What is PocketFlow?
Building with large language models (LLMs) shouldn’t require a labyrinth of dependencies or complex configurations. Pocket Flow is a minimalist, 100-line framework designed to strip away the bloat while retaining the power you need. Whether you’re creating AI agents, workflows, or RAG systems, this framework keeps things lightweight and flexible—zero dependencies, zero vendor lock-in, and maximum control.
It’s not just about simplicity; it’s about enabling agentic coding, where AI tools like Cursor AI help you build faster and smarter. Think of it as your foundation for crafting custom LLM applications without the overhead.
