Can Python Run On The Brower

Python Programming

As a developer, I’ve often wondered about the possibility of running Python code directly in a web browser. It would be incredibly convenient to use Python for web development without the need for server-side processing. So, can Python run on the browser? Let’s dive into this fascinating topic and explore the options available.

Client-Side Python Execution

Traditionally, web browsers have not been capable of executing Python code directly. Browsers inherently support HTML, CSS, and JavaScript, but not Python. However, innovative projects have emerged to bridge this gap and enable Python execution in the browser.


Brython is a Python 3 implementation for client-side web programming. It allows developers to write web applications entirely in Python and execute them within the browser. This is achieved by translating Python code into equivalent JavaScript, which can be run by the browser. While Brython provides a way to write Python for the web, it’s important to note that not all Python libraries are compatible with it.


Skulpt is another project that brings Python to the browser. It is an entirely in-browser implementation of Python. Similar to Brython, Skulpt translates Python code into JavaScript to enable execution within the browser environment. Skulpt has gained popularity for educational purposes, allowing students to learn and practice Python directly in the web browser.

WebAssembly and Python

WebAssembly (Wasm) is a binary instruction format for a stack-based virtual machine, designed as a compilation target for high-level languages like C/C++ and Rust. While Python is not natively supported by WebAssembly, there have been efforts to explore the feasibility of running Python code through Wasm.


Pyodide is a project that leverages WebAssembly to bring Python to the browser. It includes the entire Python scientific stack, including NumPy, Pandas, Matplotlib, and more, allowing data science and scientific computing to be done entirely in the browser. Pyodide opens up exciting possibilities for running Python in web applications, particularly in the domain of data visualization and analysis.


While Python’s native execution in web browsers is not yet a standard feature, the availability of projects like Brython, Skulpt, and Pyodide is pushing the boundaries of what’s possible. As I continue to explore the intersection of Python and web development, I’m excited to see how these initiatives evolve and potentially shape the future of web programming. The prospect of writing Python code and seeing it run seamlessly in a browser is both intriguing and promising.
