from recognized leaders in the field.
At a glance
What we observed in this category
Pulumi leads the Infrastructure as Code category with a composite score of 43.8, nearly 2.5 times higher than the next closest brand, Pulumi ESC at 26.2. This gap is significant because Pulumi rose from rank 11 to rank 1 in a single audit cycle, gaining 25 visibility points and 62.5 citation points simultaneously. Terraform, which previously held rank 1 with 75% visibility, has dropped to rank 4 with only 25% visibility, a 50-point decline, signalling a meaningful shift in how Google AI Mode is framing this category.
A notable divergence exists between being named and being cited. OpenTofu and Terraform both hold 25% visibility but have 0% citation rates, meaning AI surfaces them in answers but does not link to their domains. Conversely, Pulumi ESC carries 0% visibility yet an 87.5% citation rate, and Spacelift holds 0% visibility with a 50% citation rate. These patterns show that trusted source status in this category does not require consistent named mentions, and named presence does not guarantee citation.
Google AI Mode is the top engine for every brand in the dataset, confirming the audit is dominated by a single engine signal. The top cited sources include youtube.com, pulumi.com, firefly.ai, spacelift.io, and reddit.com, suggesting AI answers in this category anchor on community content and vendor documentation rather than analyst reports. The presence of encore.dev and cio.economictimes.indiatimes.com in the cited sources list indicates AI is also drawing from niche developer blogs and trade media.

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 →
