Pocket Flow - LLM Framework in 100 Lines
A 100-line minimalist LLM framework for (Multi-)Agents, Workflow, RAG, etc.
-
Install via
pip install pocketflow, or just copy the source code (only 100 lines). -

Why Pocket Flow?
Pocket Flow lets you build LLM apps just by chatting with agents like Cursor AI—no need for low-level coding.
Pocket Flow is designed for LLM Agents. If you’re using Cursor AI...
- 🫠 With LangChain-like frameworks: Cursor AI gets overwhelmed by complex abstractions and calls deprecated functions by mistake.
- 😐 With No Framework: Cursor AI writes functional but lacks modularity and maintainability.
- 🥰 With Pocket Flow: (1) Minimal and expressive—easy for Cursor AI. (2) Nodes and flows keep the codes modular and maintainable. (3) The shared store separates data from compute logic.
With just 100 lines, Pocket Flow ensures Cursor AI follows good coding practices without sacrificing flexibility.
To set up:
-
Cursor Rules: Copy .cursorrules into your project’s root.
-
ChatGPT & Claude: Create a project (ChatGPT andClaude) and upload the docs folder to project knowledge.
What Is Pocket Flow?
The 100 lines capture what we believe to be the core abstraction of LLM projects:
- Computation: A graph that breaks down tasks into nodes, with branching, looping, and nesting.
- Communication: A shared store that all nodes can read and write to.
From there, it’s easy to implement popular design patterns like (Multi-)Agents, Workflow, RAG, etc.
