Jitsu
MIT-licensed event pipeline, no licence footnotes.

sovereigntyJitsu is the option with nothing to explain: MIT, self-hostable, real-time event collection into ClickHouse, BigQuery, Snowflake, Postgres and the rest. Around 4.8k stars. It is smaller than RudderStack and has fewer destinations, and that is the entire trade — you give up catalogue breadth and get a licence you can read in five minutes and never think about again. For a team whose legal review killed the last two candidates, that is often the deciding feature.
