Online Python MarkupSafe Compiler
MarkupSafe is a Python library that implements a text object that escapes characters so it is safe to use in HTML and XML. Characters that have special meanings in markup languages are replaced so that they display as the actual characters rather than being interpreted as markup. This mitigates injection attacks, meaning untrusted user input can safely be displayed on a web page without risk of XSS (Cross-Site Scripting) attacks or other security vulnerabilities.
This compiler includes MarkupSafe 3.0+ with full support for HTML and XML escaping, powered by Pyodide WebAssembly technology. MarkupSafe provides the escape() function to safely escape untrusted strings and the Markup class to mark trusted strings as safe. The library is a core dependency of many web frameworks including Flask and Jinja2, making it essential for web development security. Whether you're building web applications, processing user input, generating HTML templates, or working with untrusted data, our MarkupSafe playground offers instant execution with comprehensive security features. You can escape HTML/XML special characters, mark strings as safe, use Markup objects in string operations, and protect your applications from injection attacks. You can also upload and use files or folders directly in your code for text processing workflows. This compiler is online and completely free to use.
Our example collection covers essential MarkupSafe topics including basic HTML escaping, using Markup objects, string formatting with safe strings, escaping user input, and protecting web applications from XSS attacks. You'll learn how to safely handle untrusted strings, mark trusted content as safe, and integrate MarkupSafe into web applications for secure text rendering.
