Promptulate

Promptulate is a Python framework for building large language model agent applications. It is developed by Cogit Lab and described as a lightweight AI native development framework, with the nickname pne. Its stated philosophy is to borrow ideas from other open source frameworks and lower the barrier to entry, so that most tasks can be completed in a few lines of code. The core idea is a single function, pne.chat, that wraps the essential capabilities and can replace direct use of the OpenAI SDK while adding extra features. The framework supports a wide range of models through litellm integration, and offers several agent types, including web, tool and code agents that plan, reason and act. Any Python function can be turned into a tool, tools from frameworks such as LangChain can be reused, and hooks and lifecycle management allow custom code at each stage of agents, tools and models. Further features include a terminal client for debugging prompts, prompt caching, and Streamlit components for quick prototyping. It is aimed at Python developers who want to build agent applications without learning a large framework. The documentation site provides a Quick Start guide, guides, use cases and a link to the GitHub repository. Promptulate is released under the Apache 2.0 license, and no paid plans are published.
