Why Technical Writers & Educators Choose ZenCompiler

Unlike static code blocks that readers can only copy-paste, embedded ZenCompiler widgets let readers run, modify, and experiment directly inside your article.

Sub-50ms Cold Starts

Cloud worker containers are warm and ready instantly. Readers get instant output without waiting for bloated environments to spin up.

Real Linux PTY Terminal

Supports interactive user prompts (input(), cin >>, scanf). Users can type input directly into the running program.

Zero Maintenance & 100% Free

No server costs, no API keys, and no sandbox maintenance. ZenCompiler securely executes all container workloads for free.

How to Embed in Your Platform

WordPress & Ghost CMS

Add a "Custom HTML" block in the Gutenberg or Ghost editor and paste the copied iframe code directly into the block.

React & Next.js Sites

Drop the `<iframe>` snippet inside JSX or create a custom React component using `dangerouslySetInnerHTML` or an iframe element with `allow="clipboard-write"`.

Docusaurus & GitBook

Raw HTML iframes work natively inside Markdown (`.md` / `.mdx`) documentation files. Simply paste the snippet into any tutorial chapter.

Webflow, Notion & Medium

Use the Webflow "Embed Component" or Notion "Embed" block with the URL: https://zencompiler.com/embed/python?theme=zen-dark.

Embed Widget FAQs

Frequently asked questions about embedding ZenCompiler widgets.

Can users edit the code in the widget?

Yes! Readers can freely edit the code, add print statements, test different inputs, and re-run. Their modifications are local to their browser session and do not overwrite the original snippet.

Are there any rate limits on embedded runners?

We apply standard anti-spam limits (1 run per second per user) to protect container resources, but there are no daily execution quotas for standard blog readers.

Can I pre-fill the widget with custom code?

Yes! You can append URL encoded code to the iframe source query: ?code=encodeURIComponent("...") to display any specific algorithm or example.

Does it work seamlessly on mobile?

Yes. The widget automatically switches to an optimized mobile tab bar allowing smartphone readers to toggle effortlessly between code editing and execution output.
