iHateRegex.io is a web application and regex cheat sheet that helps users understand, test, and share regular expressions. It provides visual railroad diagrams, plain-English explanations, live match highlighting, and a community library of practical patterns.

Use cases

• find a regex for validating email addresses
• understand what a regex pattern does
• test a regex against sample strings
• visualize a regex as a railroad diagram
• share regex patterns with a team
• learn how to write regular expressions
• find regex for phone numbers or IP addresses

When to choose

• you need a quick, well-documented regex for common validation tasks
• you want to visually understand how a regex works
• you want a playground to test and share regexes

When to avoid

• you need a programmatic regex library to embed in your code
• you need offline regex tooling without a web app
• you need advanced regex features beyond testing and visualization
