Dead links are eating your sales.

Radar404 watches your store, catches every 404 and sends visitors to the right page before they hit the back button, on autopilot.

Free plan included · 5-minute setup · No code

Every 404 is a customer walking out

Broken links never announce themselves. They pile up quietly, and each one sends your visitors, and Google, into a dead end.

01

Deleted & archived products

Their URLs keep receiving traffic from ads, emails and search long after the product is gone.

02

Renamed handles

Change one product handle and every old link to it breaks on the spot, everywhere it was ever shared.

03

Old backlinks

Blogs, newsletters and social posts keep sending visitors to pages that no longer exist. That equity is lost.

How it works

Three steps, zero maintenance.

1

Detect

A tiny beacon on your 404 page reports every broken URL in real time. It only loads on the 404 page, so your store stays just as fast.

2

Match

AI compares the broken URL to your actual catalog and finds the page your visitor was looking for, with a confidence score.

3

Redirect

Above your confidence threshold, the permanent redirect is created instantly. Below it, visitors go to your homepage and the fix waits for your one-click approval.

Everything you need to never lose a visitor again

Built for busy merchants: the work happens automatically and every action stays visible.

AI that knows your catalog

Suggestions come straight from your real catalog, never from made-up URLs. A typo like /bonnets-mohaiaaa lands on /bonnets-mohair.

/products/bonnets-mohaiaaa
/products/bonnets-mohair
92% confidence
0

visitors saved this month

Every redirect served is a visitor who stayed on your store instead of bouncing.

Delete a product, we cover for you

Archived or deleted products get a redirect automatically. Restore the product, the redirect is removed. Nothing to remember.

One rule, hundreds of fixes

Wildcard patterns with captures migrate whole URL families in one line.

/blog/* → /blogs/{1}

Everything logged

Every automatic action is recorded in the activity log. You can review it and undo it whenever you want.

Import & export

Shopify's native CSV format, both directions. Bulk actions included.

Frequently asked questions

Will it slow down my store?

No. The beacon is a few lines of script that only load on your 404 page. Your normal pages are untouched.

How does the AI pick the right page?

It compares the broken URL against your actual products and collections, then returns the closest match with a confidence score. It can only suggest pages that really exist on your store, so it never invents URLs.

What if the AI gets it wrong?

You set the confidence threshold. Below it, visitors are sent to your homepage and the suggestion waits for your one-click approval. Auto-accept is reserved for obvious typos of the same product, and every action is logged and reversible.

Do I need to touch my theme code?

No. Radar404 is a standard app embed: one toggle in your theme editor, which the app opens for you with a single click.

What happens if I uninstall?

The redirects Radar404 creates are native Shopify URL redirects, so they keep working even without the app. Your app data is deleted from our servers.

Give your store's ghosts somewhere to go.
