Where SaaS buyers compare most
Comparison demand by software category. Email marketing & CRM and website builders draw the most head-to-head research — the categories where switching costs bite and the choice actually changes the business.
Challengers out-pacing the incumbents
In these categories a newer entrant now shows up in more buyer comparisons than the established player it was built to unseat — a leading signal of a shifting market. HubSpot leads, appearing in 18 matchups vs Salesforce's 5.
Methodology
We took every published comparison in the software vertical on A Versus B as of June 14, 2026 — 424 head-to-head SaaS pages — and counted how many distinct comparisons each tool appears in. A tool matched against many rivals ranks higher because it sits at the center of a wider web of buyer research.
The tool leaderboard counts software products only; programming languages and frameworks are excluded. Category clusters are assigned by keyword-matching each comparison’s tools to our software subcategories (CRM, project management, AI tools, and so on). The “challengers” cut surfaces categories where a newer entrant appears in more comparisons than the incumbent it competes against. Data is refreshed daily from our live database.
