// how it works

How it works

  1. Clarify your agent quality problem

    Identify what you need to improve — prompt quality, evaluation coverage, or visibility into failed runs.

  2. Deploy Coze Loop

    Clone the repo and prepare the Docker Compose deployment under release/deployment.

  3. Configure a model

    Edit model_config.yaml with your model provider's API key and endpoint/model ID.

  4. Start and open the UI

    Bring the services up and open the web interface to develop prompts, run evaluations and inspect traces.

Why people love it

Prompt development playground

Write, debug, optimize and version prompts in a visual playground with real-time interactive testing and side-by-side comparison.

Systematic evaluation

Automated multi-dimensional evaluation of prompts and agent outputs — accuracy, conciseness, compliance and more.

End-to-end observability

Records the full execution process from user input to AI output, including prompt parsing, model invocation and tool execution, capturing intermediate results.

Full lifecycle in one platform

Development, debugging, evaluation and monitoring live together instead of in separate tools.

Flexible deployment

Runs via Docker Compose for a quick local deployment or via a published Helm chart on Kubernetes.

Built on Eino

LLM integration is provided by the CloudWeGo Eino framework team, with a Go backend.

    Clone Coze Loop and enter the project directory.

    git clone https://github.com/coze-dev/coze-loop.git
    cd coze-loop
  2. Configure your model

    Edit the Docker Compose model config with your provider's API key and model/endpoint ID.

    # Edit release/deployment/docker-compose/conf/model_config.yaml — set api_key and model
  3. Start the service

    Bring Coze Loop up with the provided make target and open the UI.

    make compose-up

Questions, answered

Who maintains Coze Loop?

Coze Loop is maintained by coze-dev, the team behind Coze, with the Eino framework providing LLM integration.

Is Coze Loop free?

The open-source version is Apache-2.0 licensed and free to self-host; Coze also offers hosted products separately.

Does it need a paid API key?

Yes — you configure a model provider (the examples use Volcengine Ark / BytePlus ModelArk) with your own API key in model_config.yaml.

How does it compare to Langfuse or LangSmith?

Those focus mainly on tracing and evaluation; Coze Loop covers the full lifecycle including a prompt development playground and version management, in a self-hostable Go platform.

How do I get started?

Clone the repo, set your model in model_config.yaml, run make compose-up, and open http://localhost:8082.
