Why we publish this

Most hyperscaler agent-platform marketing only tells you their own number. Cross-platform mix-share is what investors / procurement / industry analysts actually need to evaluate the agent stack. We're the neutral indexer so we publish it freely, and the same data feeds the caller-attribution dashboard, the money flows page, and the paid Enterprise tier below.

The self-hosted (own domain) bucket is the most interesting line, it's the part of the agent web that's NOT locked into any one hyperscaler. That's structurally where our platform thrives.
