## What it is
imnodes is a small, dependency-free node editor extension for dear imgui, written in C++. It provides immediate-mode building blocks for creating nodes, pins, and links inside ImGui windows, with users controlling all state.

## Use cases
- build a node-based editor UI inside an ImGui application
- create visual shader or material graph editors
- add node graph editing to a game engine tool
- embed a visual scripting workspace in a C++ desktop app
- nest arbitrary ImGui widgets inside draggable nodes
- prototype dataflow or pipeline editors in immediate-mode GUI

## When to choose
- you already use dear imgui and need node editor functionality
- you want a minimal, copy-paste dependency with no extra libraries
- you prefer immediate-mode style where your code owns all state
- you need customizable low-level building blocks rather than a fixed editor

## When to avoid
- you need a full-featured standalone node editor application
- your project does not use dear imgui
- you need a retained-mode or batteries-included graph framework
- you require guaranteed Linux build support, which is untested upstream

## Facets
- artifact type: library
- maturity: active
- function: ui-components, graphics, developer-tools
- domain: graphics, developer-tools, cross-platform
- platform: cpp, cross-platform
- tags: imgui, node-editor, immediate-mode, visual-programming, gamedev, header-only-style, game-development, desktop
