The status quo
Right now, your clients are your monitoring system.
You deploy a fix on Friday, the weekend passes, and the first you hear of the 500 error is an email titled "is the site down??" on Monday. The work was fine. The silence wasn't.
- Manual spot-checks don't scaleOpening 12 client sites every morning to eyeball them isn't monitoring — it's a chore you'll skip the day it matters.
- A deploy at 11pm breaks something at 11:05SSL lapses, a redirect loops, an image 404s after a CMS update — small things that quietly cost your client conversions.
- Finding out last makes you look carelessIt's not that something broke — things break. It's that they noticed before you did. That's the part that erodes trust.
- Watch 10+ sites without lifting a finger. Add every client once; the morning spot-check ritual disappears.
- One status view, sorted by what needs you. Healthy sites stay quiet; anything slipping floats to the top.
- Look like the agency that's always on it. Reach out about the problem before your client has even noticed it.

How it works
Set it once. Hear from it only when it matters.
Three steps to turn "I hope everything's fine" into "I'd know within minutes if it wasn't."
STEP 01
Add your sites
Paste in a URL — or ten. Each client site goes on the radar in seconds. No agents, no DNS changes, no code to install.
STEP 02
We watch them on a schedule
SitesRadar sweeps every site around the clock — links, certs, status codes, email authentication, and redirects — and remembers what "healthy" looked like last time.
STEP 03
You get an instant alert
The moment something regresses, you get an email with exactly what changed and where — before the page is even cold.
No noise. We only ping you when something gets worse than the last good check — not a firehose of "still up" emails. A clean site stays silent.
What it catches
Every one of these is a client email you didn't have to get.
The boring failures that quietly make you look bad — uptime and SSL, yes, but also email landing in spam, domain expiry, silent DNS changes, SEO regressions, and leaked file metadata that other monitors don't even look at. Caught on the edge, before they reach the person paying you.
Near-miss caught
Broken links
A deploy renames a route, a PDF gets deleted, an external link rots. We crawl and flag the dead ones before a visitor hits them.
→ caught: /pricing-2024.pdf now returns 404
Near-miss caught
SSL & cert expiry
The lock icon turning into a red warning is the fastest way to scare a customer off. We count down to expiry and warn you with days to spare.
→ caught: cert expires in 6 days, auto-renew failed
Near-miss caught
Uptime & errors
5xx errors, timeouts, redirect loops, a whole site going dark. We notice within minutes of the status code going wrong — not next business day.
→ caught: homepage returning 503 for 4 minutes
Near-miss caught
Redirect problems
A homepage loop, a missing HTTPS upgrade, or a redirect chain that never lands. We flag the routing problems that keep visitors from reaching the page.
→ caught: homepage redirect loop after deploy
Near-miss caught
Domain expiry
The one renewal nobody notices until the whole site vanishes. We read the public registry (RDAP) and count down the days, so a lapsed domain never takes your client offline first.
→ caught: domain expires in 19 days, auto-renew off
Near-miss caught
Silent DNS changes
An MX record drifts and mail stops flowing. A nameserver flips during a migration. DNS changes are silent and easy to miss — we snapshot your records and alert the moment any of them move, so a quiet edit doesn't quietly break email.
→ caught: MX records changed — mail now routes elsewhere
Included on Free
Email landing in spam
An SPF, DMARC or DKIM record can go invalid without anyone noticing — and a domain or mail host can land on a blacklist. Monitor one site free forever so quotes and receipts do not quietly miss the inbox.
→ caught: DMARC policy changed and mail host was blacklisted
Near-miss caught
Silent SEO regressions
A stray `noindex` after a staging push tells Google to drop the site from search — invisibly. We read the homepage's title, description, canonical and social tags and flag the ones that quietly cost rankings.
→ caught: homepage went `noindex` after CMS update
Nobody else does this
Leaked file metadata
The PDFs, images and Office docs on your client's site carry hidden metadata — author names, internal file paths, editing software, even GPS coordinates. We fetch what the site links to and read it back, so a private detail your client never meant to publish doesn't sit there in plain sight. Uptime monitors don't look inside files. We do.
→ caught: brochure.pdf exposes `C:\Users\jsmith\Desktop\…`

Built for a client roster
One radar for every site you're responsible for.
