Recently Updated

Who should use this?

Organizations with fragmented internal knowledge and Teams requiring permission-aware search.

Who should avoid it?

Teams without a connector and security owner, High-stakes answers without source review

What problem does it solve?

Onyx connects workplace repositories to cited search, chat, and agents with source permissions, but connector coverage, ACL fidelity, retrieval quality, and deployment ownership need a controlled pilot.

Would I recommend it?

Onyx earns a shortlist for technically owned, permission-sensitive knowledge search. Pilot one bounded department first and make ACL fidelity, evidence quality, and recovery—not demo fluency—the acceptance gates.

Direct verdict

Onyx earns a shortlist for technically owned, permission-sensitive knowledge search. Pilot one bounded department first and make ACL fidelity, evidence quality, and recovery—not demo fluency—the acceptance gates.

What to verify

Create a synthetic corpus across three repositories with conflicting versions, revoked users, nested groups, sensitive decoys, and known answers. Run 100 queries and record recall, citation accuracy, stale-source selection, forbidden retrieval, ACL update latency, connector failure behavior, deletion, model data paths, and operator hours.

Pricing

Freemium

Onyx publishes its core enterprise-search project for self-hosting, while managed and enterprise packaging is sales-led rather than represented by a stable public dollar table. Self-hosters still pay for infrastructure, models, storage, connectors, monitoring, upgrades, and support. Confirm current commercial terms before purchase. Reviewed September 1, 2026.

Free plan: Yes. The open-source edition can be self-hosted, subject to its current license and the buyer's infrastructure and model costs.

Pros

  • Open-source deployment path
  • Broad workplace connector coverage
  • Permission-aware retrieval design

Cons

FAQs

Is Onyx AI open source?

Yes. Onyx publishes a self-hosted open-source edition; commercial managed and enterprise services are separate.

Does Onyx preserve document permissions?

Onyx says it syncs source ACLs and document permissions. Buyers should test revocation and group-change latency against their own connectors.

How much does Onyx cost?

A stable public managed-service price table was not available in the reviewed official material. Self-hosting has infrastructure and model costs; enterprise terms require confirmation.

Can Onyx run with private models?

Its self-hosted and enterprise materials support buyer-controlled deployment and model choices, but every configured provider must be mapped.
