The Regex Tester Landscape
Regular expressions are one of the most powerful (and confusing) tools in a developer's arsenal. Having a good tester is essential.
Privacy vs Features
Regex101 is the feature king — debugger, community library, multi-language support. But it sends your test strings to their servers. If you're testing patterns against customer data or logs, that's a privacy risk.
When to Use Each
Testing a regex against sensitive log data? Use DevUtility. Learning regex or debugging a complex pattern? Regex101's debugger is unmatched. The best approach: use both for different scenarios.
