About Cartainty
Cartainty runs the checkout flows you set up for each store on a schedule, in a real browser, and tells you which step failed, with a screenshot of every step. It exists for a simple reason: checkouts break quietly, after a theme update, an app install or a settings change, and the first person to notice is usually a customer who couldn't pay.
Who it's for
Agencies that look after many client stores, and store teams who would rather hear about a broken checkout from a test than from a customer. One workspace holds every store, and a client-ready report shows what was checked and what failed.
What it does
- Replays a checkout flow you record or build: product page, cart, discount, shipping, up to the payment step.
- Runs it on a schedule (weekly, daily or hourly, depending on the plan) or when you press Run.
- When a scheduled check fails quickly, re-runs it once to rule out a blip before alerting you by email (Slack and webhooks on higher plans).
- Also checks that the scripts, pixels and cookie banner you expect are still on the page.
What it deliberately doesn't do
- It doesn't submit payment, so it doesn't prove a payment can be authorized.
- It runs in Chromium. Mobile and tablet are emulated screens, not real devices or Safari.
- Each test runs one viewport; covering desktop and mobile takes two tests.
- Pixel checks confirm a script is present, not that its events fire.
- It isn't SOC 2 certified.
We would rather you know the limits before you rely on it than find them after.
