“RegexBuddy 4 is an amazing tool for working with regular expressions! Earlier composing regular expressions was a PITA but now a breeze without going around try and fail circle several times.”

“Learning regular expressions thoroughly with RegexBuddy has been one of the most useful computing things I’ve ever done. And though I’m getting very fast with 90% of the regexes I do, there always seems to be one that I still want to paste into RegexBuddy to find quickly what error I made.”

“My done code so far can be clearly divided into pre and post RegexBuddy times. I knew all about regexes before and used them if needed, but without RegexBuddy, debugging took longer than writing code. After buying RegexBuddy I use regexes wherever useful, reduce code and finally have time for real business logic.”

“I bought RegexBuddy 5 years ago. I think there are less than 30 working days than since, that I did not use it. I got all the free updates/bugfixes over the years and finally asked myself: WHY? I was more than willing to pay for updates after two years or so but it was always free. This is really fair and best practice for consumer satisfaction.
“As a coder I know that a software is never ‘finished’. But I always thought that regexbuddy 3 is as closed as possible to this state. When I got your mail about version 4 I was surprised. You really managed to add THIS lot of valuable things under the hood; leaving the interface intact—I am really impressed. Coding is one thing, concurrently knowing about UX a complete other.”
