How these numbers are measured

What is measured

Real agent actions running through Composio. One action is one request to an app, from a sample of recorded traffic.

How figures are published

Shares and category growth are shown as bands. The fastest-growing apps show their measured growth percentages.

What this does not establish

A high rank means agents used that app a lot, not that it's better. An app also has to have been used the week before to rank, so a one-week spike doesn't count.
