The debugging tools are top-notch and have saved us countless hours. Its clear and intuitive presentation of matches significantly improves our workflow. Highly recommend!
While RegEx Testing (Mozilla) is a solid tool, I've found it occasionally struggles with very complex regex patterns. It's good for most day-to-day use cases, and the integration with Firefox is seamless. The lack of advanced features, like regex profiling, holds it back. However, it's a decent free option overall, especially for quick tests.
As a DevOps engineer, I rely heavily on regular expressions for scripting and automation. RegEx Testing (Mozilla) is a valuable tool for quickly validating and refining my regex patterns before deploying them. I appreciate the ability to save and organize my regexes for later use. The integration with Firefox allows easy access and seamless implementation of tested patterns. I would recommend this to other engineers.
