What is Onyx?

Onyx, formerly Danswer, indexes knowledge from tools such as Slack, Google Drive, Confluence, Jira and GitHub, together with their metadata and access permissions. People then ask questions in a chat interface and get answers grounded in documents they are allowed to see. It works with any model provider, adds web search, agents, skills and sandboxes, and can be deployed on your own infrastructure for data sovereignty. It offers 9 interface languages.

Good fit if

  • Your company knowledge is spread across many SaaS tools and you want one AI search over it.
  • Permissions matter: answers should only use documents a person can open.

Look elsewhere if

  • You want document chat for an individual or a small group: AnythingLLM.
  • You need a smaller deployment: the full compose stack runs about 14 services.

Before you adopt it

Onyx is MIT-licensed except the ee directories, which fall under a separate enterprise license for paid features. A Helm chart is included, and production setups use PostgreSQL, Redis, MinIO and a search index.
