What RegexBuddy is
RegexBuddy helps people create, understand, test, debug and save regular expressions. Its builder assembles patterns from descriptive components and displays their structure in a tree. Users can test patterns against sample data or files, step through matches and inspect how the matching process works. The software supports 94 regex flavors, including PCRE, PCRE2, .NET, JavaScript, Java, Perl, PHP, Python, Ruby, Boost, RE2, ICU and POSIX BRE/ERE. It can compare flavors and convert patterns between them, using equivalent syntax where possible and warning about behavioral differences. RegexBuddy also creates language-specific snippets for matching, extraction, search and replace, and splitting. A built-in GREP tool searches and replaces across files and folders. It is a desktop product for Windows; there is no native Linux version, though the Windows edition can run under Wine with documented glitches and limitations. There is no free plan or evaluation version. A single-user license costs £44.95, paid once, excluding taxes; licenses range up to £1,599, paid once for 100 users, also excluding taxes. Licenses include email support and minor updates and bug fixes.
