Onyx review
A broad enterprise search workspace with agents, research, analysis, and self-hosting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Onyx is an open-source AI platform for team chat, enterprise search, research, and custom agents. It is designed for teams that want to search connected company knowledge while also working with web research, uploaded documents, code, images, and spreadsheets. Developers, startups, and larger organizations can use hosted or self-hosted language models, with deployment options that include managed cloud environments, on-premises infrastructure, and air-gapped environments. Permission-aware connectors, document-level access controls, chat sharing, and usage analytics support collaborative business use.
The published plans show a freemium model with a free plan and a 14-day free trial. Business costs $20 per user per month with annual billing and includes a chat and search interface, access to all major language models, custom AI agents, web search, deep research, and image generation. Enterprise adds OIDC/SAML SSO, on-premise and region-specific deployments, custom integrations, dedicated support, and an enterprise SLA. The integration set covers Slack, Microsoft Teams, Zendesk, SharePoint, Confluence, Jira, Google Drive, Dropbox, Notion, Gmail, GitHub, Salesforce, and HubSpot, giving Onyx a wide connection surface for business knowledge.
Its standout strength is breadth within one workspace: custom agents can combine instructions, knowledge, and actions, while code execution and data analysis extend search into practical work. REST APIs and an MCP server also support programmatic access and broader platform integration. Onyx is a strong fit for teams that want search alongside research, automation, analysis, and control over deployment. It is less suitable for organizations seeking only a focused search interface or a narrowly scoped assistant, since its value depends on adopting several capabilities and, for enterprise governance requirements, moving beyond the basic plan.
