# Jitsu

> Jitsu is an open-source data integration platform and a self-hostable alternative to Segment. It collects event data from web, app, and server sources and streams it in real time into your data warehouse, with identity stitching, serverless functions, and Segment-compatible ingestion APIs.

## Comparisons

Each page below is also available as markdown by appending `.md` to its URL.

- [Compare Jitsu](https://jitsu.com/compare): Head-to-head comparisons of Jitsu against Segment, RudderStack, Snowplow, PostHog and Hightouch. Published prices, named concessions, no ticks and crosses.
- [Jitsu vs Segment](https://jitsu.com/compare/jitsu-vs-segment): Per active event against per tracked user. At 50,000 tracked users and 5M events, $219 against $575, both published rates.
- [Jitsu vs RudderStack](https://jitsu.com/compare/jitsu-vs-rudderstack): Same billing model. MIT against Elastic License 2.0, and at 5 million events $219 against $995, both published.
- [Jitsu vs Snowplow](https://jitsu.com/compare/jitsu-vs-snowplow): Snowplow requires schemas, a pipeline in your own cloud and a separate warehouse before the first event. Jitsu includes the database.
- [Jitsu vs PostHog](https://jitsu.com/compare/jitsu-vs-posthog): PostHog is a destination, Jitsu is the pipe. PostHog's analytics free tier is 1M events against Jitsu's 200,000; their data pipelines allowance is 10K events plus 1M rows.
- [Jitsu vs Hightouch](https://jitsu.com/compare/jitsu-vs-hightouch): Hightouch added event collection in 2024. One module of a closed sales-led platform, against an MIT-licensed pipe at a published price.
- [Self-hosted vs managed CDP](https://jitsu.com/compare/self-hosted-vs-managed-cdp): What running the pipeline yourself actually costs against paying somebody to run it.
