Documentation

# Onyx

## First-boot

Visit the public URL — the first registered user becomes the Curator (admin). No default password.

## Connect a data source

**Admin → Connectors → + Add Connector** — pick from:

- **Communication**: Slack, Discord, Microsoft Teams, Mattermost
- **Docs**: Confluence, Notion, Google Drive, SharePoint, Dropbox
- **Code**: GitHub, GitLab, Bitbucket
- **Tickets**: Jira, Linear, Zendesk
- **Sales**: Salesforce, HubSpot, Productboard
- **Web**: Web crawl, sitemap, single URL
- **Files**: Upload PDF / DOCX / MD / TXT

Each connector inherits ACLs from the source — a Slack message visible only to #eng-private stays visible only to people in #eng-private when retrieved.

## Chat with your knowledge

Default Assistant chats across ALL connected sources. Create role-specific Assistants under **Admin → Assistants** (e.g. 'Sales Assistant' scoped to Salesforce + product wiki only).

## LLM provider

Onyx supports OpenAI / Anthropic / Bedrock / Vertex / Azure / Ollama / local. Configure under **Admin → LLM**.

## Storage

Postgres (metadata, user data, ACLs) + Vespa (vector + lexical index) bundled in the all-in-one image. All persistent state at `/data`. 50 GB volume.

## Heavy app warning

Onyx is resource-intensive — 8 GB RAM minimum, 4 vCPU minimum. The all-in-one bundles Postgres + Vespa + indexer worker + web server + model server. Indexing large knowledge bases (10k+ docs) will saturate CPU for hours.
