For saas and online stores
You deploy often. Know within the minute whether checkout still holds.
A SaaS or a store lives on three pages: pricing, login, checkout. PostShip replays them on every release, like a customer, and warns you on your phone before the first one writes in.
What happens, with nothing
The Stripe script no longer loads, the page answers 200
An update removes the tag, the checkout stays pretty and empty.
A staging noindex ships to production
Nothing breaks on screen.
Yesterday's JS bundle is still served by the CDN
The page loads, no button responds.
What PostShip does for you
The pages that sell, checked on every deploy
Pricing, login, checkout: status, displayed price, button, payment script, in one go — at T+0, T+2 and T+8 minutes after release.
How it worksThe checkout funnel replayed in order
Home, pricing, checkout, like a customer, stopped at the first broken step.
How it worksRollback, by hand or on its own
A deploy that breaks a page that sells goes back to the previous one verified good — in one gesture from Deployments, or without you if you ask.
How it worksAlerted on your phone, once
A notification, with no Slack or email between the failure and you; one message per incident, nothing while all is well.
How it works
What we're often asked
I already have UptimeRobot.
Keep it: it sees the server go down before we do. PostShip looks at what it doesn't — the page, its assets, the payment, the second you deploy. The two don't step on each other.
I deploy on Vercel, isn't that enough to know it's live?
Vercel knows the build passed. It doesn't know the domain serves the new build, nor that the payment script is still there. That's exactly the gap PostShip fills.
What if I only deploy once a week?
The free plan checks 5 URLs every 15 minutes and on every deploy, no card. Start there; the plan comes when the checkout funnel deserves it.
