About

We think a broken checkout should never be a surprise.

Checkout Monitor exists for one reason: too many stores lose sales for hours before anyone notices the "Buy" button stopped working. We built the tool we wished we'd had.

Signed
HMAC-authenticated Store API calls, replay-protected.
2-strike
Alerts only fire after two consecutive failures. No flake-storms.
Invisible
Test orders suppressed from admin, emails, analytics.
$0
Spent on real orders — bot-only test gateway, never charges a card.
Our story

It started with a checkout that broke for two days.

A plugin update quietly broke the payment step on a store we ran. Traffic looked normal, the homepage loaded fine, ads kept spending — but not a single order came through. We only found out when a customer emailed to complain.

Uptime monitors said everything was green, because to them it was. Nothing actually tried to buy anything. So we built something that does — every minute, using the same signed API path a real customer's browser takes.

A green ping is not proof of a sale. The only real check for a checkout is buying something. Everything else is a guess in a nicer font.

The premise we build on.
What we believe

Principles we build on.

Test the real thing

A green ping isn't proof of a sale. We measure what actually matters: can a customer complete a purchase right now?

Alert, don't spam

Two-strike suppression means we only interrupt when something is real — with the exact step and a plain-language cause.

Never touch real money

The bot-only test gateway never touches Stripe / PayPal / any real payment provider. Test orders suppressed from every merchant surface.

How we work

Small team, one obsession.

Independent, revenue-focused. Store operators and engineers who've felt the pain of a silent failure firsthand.

Built in the open

Every change ships as an atomic commit through code review + CI (Pest / Vitest / Node). Public roadmap; honest changelog; no vaporware in the pricing page.

Product-first

The free tier is a full-featured product, not a bait tier. If a feature belongs in monitoring, it's in every tier — paid tiers add capacity, not core value.

Security as a habit

Every runner → plugin request is HMAC-signed, timestamped, and nonce-protected. Secrets AES-encrypted at rest. Fail-closed on any mismatch.

Say hello

Never lose a silent sale again.

Put your checkout under watch in two minutes — or drop us a note. We like meeting store operators.
