Embed Runnable Python Code in Any Website

One iframe tag turns a static code sample into a live editor your readers can run and modify — on your blog, in your docs, or inside your course. Free, no account, no API key.

How It Works
  1. Paste your code into the generator above (or click Embed in the editor to copy an embed for whatever you're working on).
  2. Copy the iframe tag and paste it into your HTML, a WordPress Custom HTML block, Ghost, Notion, or your LMS's embed field.
  3. That's it. Readers see your code in a live editor. When they press Run, Python 3.13 executes right in their browser and the output — including Matplotlib plots — appears below the code.
One honest limitation: input() prompts aren't available inside embeds — assign values to variables instead, or let readers jump to the full editor with the built-in “Open in full editor” link.
Why Embed with pythoncompiler.io
Zero Setup for Readers
No install, no account, no "clone this repo first." Readers press Run and see output in seconds — and they can edit your example to experiment, which is how people actually learn.
Nothing Touches a Server
Code executes in each reader's browser. There is no backend to rate-limit you, no queue at peak times, and no privacy questions about where your readers' code goes.
Fits Your Page
Dark and light themes, any height, responsive width. The widget stays out of the way until a reader interacts with it — the Python runtime loads only on the first Run click.
Built for Teaching
Drop working examples into course pages, homework instructions, or documentation. NumPy, Pandas, and Matplotlib work out of the box — plots render right inside the widget.
Frequently Asked Questions
How do I embed runnable Python code in my website?
Paste your code into the generator on this page, copy the iframe tag it produces, and add it to your HTML, WordPress post (in a Custom HTML block), Notion page, or LMS. Your readers get a live editor where they can run and modify the code — no plugin or API key required.
Is the embed widget free?
Yes, completely free with no usage limits, no account, and no API key. The widget shows a small "Powered by pythoncompiler.io" credit link.
Does embedded code run on a server?
No. The code runs entirely in each reader's browser. Nothing is sent to a server, there are no execution queues, and your page stays fast — the Python runtime only loads when a reader clicks Run.
Which Python features are supported inside embeds?
Python 3.13 with the full standard library, plus NumPy, Pandas, and Matplotlib (plots render inline). The one limitation: input() prompts are not supported inside embeds — use variables instead. For interactive input, readers can click "Open in full editor."
Does the embed slow down my page?
No. The iframe loads lazily and only the lightweight editor loads at first. The Python runtime downloads only when a reader actually clicks Run, so your page speed and Core Web Vitals are unaffected.
