I built a regex API because regex101 has no backend for my apps on RapidAPI

Need to test/parse regex in your backend but don't want to spawn a JS process?

So I built this: https://rapidapi.com/studio/api\_31f72198-a68c-4cba-9382-2502dd953b74/publish/general

What it does:

  1. **Test regex against text via API** - POST your pattern + flags + test string

  2. **Returns matches + groups + indexes** - Full JSON response, no scraping

  3. **JS/PCRE support** - Handles `/café/gi` unicode properly

  4. **Explain endpoint** - Get human-readable breakdown of your pattern

Free tier on RapidAPI. Built this because I kept needing regex in Lambda without bundling a full engine.

Roast it. What endpoints are missing? What would make you use this over rolling your own?

If it breaks, tell me. Just launched and need devs to break it.

I built a regex tester that actually handles unicode + explains matches [Free]

Was debugging regex for 2 hours because regex101 choked on café with /i flag.

So I built this: https://ex-tester.vercel.app

Why it's different:

  1. Proper JS unicode support - /café/gi actually works
  2. Explains each match, not just highlights
  3. No ads, no login, instant
  4. Dark mode because we're not animals

Roast it. What's missing? What would make you switch from regex101?

If it breaks, tell me. I just launched and need real devs to bully-test it.
