Decide what you want to achieve with onyx and check the README on GitHub for requirements before installing.
Clone the repository from GitHub (or take the packaged install route in step 3 if the README offers one).
Follow the project's documented install commands — the Run section below lists the exact ones — and add any required API keys or models.
Work through the README's quickstart example end to end, then adapt it to your own project or data.
Bring OpenAI, Anthropic, open models and more — the chat UI is model-agnostic.
Background workers sync knowledge from your apps and documents into a vector + keyword index for grounded answers.
Standard mode is the full platform; Lite mode runs the chat UI in under 1GB of memory for quick trials.
Official guides cover Docker, Kubernetes, Helm/Terraform and major cloud providers.
Beyond chat, Onyx provides agents and deep enterprise search across connected sources.
The README states Onyx Community Edition is free under the MIT license and covers the core RAG and AI chat features.

Yes — the code is open source under the MIT license. You can use, modify and redistribute it under that license's terms.
Onyx itself is free (CE under MIT); you bring your own LLM API key for chat, or run local models — embedding/indexing components run inside your deployment.
Those are polished paid SaaS products; Onyx is the open-source, self-hosted route — more ops work, but your data and model choice stay under your control.
Clone the repository from GitHub, follow the install commands in the Run section (taken from the project's README), and complete the documented quickstart example before adapting it to your own use case.
