Kaeso vs OpenRouter

Side by side on what is actually measured: monthly searches for each name, the 3-month trend, and pricing. A cell is highlighted only where one tool is genuinely ahead.

Kaeso and OpenRouter compared on the figures this directory actually measures: pricing, category, and real monthly search demand for each name. Search demand is only shown where it has been measured. N/A means no figure yet, not zero. Kaeso is listed as open source; OpenRouter as freemium.

Search volume says how many people look for a tool by name, which is a reasonable proxy for how established it is. It says nothing about which one suits your work. The table below sets out what each is for, and each tool's own page covers its features, pricing tiers and the cases it handles badly.
