Onyx is a fully open-source AI platform that brings together chat, agentic RAG, deep research, and custom agents in a single self-hostable application. Unlike cloud-only alternatives, Onyx runs on Docker, Kubernetes, or any major cloud provider, giving teams complete control over their data and deployment. The platform connects to 50+ data sources via indexing connectors and supports every major LLM provider — from self-hosted Ollama models to OpenAI and Anthropic. Its hybrid search combines keyword and vector indexing, while multi-step research agents ranked top on their benchmark as of February 2026. Onyx ships in two editions: a Community Edition (MIT-licensed) covering chat, RAG, agents, and actions, and an Enterprise Edition adding SSO, RBAC, audit logs, and whitelabeling. With nearly 24k GitHub stars and 4k new this week, it's become the de facto open-source alternative to tools like Glean and Guru.
Reviewer scorecard
“The coding capabilities lag behind Claude and GPT. Real-time X data is interesting but not enough to make it a daily driver for development.”
“If you've been paying for Glean or Guru, Onyx is your escape hatch. Self-hosting is straightforward with Docker, and the 50+ connectors cover virtually every data source your team needs. The hybrid search quality is genuinely competitive.”
“The 'unfiltered' positioning is mostly marketing. It's less restricted on some topics but the underlying model quality doesn't match the top tier.”
“Self-hosting a full AI platform isn't actually free — you're paying in ops overhead, GPU costs, and the engineer-hours to maintain it. The enterprise features that actually matter (SSO, RBAC) are paywalled behind a license that isn't priced publicly, which is a red flag for budget planning.”
“Having real-time social data baked into an AI is unique. For trend analysis, market sentiment, and cultural pulse-checking, Grok fills a niche no one else does.”
“Onyx represents a critical counter-movement to AI centralization. As enterprise AI spending scrutiny intensifies, self-hostable alternatives with full data sovereignty will capture the compliance-sensitive markets that hyperscalers are locked out of.”
“For content teams that need AI over their own knowledge base without shipping documents to a third-party cloud, Onyx is a genuine solution. The voice mode and image generation are unexpected bonuses that make it a complete workspace.”
