openai-agents-js is the JavaScript/TypeScript version of the OpenAI Agents SDK, designed to give developers a lightweight but powerful framework for building agentic workflows, voice agents, and tool-augmented LLM systems in JS/TS environments. The SDK is provider-agnostic, meaning while it’s deeply compatible with OpenAI’s APIs, you can also adapt it to use other backends or extension layers. At its core, it introduces primitives like Agents, Tools, Guardrails, and Handoffs, letting you define structured multi-agent systems in a modular way. The repo includes examples showing how to build agents that call local functions, chain between agents, validate input/output, stream responses, and interact in real time (e.g. voice agents via WebRTC). It also has tracing and debugging support so you can introspect how agents executed their workflows. Because it aligns closely with the Python Agents SDK, it aims for cross-language parity so that JS/TS devs can adopt similar agent architectures.
Features
- JS/TS Agents SDK with primitives: Agent, Tool, Guardrail, Handoff
- Streaming / realtime responses and voice agent support via WebRTC or WebSockets
- Structured tool integration (wrap JS/TS functions as callable tools)
- Built-in tracing and debugging for visualizing agent execution paths
- Guardrails: input/output validation and safety constraints
- Cross-language alignment with the Python Agents SDK, enabling consistent agent patterns across stacks
