GoCode Online Compiler Now Runs 12 Languages

The GoCode online IDE has grown up. What started as a compiler for five languages now runs twelve — everything from Python and Java to Go, Ruby and a live web playground — all in your browser, with no install and no setup.

The full language list

• Python — the go-to for learning, scripting and interviews.
• Java and C# — the workhorses of enterprise and campus placements.
• JavaScript and TypeScript — the language of the web, typed and untyped.
• C and C++ — for systems, competitive programming and fundamentals.
• Go — fast, simple and increasingly asked for in backend roles.
• PHP and Ruby — still powering a huge share of the web.
• Web (HTML/CSS/JS) and React — a live playground that renders as you type.

How it works

Open the IDE, pick a language from the dropdown, and hit Run. Compiled languages build and execute server-side; the web and React modes render instantly in a sandboxed preview right next to your code. You can pass input through stdin, and the editor autosaves your work.

Why we did it

Learners shouldn't have to install a toolchain just to try an idea. Whether you're revising for a placement test in Java, exploring Go for the first time, or building a small web page, you can now do it in one place. Pick a language below and start writing code.
