Coze Loop

Coze Loop is a developer-oriented, open-source platform-level solution for AI agent development and operations, built by ByteDance/Coze. It provides full lifecycle management capabilities including prompt engineering with a visual Playground for real-time testing across multiple LLMs, systematic evaluation with automated multi-dimensional testing of prompts and agent outputs, and observability that records every stage from user input to AI output including prompt parsing, model invocation, and tool execution. With Docker Compose and Kubernetes Helm Chart deployment options, Coze Loop supports integration with OpenAI, Volcengine Ark, and other LLM models through the Eino framework. Features include prompt version management, evaluation set management, experiment management, and SDK trace reporting. The platform is designed for developers building production-grade AI agents who need debugging, evaluation, and monitoring tooling in one unified platform.
