Agenta provides a complete open-source LLMOps solution that brings prompt engineering, evaluation, and observability together in one platform. Instead of storing prompts across scattered documents and communication channels, teams get a single source of truth for managing and versioning all prompt iterations. The platform includes a unified playground where users can compare prompts, models, and parameters side-by-side, making experimentation faster and more organized. Agenta supports automated evaluation pipelines that leverage LLM-as-a-judge, human reviewers, and custom evaluators to ensure changes actually improve performance. Its observability stack traces every request and highlights failure points, helping teams debug issues and convert problematic interactions into reusable test cases. Product managers, developers, and domain experts can collaborate through shared test sets, annotations, and interactive evaluations directly from the UI. Agenta integrates seamlessly with LangChain, LlamaIndex, OpenAI APIs, and any model provider, avoiding vendor lock-in. By consolidating collaboration, experimentation, testing, and monitoring, Agenta enables AI teams to move from chaotic workflows to streamlined, reliable LLM development.

CometLLM serves as a comprehensive platform for recording and visualizing your LLM prompts and chains. By utilizing CometLLM, you can discover effective prompting techniques, enhance your troubleshooting processes, and maintain consistent workflows. It allows you to log not only your prompts and responses but also includes details such as prompt templates, variables, timestamps, duration, and any necessary metadata. The user interface provides the capability to visualize both your prompts and their corresponding responses seamlessly. You can log chain executions with the desired level of detail, and similarly, visualize these executions through the interface. Moreover, when you work with OpenAI chat models, the tool automatically tracks your prompts for you. It also enables you to monitor and analyze user feedback effectively. The UI offers the feature to compare your prompts and chain executions through a diff view. Comet LLM Projects are specifically designed to aid in conducting insightful analyses of your logged prompt engineering processes. Each column in the project corresponds to a specific metadata attribute that has been recorded, meaning the default headers displayed can differ based on the particular project you are working on. Thus, CometLLM not only simplifies prompt management but also enhances your overall analytical capabilities.
