Graphon
A Python graph execution engine for building and running agentic AI workflows, with queue-based orchestration, built-in workflow nodes and DSL import support.
Graphon is a Python graph execution engine for agentic AI workflows. It includes a working queue-based execution engine with event-driven orchestration, graph parsing and validation, a fluent graph-building API, shared runtime state and a variable pool.
It ships built-in node implementations for common workflow patterns, DSL import support with Slim-backed LLM nodes, and integration protocols for HTTP, file, tool and human-input steps. The engine's layers and external command channels are designed to be extensible, and a runnable end-to-end example is included alongside setup and architecture documentation.
It is released under the Apache-2.0 license.
