C3 Playground
An in-browser playground that compiles and runs the C3 programming language entirely in WebAssembly, with no backend server, alongside its standard library and documentation.

C3 Playground lets a visitor write C3 source code in the browser and compile and execute it immediately, entirely through WebAssembly with no server-side backend involved. It shows compiled console output alongside the source, and one built-in example renders a synthwave-style voxel-space landscape with graphics and sound to demonstrate the language.
The playground links out to C3's standard library reference and its documentation, making it a self-contained way to try the language, including examples that produce graphics or audio, without installing a compiler.
