## What it is
TinyGLTF is a header-only C11/C++ library for loading and saving glTF 2.0 3D asset files. It offers a pure C POD API, arena-based memory management, structured error reporting, and hardening against untrusted input.

## Use cases
- load gltf files in c or c++
- parse 3d models for a game engine
- write gltf 2.0 assets programmatically
- parse untrusted gltf files safely
- embed a lightweight gltf loader without dependencies
- bind gltf parsing to other languages

## When to choose
- you need a small, dependency-free glTF 2.0 loader/writer in C or C++
- you must parse untrusted glTF assets and want hardened, fuzz-tested parsing
- you want easy language bindings via a pure C API
- you need fine control over file and image I/O

## When to avoid
- you need a full scene graph or rendering engine, not just asset parsing
- you work in a language other than C/C++ without writing bindings
- you need loaders for formats other than glTF

## Facets
- artifact type: library
- maturity: active
- function: parser, serialization, graphics, file-system
- domain: graphics, files, developer-tools
- platform: cpp, c, cross-platform
- tags: gltf, header-only, 3d-assets, single-file-library, fuzz-tested, game-development
