Pocket Flow – An open-source, lightweight AI application development framework that can be implemented with just 100 lines of code

What is Pocket Flow？

Pocket Flow is a minimalist framework for building LLM (Large Language Model) applications, implemented in just 100 lines of code. It is lightweight, dependency-free, and vendor-neutral, making it ideal for developers who want a simple and flexible way to build LLM-based applications. Pocket Flow supports powerful features such as multi-agent collaboration, workflow management, and Retrieval-Augmented Generation (RAG). It follows the Agentic Coding paradigm, where AI agents assist in development tasks, significantly boosting productivity.

Pocket Flow is well-suited for developers seeking to create LLM applications with maximum simplicity and efficiency.

Key Features of Pocket Flow

Multi-Agent Support: Allows the creation and coordination of multiple agents, each assigned to specific tasks like search, conversation, or data processing.
Workflow Management: Enables the design of complex workflows, combining tasks in sequence or based on conditions for automation.
Retrieval-Augmented Generation (RAG): Enhances generated content by integrating relevant retrieved data, improving accuracy and relevance.
Lightweight Development: Implemented in only 100 lines of code, free from redundant dependencies—ideal for fast development and deployment.
Agentic Coding: Supports the Agentic Coding paradigm where AI agents assist in coding tasks to increase development speed.
Multi-language Support: Available in various programming languages including Python, TypeScript, Java, C++, and Go, catering to diverse developer needs.

Technical Foundations of Pocket Flow

Core Graph Abstraction: Pocket Flow is built around a graph-based abstraction, where nodes represent tasks and edges define their relationships and execution order. This structure enables a clean and intuitive implementation of complex workflows and multi-agent collaboration.
Minimalist Codebase: By trimming unnecessary dependencies and non-essential features, Pocket Flow keeps only the core functionalities necessary for an LLM framework. This results in a lightweight, fast-loading, and developer-friendly toolkit.
Agent Collaboration: Supports multiple agents that can either operate independently or interact through message passing or shared state.
Dependency-Free & Vendor-Lock-Free: Avoids reliance on third-party libraries or platforms, giving developers full freedom to extend, customize, and deploy the framework without vendor constraints.
