Use tool ↗About Onyx
Onyx is a chat and enterprise-search application that indexes 40+ work apps such as Slack, Confluence, Google Drive and GitHub, then lets people and custom agents query that knowledge through the LLM of their choice. Retrieval respects the access rights of the source system, and the whole stack can run in a private cloud, on bare metal or in an air-gapped network. It also adds web search, a code interpreter, image generation, MCP tools, a Slack bot and a Chrome extension. It started as the open-source project Danswer, and the Onyx team announced in September 2026 that it was joining Zoom.

Pros & cons of Onyx
Onyx fits teams that want a ChatGPT-style workspace over their own documents without sending the index to a vendor cloud. The free community edition covers chat, connectors and agents; SSO and role-based access sit behind the paid tiers. The Zoom deal is new, so check how the self-hosted and open-source promises are written into your contract.
Pros
- Permission-aware retrieval inherits access rules from each connected source
- Runs self-hosted, including air-gapped, with a free MIT-licensed community edition
- Works with many LLM providers, including local models
- Connects to 40+ apps and exposes agents, MCP tools and developer APIs
Cons
- SSO, role-based access and white-labeling require a paid or enterprise licence; the repository carries a separate enterprise licence for those directories
- Self-hosting a search index and connectors needs real infrastructure and upkeep
- Product roadmap now depends on a new parent company, and pricing for larger deployments is not published
Best for
- IT teams that must keep documents and embeddings inside their own network
- Companies that want one chat and search interface across Slack, Drive, Confluence and GitHub
- Teams that want to swap LLM providers without changing the interface
Not for
- Small teams that want a hosted assistant with zero setup or infrastructure work
- Buyers who need a vendor that is guaranteed to stay independent of a large platform company
Watch out: Onyx was announced as joining Zoom on September 23, 2026 (terms undisclosed). The founders say it stays open source and self-hostable, but long-term packaging and pricing may change.
