Regex Hero vs RegExr

Regex Hero is a.NET regular expression tester for writing patterns and checking their behavior in.NET applications. The web tester runs in real time and highlights matches as users type. Its editor includes regex syntax highlighting and code completion, and the site provides a.NET regular expression reference. Users can generate C# and VB.NET code from patterns. A community library lists 179 regular expressions in categories such as email, validation, CSV, and password. Regex Hero is available on the web and Windows, and its tester page links to a Microsoft Store download. The home page says a Mac version is not yet available. The product is free: the Regex Hero Professional plan costs nothing, with no exact current plan limits stated. The news page announced that Professional became free in July 2017. BucketSoft, LLC is the maker; its about page says Steve Wortham founded the company in March 2009. Wortham provides support by email and through a forum for ideas and bug reports. The privacy policy says collected information may include names, email addresses, and browser information for analytics. It also says submitted ratings, reviews, and feedback may be displayed, reused, and distributed.

RegExr is a free web tool for learning, building, and testing regular expressions. It supports JavaScript and PHP/PCRE expressions, with results that change as you type. Hovering over a match or expression reveals details, and the Explain tool describes an expression in plain English. Tests mode lets users assemble examples that an expression should match or reject. Replace and List produce custom outputs, while Details shows capture groups. Learning resources include a cheatsheet, reference, help pages, and examples. Users can search and rate Community Patterns, then save and share expressions. Signing in keeps favorites and patterns in My Patterns. A saved expression gets a public link, and a Community-shared copy cannot be edited or deleted. The listed RegExr plan costs nothing. The project README credits Grant Skinner and gskinner.com as creators and identifies this version as GPL v3 licensed. It directs issue and feature requests to GitHub and regular-expression questions to Stack Overflow.
