What is BrainyFlow?

A radically minimalist AI framework (just 300 lines! 🤯) Build Powerful AI Agents with Minimal Code, Maximum Freedom. _{Let Agents build Agents with Zero bloat, dependencies, or vendor lock-in 😮}

BrainyFlow is a framework enabling Agentic Coding through powerful abstractions.

It provides a simple interface for building complex AI applications based on nested directed graphs with shared state. It enables both humans and AI assistants to collaborate effectively on designing and implementing AI systems.

Features

• Brain-Easy 🧠: Intuitive for both humans and AI assistants

• Minimalist Design ✨: Core abstractions in just (you heard it right!) 300 lines of code

• Freedom 🔓: Zero bloat, dependencies, or vendor lock-in

• Composable 🧩: Build complex systems from simple, reusable components

• Powerful 🦾: Supports everything you love—(Multi-)Agents, Workflow, RAG, and more
• Agentic-Coding 🤖: Designed for AI-assisted development

• Universal 🌈: Works with any LLM provider or API

• Polyglot 🌍: Python and Typescript are both supported

Why Brainy Flow?

Current LLM frameworks are bloated... You actually only need 300 lines for a robust LLM Framework!

How does BrainyFlow work?

The single file in Python or Typescript capture the core abstraction of LLM frameworks: Graph!

• Node handles simple (LLM) tasks with a clear lifecycle (prep → exec → post).
• Flow connects nodes through Actions (labeled edges), orchestrating execution.
• Memory manages shared (global) and isolated (local) state, enabling communication between nodes.

From there, it's easy to implement all popular design patterns:

• Agent autonomously makes decisions based on context.
• Workflow chains multiple tasks into sequential pipelines.
• RAG integrates data retrieval with generation.
• Map Reduce splits data tasks into Map and Reduce steps.
• Structured Output formats outputs consistently.
• Multi-Agents coordinate multiple agents.
