About Code Practice Hub

Code Practice Hub is a free, browser-based coding practice platform. There is no account to create and nothing to install — you open the site, choose a language, and start writing code.

Why we built it

Setting up a development environment is often the hardest part of learning to code. Compilers, interpreters, database servers — it adds friction before a beginner writes a single line. We removed that friction. The editor, the runtime and a sample SQL database are all one click away.

What you can practise

• JavaScript, Node.js, Python, C, C++, Java and PHP.
• HTML and CSS with a live preview.
• SQL and MySQL queries against a ready-made dummy database with five sample tables.

How it works

JavaScript, HTML, CSS and SQL run entirely inside your browser for instant feedback. Compiled and interpreted languages run on a secure, sandboxed execution engine. Your code and notes autosave locally so a page reload never loses your work.

Who it is for

Students, self-taught developers, teachers preparing examples, and anyone who wants a fast scratchpad for code. If you are learning, this is your practice ground.
