Onyx

Onyx, formerly Danswer, is a platform for searching and working with company knowledge. It indexes content from connected applications and provides a unified chat and search interface.

Connectors support Google Drive, Slack, Confluence, GitHub, and other services. Answers can cite documents, while custom agents can use dedicated instructions, knowledge, and actions.

The Community Edition can be self-hosted for free, alongside paid cloud offerings; Business starts at $20 per user per month billed annually. Setup requires infrastructure and model configuration, and syncing source permissions is an Enterprise feature that matters for sensitive content.
