All tools on two or more CDPs →About these numbers
CdpHub documents each integration from the platform's own catalog, so a listing records what the platform says it supports, not a test of the connector. Each one notes which way data flows and where the integration runs. A platform can list more than one connector for Customer.io, so listings can outnumber platforms; a platform that both sends data to Customer.io and reads from it is counted once, as doing both. The rank orders all 2,243 tools in the directory by how many platforms list them; tools listed on the same number of platforms share a rank. Counts are updated as catalogs change; this page reflects the directory as of October 18, 2026. CdpHub is independent and not affiliated with Customer.io or any platform listed.
