Siv3D (formerly OpenSiv3D) is a C++20 framework for creative coding, supporting 2D/3D games, media art, visualizers, and simulators. It provides graphics, audio, input, networking, and math features and runs on Windows, macOS, Linux, and the Web.

Use cases

• build 2d games in c++
• create 3d games with a c++ framework
• make media art installations
• build audio visualizers
• write interactive simulations
• creative coding with c++20
• cross-platform game development in c++

When to choose

• you want a batteries-included C++20 framework for games or creative coding
• you need cross-platform deployment including WebAssembly
• you want built-in graphics, audio, input, and math without assembling libraries

When to avoid

• you need a production-scale 3D engine with advanced rendering pipelines
• you prefer engines with visual editors like Unity or Godot
• you are working in a language other than C++
