How it works
Point Helix at the checkout, cart, homepage, or form that makes you money.
Helix runs checks every minute so you don’t have to babysit your store.
Get notified the second something breaks so you can fix it before sales disappear.
What proof looks like
Here’s exactly what happens when checkout fails.
We confirm it’s not a fluke by running a second check immediately.
Email hits your inbox (SMS coming soon) with the exact failing page and status code.
Helix confirms three healthy checks in a row and sends the RECOVERED alert so you know it’s safe.
Stores lose sales every day from broken checkouts—most never realize it until hours later.

Founder reviews
★★★★★
“Helix caught a bad Shopify shipping-app update within 4 minutes. We paused the launch, fixed it, and saved a weekend’s worth of orders.”
★★★★★
“The $2 plan paid for itself day one. We got a DOWN alert during a paid drop, jumped in, and kept ROAS from tanking.”
★★★★☆
“Love that it’s external. No code, no app—just honest alerts in my inbox so I’m not guessing if checkout is alive.”

Why Helix exists
