Onyx
Open-source enterprise search and AI chat that connects company knowledge, custom agents, and controlled deployment options.
About Onyx
Onyx is an open-source enterprise search and AI assistant built around a natural-language interface for company documents, applications, and people. It combines internal search with access to major language models, custom agents, web search, deep research, code interpretation, image generation, and actions through MCP or OpenAPI. Persistent connectors synchronize changes from source systems. Permission inheritance and role-based access help keep results inside existing access boundaries. Teams willing to manage infrastructure can use the free, self-hosted open-source edition. The managed Business plan is $20 per user each month with annual billing, which makes seat count an important cost factor. Enterprise adds SSO, on-premise and region-specific deployment, custom integrations, data exports, dedicated support, and an SLA. Its price and final scope require a sales discussion. Onyx fits organizations that want broad knowledge access and deployment control in one platform, provided they accept either the operational work of self-hosting or the recurring cost of managed seats.
Best for
Best use cases
A support or operations team needs answers grounded in several connected knowledge bases without searching each system separately.
An engineering group wants to deploy AI inside its own network while preserving document permissions and access boundaries.
A company wants custom agents to combine internal knowledge with web search, deep research, code interpretation, or MCP actions.
Compare before choosing
The open-source edition lowers license cost but transfers hosting, upgrades, security operations, and capacity planning to the adopting team.
Business provides a managed package at $20 per user monthly on annual billing, which is simpler to operate but grows directly with seat count.
Enterprise adds SSO, private deployment choices, custom integrations, support, and an SLA, while pricing and final scope require a sales process.

Pros
- The self-hosted open-source edition removes software license cost and gives technical teams direct control over deployment.
- More than 40 connectors, major LLM access, agents, research tools, and APIs can consolidate several AI workflows in one interface.
- Enterprise options cover SSO, on-premise or regional deployment, custom integrations, dedicated support, and an SLA.
Cons
- Business costs $20 per user per month on annual billing, so larger rollouts can create a substantial recurring seat expense.
- Self-hosting shifts infrastructure, upgrades, security operations, and capacity management onto the adopting organization.
- Enterprise price and final deployment scope are not fixed upfront and require a sales conversation before budgeting is complete.
