Test Regex on
Secure Payloads.
Pasting proprietary server logs or user API payloads into cloud-based regex testers is a massive security vulnerability. Test regular expressions entirely inside your local browser sandbox.

Zero Leakage Sandbox
Match operates entirely locally. No API calls, no cloud processing. Paste your production DB logs to test queries without risking compliance breaches.
Visual Highlighting
Real-time syntax matching. The moment you type a valid regex boundary, the target payload strings illuminate with exact character precision.
Built-In Syntax Guide
Regex is notoriously hard to remember. Match features an always-visible, native cheatsheet covering anchors, quantifiers, and capture groups.
Under the Hood
The architecture powering Lumist Match.
Native V8 Parsing
Match doesn't attempt to build a fragile custom regex interpreter. It passes your string directly to your browser's underlying JavaScript V8 Engine (using `RegExp`), guaranteeing 100% execution accuracy for JS/TS environments.
Lumist Stash Integration
When you finally craft that perfect, complex extraction pattern, you can send it directly to Lumist Stash with a single click, saving it to your local IndexedDB for future retrieval.
Frequently Asked Questions
Why shouldn't I just use regex101.com?
Cloud-based regex testers process your data on remote servers. If you are testing extraction patterns against raw database dumps, customer emails, or JWT tokens, pasting them into a third-party tool is a severe security and compliance vulnerability.
Does this support PCRE or Python-specific regex flavors?
Lumist Match uses standard ECMAScript (JavaScript) regular expressions, which share the vast majority of syntax with PCRE, Python, and Go, making it perfect for web developers and frontend engineers.
