I continue to work on Aba Search and Replace, a tool for regex search and quick conversions (Base64, URL encoding, JSON Web tokens, timestamps to dates and vice versa). https://www.abareplace.com/
I continue to add more features to my search-and-replace tool for Windows (https://www.abareplace.com/). I initially built in for myself and it was one of the first incremental grep implementations (allowing you to see the results as you are typing the search pattern). Now it supports various formats like Base64, URL encoding, or timestamp conversions. With one-liners, you can add width/height attributes to <img> tags or insert file contents.
Agreed, the lack of borders or indentation on the screenshots is very confusing. It's hard to understand what text comes from the malicious website and what is from the author.
I wrote a tool for replacing text in multiple files with regular expressions under Windows. Currently, it's making less than $500/month, but there were months when it made more. It's one of the first regex tools that displays the search results immediately, without pressing a Search button.
