SiteAirbag never reads what your visitors type, never records their screens, and never follows them around the web. It only watches whether the one action you chose worked.
- Field contents never read
- Keystrokes never captured
- No session replay
Is SiteAirbag for you?
- People fill in a form, booking or checkout on your site most days.
- One missed enquiry costs you more than $29.
- You'd rather know now than on Friday.
- Fewer than ~20 enquiries a week. SiteAirbag learns your normal from 20 real completions; below that it still catches hard failures, but your trial will end before you see it learn. Save your money for now.

Why I built SiteAirbag
A while ago I needed a quote from a business. I filled in their form, pressed send — and got an error. So I did what anyone does: I left, found a competitor, and got my quote there.
Their form was working again an hour or two later. Their alerts probably told them. But I was already gone, and I doubt I was the only one.
That gap, between broken and fixed, is what SiteAirbag is for. Not another alert: a second way in, the moment something fails.

Questions
Will it slow or break my site?
No. The script loads in the background and fails open: it never blocks a click, cancels a form or changes a response. If SiteAirbag is slow or down, your site behaves as if it were never installed.
Do you read what visitors type?
SiteAirbag never reads what your visitors type, never records their screens, and never follows them around the web. It only watches whether the one action you chose worked.
What if I get few enquiries?
SiteAirbag learns your normal from 20 real completions. Before that it still catches hard failures, like a server error, once a visitor retries. With fewer than about 20 a week, your trial will end before it learns.
What happens after the trial?
If you don't cancel, your plan starts when the 7 days end: Starter is $29 a month. We email you before the first charge. Cancel anytime from your billing portal.
Do I need a developer?
No. You paste one line into your site's header, where analytics tags go. Our compatibility guide shows where that is on WordPress, Wix, Squarespace, Webflow and more.
What can't it see?
It sees what happens in your visitor's browser. It can't see what happens after your server accepts a form, like an email landing in spam. See the full list.
