Omni, an open-source workplace search and chat platform, launched today to challenge expensive proprietary solutions like Glean. Built entirely on Postgres using ParadeDB and pgvector, the project offers a self-hosted alternative for small to mid-size teams. The core innovation is its Postgres-only architecture, eliminating the need for Elasticsearch or dedicated vector databases. Developers can deploy Omni via a single `docker compose up` command, syncing data from Google Drive, Gmail, Slack, Confluence, Jira, and more.

Users connect their own LLM providers like OpenAI or Anthropic, enabling hybrid search combining full-text and semantic results within a chat interface. The platform respects existing permissions, keeping data on-prem and avoiding vendor lock-in. This approach significantly reduces operational complexity for organizations wary of cloud dependencies.
