## What it is
CGraph is a cross-platform directed acyclic graph (DAG) execution framework written in pure C++11 with no third-party dependencies, also offering Python bindings (pycgraph). It lets users define nodes and dependency groups to schedule tasks with parallelism, conditionals, loops, pause/resume, and timeout control.

## Use cases
- run dependent tasks as a DAG pipeline
- execute independent tasks in parallel with dependency control
- build a workflow engine in C++ without third-party libraries
- schedule AI agent pipelines as a graph
- add pause, resume, and timeout handling to task graphs
- compare DAG scheduling performance against taskflow

## When to choose
- you need a dependency-free, header-friendly C++ DAG scheduler
- you want cross-platform support including Android
- you prefer Python APIs for building pipelines
- you need fine-grained control over conditional, loop, and concurrent graph execution

## When to avoid
- you need distributed multi-machine task orchestration
- you want a batteries-included workflow UI like Airflow
- your project already standardizes on another task framework such as taskflow

## Facets
- artifact type: framework
- maturity: active
- function: workflow-automation, concurrency, scheduling
- domain: developer-tools
- platform: cpp, python, windows, cross-platform
- tags: dag, pipeline, task-graph, parallel-computing, no-dependencies, pycgraph, automation, algorithms, linux, macos, android
