## What it is
Wandbox is an online compiler service (wandbox.org) that lets users write, compile, and run code snippets in dozens of languages — C++, Rust, Haskell, Elixir, Zig, and many more — through a web UI or a public HTTP API. This repository contains the source code for the service, which can also be self-hosted, and pairs with the wandbox-builder project that supplies the compiler toolchains.

## Use cases
- compile and run code snippets online without installing a toolchain
- test code against many different compilers and language versions
- share a runnable code snippet with others via a link
- run code from editors like Vim or Emacs through the API
- try out an unfamiliar programming language quickly
- check how a snippet behaves across compilers before committing it

## When to choose
- you need quick, zero-setup experimentation with code in many languages
- you want to integrate compile-and-run checks into editors or scripts via an HTTP API
- you teach programming and want students to execute code without local setup

## When to avoid
- you need an SLA or guaranteed uptime for production-critical workloads
- you need private dependencies, long-running jobs, or heavy resource usage
- you want a supported self-hosted deployment — self-hosting is explicitly unsupported
