Onyx AI | Open Source Enterprise Search & AI Assistant | WarmIndex

Onyx is an open-source, self-hostable AI chat platform that enables teams to interact with any LLM while integrating enterprise search, custom agents, and company data sources for efficient knowledge retrieval and AI-assisted workflows.

🚀 Overview

Onyx is a feature-rich, open-source AI platform designed as a unified interface for generative AI in the workplace. It connects to any large language model (LLM) like OpenAI, Anthropic, or local models via Ollama, and integrates with over 40 knowledge sources such as Google Drive, Slack, databases, and more. This allows teams to chat naturally, search internal documents, browse the web, run code, generate images, and build custom AI agents—all in a secure, self-hosted environment.

The project solves the problem of scattered company knowledge and inefficient information retrieval by providing enterprise-grade RAG (Retrieval-Augmented Generation), hybrid search with knowledge graphs, and agentic tools that reduce hallucinations and deliver reliable responses from internal data. It's built for developers, teams, and enterprises who need data sovereignty, air-gapped deployment, and scalability without relying on proprietary SaaS like ChatGPT Enterprise or Glean.

Onyx was created to offer a flexible, open-source alternative that gives full control over data, infrastructure, and customization, empowering organizations to leverage AI privately and cost-effectively.
