Jitsu vs. Retention Science

Jitsu is an open-source customer data platform that collects events from websites, mobile apps and servers and delivers them to data warehouses, analytics tools and marketing destinations in real time. It is MIT-licensed and can be self-hosted, run as a managed cloud service, or deployed as a dedicated single-tenant private cloud. Jitsu's JavaScript integration is fully compatible with the Segment API, so existing analytics.js tracking calls work against Jitsu without any frontend code changes, and teams can run Jitsu alongside their current pipeline before committing to a migration.
