In their own words
Regex Hero
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.

Retest
Retest is a free, open-source terminal utility for developing and checking regular expressions on Linux. A subject string can be supplied as an argument or piped through standard input, so it can fit into shell workflows. Retest finds all non-crossing matches and highlights nested capture groups in colors distinct from the whole match. An optional formatted list shows match order and string indexes. Release 0.2.2 added a flag for reading the subject from a file. The project provides Linux release binaries, including a 64-bit Debian installer listed for release 0.2.2. Its README describes compiling from source with Cargo and installing through a Makefile. The source code and documentation are licensed under Apache License 2.0. The project presents Retest as a terminal-based alternative to regex101, for developers building and checking patterns. No paid plans or usage limits are listed.
