Site & App Search

What 7 leading Site & App Search apps are built on: the providers each one ships in its code or lists as an integration, grouped by layer and capability, and joined to the catalog.

7 reference apps 97 providers 85 observed in code 12 declared only 97.9% in the catalog 43.9 mean Kin Score 40 with a verified MCP server
How to read this. observed the integration ships in the app (SDK in a dependency file, source code, or an Android build analysis). declared the app names the integration itself (README, integrations page, store listing). Every row links the source it was read from. Providers not yet in the catalog are marked queued for profiling. Blueprint by API Evangelist, CC BY-NC-SA 4.0. Capabilities marked Turbo EA come from Turbo EA Capabilities by Vincent Verdet, CC BY 4.0 (notice); those marked API Evangelist extension are CC BY-NC-SA 4.0.
