openai-agents-js vs adk-rust
JavaScript and Rust frameworks for building AI agents
openai-agents-js and adk-rust both support agent orchestration, tools, and realtime voice workflows. openai-agents-js targets JavaScript and TypeScript applications, while adk-rust offers a modular Rust framework with broad model-provider and deployment options.
openai-agents-js: Build Multi-Agent and Voice Workflows
A TypeScript SDK for building LLM agents that use tools, delegate work, and manage conversations. It also supports sandboxed tasks and low-latency voice agents, making it useful for teams building more than a single prompt-and-response flow.
adk-rust: Build AI Agents in Rust
ADK-Rust is an async, model-agnostic framework for building and running AI agents in Rust. It combines agent orchestration with tools, memory, graph workflows, servers, and realtime voice capabilities.

Key differences
- openai-agents-js is written in TypeScript and requires Node.js 22 or later for its documented Node.js environment; adk-rust is written in Rust and requires Rust 1.95 or newer.
- openai-agents-js emphasizes agent handoffs, guardrails, sessions, tracing, sandboxed tasks, and browser-based realtime voice; adk-rust also includes graph workflows with checkpoints, durable runs, HTTP serving, memory, and governance features.
- adk-rust connects to providers including Google Gemini, OpenAI, Anthropic, Ollama, and mistral.rs; openai-agents-js supports OpenAI APIs and other providers.
- openai-agents-js is licensed under MIT; no license information is included for adk-rust.
- openai-agents-js has 3.9k stars and 987 forks, compared with 717 stars and 111 forks for adk-rust.
- adk-rust requires checking version compatibility because its 3.0.0 release candidate is unpublished and includes breaking API changes; its latest published release is 2.3.0.
Choose openai-agents-js if you…
- build agent features in a JavaScript or TypeScript application.
- need agent handoffs, conversation history, guardrails, or tracing.
- want browser-based realtime voice or sandboxed tasks in the same SDK.
Choose adk-rust if you…
- want a Rust-based, async framework with typed tools.
- need to choose among multiple model providers or use local inference.
- need graph checkpoints, durable runs, HTTP serving, or governance features such as approvals and audit records.
