Overview
Onyx indexes content and permissions from 50+ apps into a hybrid vector and keyword index, then answers through agentic RAG, deep research and custom agents with web search, MCP actions and a code sandbox. It works with Ollama, LiteLLM, vLLM, Anthropic, OpenAI or Gemini, deploys via Docker, Kubernetes or Helm, and is reachable from the web app, Slack and Discord bots, an MCP server or a Chrome extension.
Who it is for: Teams wanting an internal search and chat layer over company apps
Strengths
- Lite mode runs the chat UI and agents in under 1 GB of memory
- Air-gappable: index, database and processing all run inside your environment
- MCP server gives Claude Code, Codex or any MCP client company context with user permissions
- Community Edition is MIT; install script sets up Docker in one command
Weaknesses
- SSO (OIDC, SAML), SCIM, RBAC, analytics and whitelabeling are Enterprise Edition only
- Standard mode adds index, worker, inference, Redis and MinIO containers
- Lite mode cannot index documents
- README gives no port or hardware figures for the Standard deployment
What it needs
- RAM ≥ 1 GB
- no GPU
- Compose
- Needs Redis (standard mode), MinIO (standard mode)
- Models: Ollama, LiteLLM, vLLM, Anthropic, OpenAI
