Pocket Flow is a [100-line](https://github.com/The-Pocket/PocketFlow/blob/main/pocketflow/__init__.py) minimalist LLM framework
- **Lightweight**: Just 100 lines. Zero bloat, zero dependencies, zero vendor lock-in.
- **Expressive**: Everything you love—([Multi-](https://the-pocket.github.io/PocketFlow/design_pattern/multi_agent.html))[Agents](https://the-pocket.github.io/PocketFlow/design_pattern/agent.html), [Workflow](https://the-pocket.github.io/PocketFlow/design_pattern/workflow.html), [RAG](https://the-pocket.github.io/PocketFlow/design_pattern/rag.html), and more.
- **[Agentic Coding](https://zacharyhuang.substack.com/p/agentic-coding-the-most-fun-way-to)**: Let AI Agents (e.g., Cursor AI) build Agents—10x productivity boost!
Get started with Pocket Flow:
- To install, ```pip install pocketflow```or just copy the [source code](https://github.com/The-Pocket/PocketFlow/blob/main/pocketflow/__init__.py) (only 100 lines).
- To learn more, check out the [documentation](https://the-pocket.github.io/PocketFlow/). To learn the motivation, read the [story](https://zacharyhuang.substack.com/p/i-built-an-llm-framework-in-just).

- 🎉 Join our [Discord](https://discord.gg/hUHHE9Sa6T) to connect with other developers building with Pocket Flow!
- 🎉 Pocket Flow is initially Python, but we now have [Typescript](https://github.com/The-Pocket/PocketFlow-Typescript), [Java](https://github.com/The-Pocket/PocketFlow-Java), [C++](https://github.com/The-Pocket/PocketFlow-CPP) and [Go](https://github.com/The-Pocket/PocketFlow-Go) versions!
## Why Pocket Flow?
Current LLM frameworks are bloated... You only need 100 lines for LLM Framework!

## How does Pocket Flow work?
The [100 lines](https://github.com/The-Pocket/PocketFlow/blob/main/pocketflow/__init__.py) capture the core abstraction of LLM frameworks: Graph!

From there, it's easy to implement popular design patterns like ([Multi-](https://the-pocket.github.io/PocketFlow/design_pattern/multi_agent.html))[Agents](https://the-pocket.github.io/PocketFlow/design_pattern/agent.html), [Workflow](https://the-pocket.github.io/PocketFlow/design_pattern/workflow.html), [RAG](https://the-pocket.github.io/PocketFlow/design_pattern/rag.html), etc.
