What is Agent Nexus?
Agent Nexus is an open-source AI agent orchestration platform that lets developers build, deploy, and monitor multi-agent systems on their own infrastructure. It is model-agnostic, working with Anthropic Claude, OpenAI GPT, Google Gemini, and local Ollama models, so teams keep full data sovereignty and avoid vendor lock-in. The agent builder lets you configure each agent's system prompt, model, temperature, and max tokens, while a live playground streams the agent's reasoning in real time through an SSE trace panel and saves every session to a replayable conversation history. For more complex automations, a visual canvas editor built on React Flow provides drag-and-drop workflow construction, and webhook triggers expose persistent inbound HTTP endpoints that fire an agent or workflow run on demand. Governance features include risk-based approval gates that pause any tool marked requires_approval until a human approves, full run traces logging memory retrieval, context retrieval, model calls, and tool calls, isolated multi-workspace support, and role-based access control across owner, admin, member, and viewer roles. It is aimed at engineering teams, enterprises needing self-hosting and observability, and anyone building production multi-agent applications. The project is MIT-licensed and distributed for self-hosting.
What is Agent Nexus used for?
Building multi-agent AI systems, orchestrating agent workflows visually, self-hosting AI agents for data sovereignty, running model-agnostic agents across Claude/GPT/Gemini/Ollama, adding human approval gates to agent runs, monitoring agent runs with full trace logs

Questions about Agent Nexus
What is Agent Nexus?
Agent Nexus is an open-source, self-hosted AI agent orchestration platform for building, deploying, and monitoring multi-agent systems. It is model-agnostic, supporting Anthropic Claude, OpenAI GPT, Google Gemini, and local Ollama models.
Is Agent Nexus free?
Yes. Agent Nexus is MIT-licensed open-source software that you self-host, so there are no license fees or paid tiers; you only pay for the infrastructure and model API usage you run it on.
Which AI models does Agent Nexus support?
Agent Nexus is model-agnostic and supports Anthropic Claude, OpenAI GPT, Google Gemini, and local Ollama models, letting teams switch providers or run models locally without vendor lock-in.
Agent Nexus vs LangGraph?
Both orchestrate multi-agent workflows, but Agent Nexus ships as a self-hosted platform with a visual React Flow canvas, a live playground, role-based access control, and human approval gates out of the box, whereas LangGraph is a code-first library you embed in your own application.
