Graflow - Stop wrestling graphs. Pythonic pipelines for LLM agents.

Graflow is an open-source Python orchestration engine for agentic workflows — the sweet spot between deterministic pipelines and fully autonomous agents. No graph complexity. Write Pythonic workflows and compose them with >> and |. Designed for developer experience. Build production-grade AI workflows that stay readable and easy to operate.
