Regex Hero vs RegEx Visualizer & Explainer

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.

RegEx Visualizer & Explainer is a browser tool for testing and debugging regular expressions. As a pattern is entered, it highlights matches and shows match and capture-group details. The tool explains individual tokens and provides a step-by-step debugger. Test mode checks pattern matches, Replace mode previews substitutions, and Diff mode compares two patterns. Test cases, presets, a cheatsheet, and browser history are also included. Matching uses the browser’s JavaScript RegExp engine and supports its regex flags. Testing runs in the browser; the page says content stays on the user’s device unless they copy or download a file. The tool runs on the web without installation or an account, and the Free plan costs nothing. It does not provide a multi-language code export panel, so patterns should be retested for differences in a target language. ToolsViewer describes its collection as intended for developers, students, designers, and other professionals. Support requests can be sent by email, with replies targeted within a few business days.
