When buyers ask AI engines about API gateway software, Kong consistently emerges as the leader, mentioned 37.5% of the time. Other notable names in this area include Tyk and AWS API Gateway. Kong's visibility in AI-driven inquiries speaks to its prominence in the infrastructure space.
The rankings are influenced by citations from sites like zuplo.com, digitalapi.ai, and mgsoftware.nl, which are frequently referenced. These domains often function as aggregators or review platforms, providing a broad overview and comparisons that shape AI recommendations based on authority and recent evaluations.
For buyers evaluating this list, AI engines prioritize brands with current reviews and third-party validation, emphasizing those with strong topical authority. Consider how these engines value aggregated insights and validations when choosing an API gateway solution, ensuring alignment with credible and recent analysis.
At a glance
What we observed in this category
Kong leads the API gateway software category with a visibility score of 37.5%, more than eight times the category average of 4.4%. This gap is material because it means Kong appears in AI-generated answers far more often than any peer, compounding brand recall over time. Kong also recorded a visibility delta of 12.5 points since the previous period, making it the only brand showing measurable upward movement. No brand recorded a visibility fall, suggesting the landscape below Kong is largely static.
A sharp divergence between visibility and citation rates runs through this category. Gravitee has zero visibility yet a 50% citation rate, the highest of any brand in the data. Tyk shows perfect parity at 25% each, while Kong's citation rate of 12.5% is far below its 37.5% visibility score. This means Kong is named often but not frequently linked as a source, whereas Gravitee is trusted as a reference document even though the AI rarely names it as a product recommendation.
Google AI Mode is the dominant engine across all 20 brands in this category, listed as the top engine for every ranked brand. Third-party sources anchor the AI's citations rather than vendor domains. Zuplo.com, digitalapi.ai, daily.dev, reddit.com, and moesif.com all appear in the top cited sources, alongside gravitee.io as the only vendor domain in that list. This pattern indicates the AI is drawing on independent review and community content rather than official product pages when constructing its answers.

How to read this 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 →
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 30 days and refresh this page automatically. How AI search ranking works →
