Compiler Explorer

Hello there!

Compiler Explorer lets you interactively explore how your C++, C, D, Rust, Pascal, and other compiled language code turns out after the compiler has worked its magic. It shows an annotated assembly window, and allows you to tweak your code and compilation settings and see how that affects the output. It also lets you run your code.

Compiler Explorer started life in 2012 and has grown from a funny little website (then called "GCC Explorer" as that's all it supported) to a pretty significant resource for learning about compilers, optimisation and teaching C++ and other languages.

Compiler Explorer is easy to set up and run locally, but is mostly known for the godbolt.org site (indeed, many folks call it "Godbolt", to Matt's embarrassment!). The site handles around 150,000 compilations a day.

Your support helps run the site: as you might imagine it can be pretty costly to host and handle that amount of traffic. It also helps pay for monitoring and log aggregation, and obviously inspires us to spend more time developing it!

Compiler Explorer's source is completely open, as is nearly all of its AWS configuration and infrastructure for building all the 1000+ compilers. The only thing not open are the commercial compilers and their license keys.

Thanks for reading this: and for any support you might be able to give. We appreciate it so very much.
