In response to your requests, we've prepared a browser-based version of the C language development environment!
Start programming in C right now from your browser.

Running in the Browser

C Language Execution Environment



One-Click Installation


The file size is just 3MB.With just that, you have everything you need: an editor, a compiler, a runtime environment, and all the essentials for learning to program.
You don't need long downloads, complicated setups, or plugin installations.
You can start programming right now!

Automatic Project


You only need to provide the program's input!
Upon startup, the project will be automatically created and multiple source files will be automatically recognized.
The editor automatically manages tedious build configurations.You can focus on programming.

Japanese error message


Error messages are available in Japanese!
If there are any errors in the program, this app will tell you in Japanese.
Even when learning alone, you can progress by figuring things out on your own.


A genuine C language compiler


The Tiny C Compiler is used as the compiler.
It's a genuine compiler that supports all features of the C language and outputs native code.
We also made our own modifications to accommodate Japanese.


Lightweight operation


The editor is developed natively for Windows.
We've achieved a natural and seamless operation, feeling completely native as a Windows application, with exceptional speed and responsiveness.
It runs smoothly even on low-spec PCs.


Color display compatible


We adopted Azuki as our code editor.
It's a highly experienced text input function that operates very smoothly.
Of course, it supports essential features for programming, such as color display and automatic indentation.



The continuation of Learning C the Hard Way is here.
