A regex is only trustworthy when it has been tested against examples that should match and examples that should not. RegExpress v7 leans into that workflow with generated test suites, a larger free tier, and Pro trials that let users evaluate advanced tools before buying.
The Free Tier Is More Useful
RegExpress v7 lets free users save up to 20 patterns, keep 50 history items, use folders and search, access basic export, and start with 3 tutorial modules. That is enough to build a real pattern library and decide whether the deeper Pro workflow is worth it.
Test Suites Turn Regex Into Something You Can Maintain
Workspace test suite generation can create test cases from the current editor, connect them to a pattern, and open the generated suite for regression testing. This matters when you refine a pattern over time: you can check that new edits do not break old assumptions.
Pro Trials Reduce Guesswork
Several Pro tools can be tried before upgrading, including visual debugging, pattern optimization, pattern construction, visual diagrams, pattern recommendations, pattern comparison, test suites, and code generation. The goal is straightforward: evaluate the workflow with your own patterns before committing.
Pro Is a One-Time $4.99 Upgrade
RegExpress Pro unlocks unlimited saves and history, iCloud sync, advanced tutorials, test suites, visual debugging, pattern optimization, pattern comparison, visual diagrams, code generation, and more. It is a one-time $4.99 purchase, not a subscription.
