A free online Python IDE that needs no account

Most "free" online Python editors ask you to sign up before you can run a single line, or lose your work the moment the tab closes. This one does neither. Open the page, type Python, press Run. There is no account, no email address and nothing to install — and your code is still in the editor when you come back tomorrow.

Your code runs entirely on your own device, inside the browser tab, using a Python interpreter compiled to JavaScript. Nothing is uploaded to a server; your work is kept only in your own browser's storage. That matters in a school: it means the editor works on a locked-down Chromebook or a managed school PC where you cannot install software, and it keeps working when the network filter blocks the usual coding sites.

A fuller breakdown, with what each one is actually like to use in a lesson, is in our guide to the best free online Python IDEs for students.

Built around GCSE and A-Level Computer Science

The editor is free for anyone, but it was written for the UK exam specs. AQA (8525 and 7517), OCR (J277 and H446) and Edexcel (1CP2 and 9CP0) all require you to write, trace and debug real programs, and every one of them examines the same core: sequence, selection, iteration, functions, arrays and lists, string manipulation and file handling.

If you want structure rather than a blank editor, a free BrightRevision account adds Python coding challenges for GCSE Computer Science — exam-style tasks that are marked instantly against hidden test cases, with hints when you get stuck and a record of which topics you keep dropping marks on.

Questions about the Python editor

Is this Python IDE completely free?

Yes. The editor, the examples and the open/save tools are free with no account and no limit on how much you use them. A paid BrightRevision subscription adds marked coding challenges, quizzes and progress tracking, but nothing on this page is behind it.

Do I need to install Python or create an account?

Neither. Python runs inside the browser tab on your own device, so there is nothing to download and no sign-up. It works on a school Chromebook, a managed school PC, a Mac, or a phone.

Does input() work?

Yes. The output pane is interactive, so a program that calls input() pauses and waits for you to type an answer, exactly as it would in IDLE or a terminal.

Can I import libraries like random or math?

The common standard-library modules used at GCSE and A-Level — including random, math, time and string — are available. Third-party packages such as numpy or pandas are not, because everything runs on your device rather than on a server.

Is my code saved or sent anywhere?

It is never sent anywhere — your code does not leave your device. It is kept in your browser's own storage, so it is still there next time you open the page on the same device and browser. Clearing your browser data will remove it, so use Save to keep a copy as a .py file for anything important.

Why did my program stop with a timeout?

Code is given 10 seconds to run before it is stopped. Because everything runs in your browser tab, an infinite loop would otherwise freeze the page — the limit is what lets you close a runaway while loop without losing your work. Normal GCSE and A-Level programs finish in a fraction of a second.
