Category: devtools

Tags: demoscene, webassembly, polyglot, graphics, compiler-comparison

Score: 7.0/10 (Innovation: 7, Technical: 9, Documentation: 8, Utility: 4)

Babeltro implements nine classic demoscene effects in thirteen languages, all producing pixel-identical output to a C reference. It runs live in the browser via WebAssembly, with optimization ladders, side-by-side code comparisons, and a race mode, making it a unique educational showcase of language semantics and compiler behavior.

Target audience: developers interested in compilers, language internals, and demoscene graphics; educators and students of systems programming
