🚀 Deployment Modes

Onyx supports deployments in Docker, Kubernetes, Helm/Terraform and provides guides for major cloud providers. Detailed deployment guides found here.

Onyx supports two separate deployment options: standard and lite.

Onyx Lite

The Lite mode can be thought of as a lightweight Chat UI. It requires less resources (under 1GB memory) and runs a less complex stack. It is great for users who want to test out Onyx quickly or for teams who are only interested in the Chat UI and Agents functionalities.

Standard Onyx

The complete feature set of Onyx which is recommended for serious users and larger teams. Additional components not included in Lite mode:

• Vector + Keyword index for RAG.
• Background containers to run job queues and workers for syncing knowledge from connectors.
• AI model inference servers to run deep learning models used during indexing and inference.
• Performance optimizations for large scale use via in memory cache (Redis) and blob store (MinIO).
