Jitsu

Jitsu is an open-source customer data platform and event pipeline for collecting, processing, and delivering event data from websites, applications, and servers to data warehouses and downstream tools. It is designed for data and engineering teams that want a lightweight alternative to traditional CDPs, with the option to run Jitsu in the cloud, in a private cloud, or on their own infrastructure. Jitsu was part of Y Combinator's Summer 2020 batch and the project has over 5,000 stars on GitHub.
