Regex Match Lab vs API Nauta

Build, test, and reuse regular expressions without sending your text anywhere. TEST PATTERNS LIVE Enter a pattern and sample text to see matches update as you work. Toggle ignore-case, per-line anchors, and dot-matches-newline options. SEE EXACT MATCHES Matched text is highlighted in place and plotted on a compact match map. Every result includes its exact source range. INSPECT CAPTURE GROUPS Open each match to see numbered capture groups, captured values, and ranges. Use the included email, log, and date examples as practical starting points. PREVIEW REPLACEMENTS Switch to Replace, enter an NSRegularExpression replacement template, and review the complete transformed text before using it elsewhere. SAVE REUSABLE TESTS Name useful pattern-and-sample combinations, update them, reopen them after relaunch, or share a plain-text result report. BUILT FOR REAL WORK The adaptive workbench fits iPhone and iPad. Large samples and result counts are bounded to keep previews responsive. PRIVATE BY DESIGN Tests stay locally on your device. There is no account, analytics, tracking, advertising, cloud upload, or server connection.
