About
C3 Playground is a browser-based compiler and runtime for the C3 programming language that executes entirely client-side via WebAssembly. It lets users write and run C3 code, including interactive graphical programs and Raylib-based demos and games, without installing a local compiler.
At a glance
C3 Playground is an online editor and console for small C3 programs. It is worth opening if you want to try the language’s syntax before setting up a compiler and project locally.
Good fit
C programmers comparing basic syntax, module imports and compiler diagnostics in a small example.
Consider something else when
Use a local project for private code or when you need to verify native build and integration behavior.
Start here
Try the documented Hello World example with a distinctive output string. Change one line to trigger a diagnostic and compare the result with the language guide.
Cost and requirements
The public playground exposes an editor, compiler flags and a console in the browser. The official language guide also covers local compilers.
Limits to know
The public sources reviewed do not establish where submitted code is compiled or retained. Use short synthetic snippets.

Why it made the leaderboard
It lets developers write and run interactive C3 graphics/audio demos entirely in the browser, useful for exploring the language without a local toolchain.
