Open Source Customer Data Platform
A customer data platform sees everything - every event, identity, and trait stitched into one profile - which is exactly why a few well-known "open" CDPs quietly relicensed to source-available once they had the traction. The pipeline that unifies your customer data is too consequential to depend on someone else's terms. The open source options here let you own the ingestion, identity resolution, and the profiles they produce outright.
