Omni

Glean is charging mid-market companies a fortune just to search their own data, and Omni just showed up with the open-source alternative that small teams can actually self-host without the enterprise price tag. Built on Postgres and pgvector with ParadeDB — fewer dependencies, easier ops, and honestly a vector search setup that makes real sense for this use case. Connects to Drive, Slack, and Confluence out of the box, which means you are not rebuilding workflows to make search happen. It's fully open-source on GitHub, so your data team is not locked into yet another SaaS vendor with renewal negotiation headaches.
