## What it is
A wiki-based cheat sheet cataloging techniques for bypassing browser XSS (cross-site scripting) filters. It serves as a reference for security researchers and penetration testers studying filter evasion payloads.

## Use cases
- find ways to bypass browser XSS filters
- reference XSS filter evasion payloads during a pentest
- learn how browser anti-XSS filters can be circumvented
- study cross-site scripting filter bypass techniques
- look up XSS payload examples for security testing

## When to choose
- you are doing security research or penetration testing on browser XSS filters
- you need a curated reference of XSS filter bypass techniques

## When to avoid
- you need a tool or library to scan or fix XSS vulnerabilities rather than a reference document
- you want actively updated content - the project has not seen releases since 2017

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: security, penetration-testing
- domain: security, penetration-testing, web-development
- platform: browser
