## What it is
Nuklear is a minimal, single-header immediate mode graphical user interface toolkit written in ANSI C (C89) with no dependencies and no default render backend. This original repository is abandoned; all development has moved to the Immediate-Mode-UI/Nuklear organization.

## Use cases
- add a gui to a c or c++ application
- embed a lightweight ui toolkit in a game or tool
- build an immediate mode interface with full memory control
- render ui on any backend since only draw commands are output
- create a portable gui without pulling in dependencies

## When to choose
- you need a tiny, dependency-free, embeddable immediate mode gui in C
- you want full control over memory, rendering, and platform integration
- you target C89 or highly constrained environments

## When to avoid
- you want a maintained project - use Immediate-Mode-UI/Nuklear instead
- you need a batteries-included gui with default rendering and window handling
- you want retained-mode widgets or native platform look-and-feel

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, gui
- domain: cross-platform, developer-tools
- platform: cross-platform, cpp, c
- tags: immediate-mode, single-header, c89, imgui, embeddable-ui, no-dependencies, game-development
