Overview

The codebase behind the Wandbox online compiler, offering many languages and compiler versions plus permalink sharing of code, input, and results, now built around a TypeScript frontend and Rust backend.

Why we discovered this

A Japanese indie service sustained since 2012. Its 2025 rewrite from the old C++ backend to Rust while preserving a permalink workflow used in real university courses makes it a notable long-lived OSS project.
