What is Prax

Prax is an open-source development framework that allows users to create, manage, and deploy applications that use large language models (LLMs). It provides a visual interface for building logic-based workflows by connecting modular nodes. Each node performs a specific task such as sending a prompt to an LLM, calling an API, storing memory, or transforming data.

Unlike traditional programming frameworks, Prax enables developers to visually chain together these logic blocks to build intelligent systems without manually writing boilerplate logic for context handling, data routing, or API chaining.

Prax supports local development, self-hosting, and production deployment in both containerized and cloud environments. It is designed for developers, researchers, and teams who need to rapidly build and iterate on AI-powered systems.
