8.4/10 is the mean of the 5 criteria that apply. Scored on the five-criteria rubric v1, 29 September 2026. How scoring works
Pricing
- MIT licence
- Model API costs from providers still apply
Key Features
- Multi-agent workflows with guardrails on inputs and outputs
- Built-in tracing for debugging runs
- Sandbox agents with local Unix and Docker, plus filesystem, shell, memory and skills
- Realtime voice agents and voice pipelines
- Works with OpenAI APIs and 100+ other LLMs
Pros & Cons
Pros
- MIT licensed and free to use
- Installs with one pip command on Python 3.10+
- Provider-agnostic, per the docs
- Human-in-the-loop and tracing are built in
Cons
- Python only
- You still pay model providers
- Sandbox and long-horizon features add setup
- Some features lean on OpenAI models
The OpenAI Agents SDK is a strong pick for Python developers building multi-agent apps who want light abstractions and built-in tracing. Teams on other languages or who want a visual builder should look at LangGraph or Langflow. Highly recommended for its niche.
