Onyx

Onyx is an open-source enterprise search platform designed to help organizations unify access to information scattered across different apps, documents, and data sources. By connecting to a company’s internal systems such as drives, Slack, GitHub, Confluence, and more, Onyx enables teams to search all their content in one go, returning relevant results with enforced permissions and contextual understanding. This reduces the time spent tracking down critical information and improves the quality of answers for both human users and AI agents.

The platform offers flexible deployment options: companies can self-host Onyx in their own cloud, on bare metal, or even in air-gapped environments, ensuring that sensitive data remains within the organization’s control. All indexing, embedding, and model traffic stay inside the secure perimeter, satisfying stringent compliance requirements and giving IT teams confidence.

Onyx’s search pipeline optimizes for both speed and cost, with a token-efficient approach when working alongside large language models (LLMs). It supports integration with various LLMs and offers more than 40 app connectors, Actions (MCP/OpenAPI), and the ability to deploy custom AI agents. Granular permission controls, RBAC, and single sign-on support allow it to fit enterprise security frameworks. As open-source software, Onyx’s codebase is publicly auditable, promoting transparency for IT and security teams.

Teams across industries use Onyx as the backbone for their internal knowledge search, assisting both human employees and automated agents in making informed decisions based on company data. With benchmarks showing industry-leading retrieval quality, Onyx is suitable for organizations requiring precise, timely, and secure search across complex internal ecosystems.

Onyx is designed for IT leaders, operations managers, and technical teams within medium to large organizations who are responsible for managing information access and data security.

It’s particularly suited for enterprises with strict compliance needs or distributed internal data systems, where employees waste time searching across multiple siloed apps and platforms. Onyx helps centralize and streamline search, making it easier for staff to find critical documents, technical data, chat logs, and knowledge resources securely and efficiently.

This tool is ideal for industries such as finance, aerospace, defense, higher education, and any company operating at scale with strict data control requirements. It also appeals to organizations looking to deploy advanced AI capabilities and self-hosted retrieval-augmented generation (RAG) systems within their own infrastructure.
