Decision summary

Sales, Engineering, Customer Support, and Operations teams

Answering complex workplace questions by searching across connected knowledge sources with multi-step reasoning and verified sub-answer synthesis.

Best for

  • Teams needing self-hosted AI knowledge search with data residency control
  • Enterprises requiring air-gapped or on-premises deployment
  • Organizations prioritizing agent security against prompt injection

Watch out for

  • Benchmark results are not independently verifiable; underlying documents cannot be shared
  • Microsoft Teams and Zendesk integrations are announced but not yet available
  • Self-hosting requires operational expertise for setup and maintenance

Overview

An enterprise AI assistant that connects documented knowledge across Slack, Google Drive, and Confluence, Onyx uses agentic retrieval-augmented generation (RAG) with multi-step reasoning to answer complex workplace questions. The platform is distributed as open-source software through GitHub and supports deployment on individual laptops, on-premises servers, or in the cloud.

Agent Search: Beyond Basic RAG

Agent Search is Onyx's flagship capability and what distinguishes it from simpler document-retrieval chatbots. Rather than fetching relevant chunks and generating a single-pass answer, Agent Search decomposes complex questions into narrower, well-defined sub-questions. Each sub-question flows through query expansion, targeted document search, result validation, reranking, subanswer generation, and answer verification. The system then synthesizes these verified sub-answers into a final response.

This architecture addresses a known limitation of basic RAG: when a question does not map neatly to existing document chunks, traditional systems struggle. Onyx's own example illustrates the difference—asked "How did we close this customer so quickly?", Agent Search does not merely search for documents mentioning the customer. It explores the sales process, compares it against typical sales cycles, investigates proof-of-concept processes, and synthesizes findings across multiple knowledge sources.

Security: Credential Injection Proxy

Onyx's security model takes a different approach from most AI agent platforms. Rather than storing real OAuth tokens or API keys in the agent's runtime environment—where prompt injection attacks can exfiltrate them—Onyx uses a credential injection proxy. Agents operate in network-isolated sandboxes holding only placeholder credentials (literally the string "replaced_by_egress_proxy"). Actual credentials are injected at the egress proxy boundary, meaning even if an attacker compromises the agent through prompt injection, the stolen tokens are worthless.

The vendor frames this design against OWASP's Top 10 for Agentic Applications and cites ISACA data showing 44% of organizations still authenticate agents with static API keys.

Integrations and Extensibility

Onyx integrates with Slack today, with Microsoft Teams and Zendesk support listed as forthcoming. The platform exposes a developer API with fine-grained API keys for programmatic access to its RAG, Agent, and Generative AI capabilities. Teams can create custom prompts, upload knowledge, and configure Actions that connect agents to external tools.

The platform targets four core enterprise personas: Sales, Engineering, Customer Support, and Operations. A 14-day free trial is available without requiring a credit card. Onyx has published internal benchmarking on workplace questions but acknowledges that the underlying documents cannot be shared publicly; a synthetic dataset modeled on enterprise document types is planned.

Score anatomy

The dimensions behind the editorial score, each with its judgment note. AI Readiness and GEO Score are platform assessments generated by VibeLaunch after submission.

Information quality

Vendor publishes benchmarking methodology and acknowledges its limitations, including non-shareable internal documents and a planned-but-unavailable synthetic dataset. Agent Search architecture is described in technical depth but lacks independent third-party evaluation of answer quality.

6.2
Verify

Onyx's benchmarking blog post details multi-step agentic RAG evaluation on workplace questions but explicitly states underlying documents cannot be shared publicly (official-developer_guide-03:p0266) and that a synthetic enterprise dataset is planned (official-developer_guide-03:p0267).

Ease of use

Slack integration and no-credit-card trial reduce initial friction. Self-hosting adds operational overhead for setup and configuration. Teams and Zendesk integrations are not yet available, limiting out-of-the-box utility for those ecosystems.

6.8
Verify

Slack integration is documented as currently available (official-developer_guide-02:p0009). Self-hosting requires GitHub-based updates and configuration (official-developer_guide-05:p0035). The 14-day trial requires no credit card (official-developer_guide-01:p0019).

Feature depth

Agent Search with sub-question decomposition, custom Actions, multi-source connectors, developer API, and LLM flexibility represent meaningful technical depth. Some integrations are still forthcoming, and the synthetic benchmark dataset is not yet available.

7.4
Contextual

Agent Search pipeline includes query expansion, validation, reranking, subanswer generation, and verification (official-developer_guide-04:p0034). Developer API covers messages, agents, LLMs, Actions, and auth (official-documentation-07:p0012). Custom prompts and Actions are configurable (official-developer_guide-01:p0012).

Workflow fit

Targets four core enterprise team personas with integrations into widely used workplace tools. The Slack connector is immediately useful, but Teams and Zendesk gaps reduce fit for organizations standardized on those platforms.

7.0
Contextual

Onyx targets Sales, Engineering, Customer Support, and Operations (official-developer_guide-01:p0034). Knowledge connectors span Slack, Google Drive, and Confluence (official-developer_guide-04:p0012). Slack integration is live; Teams and Zendesk are forthcoming (official-developer_guide-02:p0009).

Reliability

Self-hosted reliability depends on the operator's infrastructure and expertise. No published uptime SLA, third-party reliability audit, or production deployment case studies are available in the source pack. Benchmarking transparency is limited by non-shareable internal documents.

5.8
Verify

Self-hosting is distributed via GitHub (official-developer_guide-05:p0035). The benchmarking post acknowledges that internal documents and many answers cannot be shared (official-developer_guide-03:p0266). No SLA or third-party audit is cited in the source pack.

Value

No public pricing information is available beyond the 14-day trial. Open-source self-hosting may reduce licensing cost but adds operational overhead. Value assessment is speculative without pricing transparency. The free trial lowers evaluation risk but does not address long-term cost.

5.0
Verify

The 14-day free trial with no credit card is the only pricing information available in the source pack (official-developer_guide-01:p0019, official-documentation-07:p0024). No subscription tiers, per-seat pricing, or enterprise licensing details are documented.
