Best open-source Customer data platforms
The best self-hosted CDP split in the c17.io catalog is Jitsu for an MIT Segment-shaped ingest (the published Segment / RudderStack Cloud / mParticle stack), PostHog when the job is product analytics and replay rather than a warehouse pipeline, Swetrix when the job is cookieless pageviews rather than a CDP, and RudderStack when you accept Elastic License 2.0 (not OSI — rudder-server forbids offering a substantial hosted set of its features). This is not Segment Unify or mParticle's every audience SKU.

FAQ
- Jitsu or RudderStack?
- Jitsu if you want the published MIT path. RudderStack Cloud is hosted; rudder-server is ELv2 — /compare/jitsu-vs-rudderstack.
- Segment or mParticle?
- Same published ingest — /replace/segment and /replace/mparticle.
- Is this Mixpanel?
- Pageviews stay on /replace/mixpanel (Swetrix). Product analytics stay on /replace/amplitude (PostHog). This page is the pipeline.
- Are these free?
- Jitsu is MIT. You pay hosting. RudderStack Cloud is hosted SaaS; the public server is ELv2. Template users never pay c17.
- How do I deploy it?
- Open /stacks/jitsu-cdp. Point the existing analytics snippet at it. Keep one destination working.
