Features
Everything you need in Brainy Compiler.
Brainy Compiler is a fast online compiler and code runner. Pick a language, write your program in the same editor that powers VS Code, feed it standard input and hit Run: output, compiler errors and runtime errors appear in the console within moments. It supports Python, C, C++, Java, JavaScript, TypeScript, C#, Go, Rust, Kotlin, PHP and Swift, and works just as well on a phone as on a lab computer.
12 languages, one place
Python, C, C++, Java, JavaScript, TypeScript, C#, Go, Rust, Kotlin, PHP and Swift, switchable from a single menu.
A real code editor
Built on Monaco, the editor behind VS Code, with syntax highlighting, bracket matching and a minimap.
Custom standard input
Type the input your program reads and test it against exactly the cases you care about.
Clear output and errors
Program output, compiler messages and runtime errors land in a dedicated console, so you can see what went wrong.
Starter templates
Switching language loads a ready-to-run starter program, so you never begin from a blank page.
Works on any device
A split-pane layout on desktop and a stacked, touch-friendly layout on phones and tablets.
