Agenta

Agenta is an open-source platform designed to help teams build, iterate, and operate robust LLM-powered applications. It provides an end-to-end workflow for designing prompts, comparing model variants, and managing application behavior across development and production environments. The primary purpose of Agenta is to make LLM app development more systematic, observable, and reliable rather than ad-hoc and trial-and-error.

The platform offers structured prompt engineering tools, including versioning, parameterization, and environment-aware configuration, so you can safely experiment with different prompts and models. It supports evaluation pipelines where you can define custom metrics, run A/B tests, and compare responses across models, prompts, or configurations. Agenta also includes debugging utilities such as detailed request/response inspection, trace logs, and error analysis to help identify failure modes in complex LLM workflows. In production, its monitoring features track quality, latency, and usage patterns, enabling continuous improvement and easier incident investigation.
