What is PromptMage?
PromptMage is a Python framework designed to simplify the development of complex, multi-step applications based on large language models (LLMs). It offers an intuitive self-hosted interface that supports prompt testing, comparison, version control, and collaboration, making it suitable for teams ranging from small groups to large enterprises. Its goal is to enhance the efficiency of LLM workflow management and accelerate real-world deployment. The framework emphasizes engineering best practices: treating prompts as first-class citizens, featuring built-in FastAPI-generated APIs, supporting both manual and automated prompt evaluation, and enabling automatic reasoning and validation through type hints. Currently in alpha, its APIs and features may change at any time.
