SitesRadar watches every site you ship — broken links, SSL expiry, downtime, email deliverability, and HTTP errors — and pings you the moment something regresses. Across all your clients, on a schedule, automatically.
Built for freelancers and small agencies: per-client, plain-English, and priced for small teams.

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.
Three steps to turn "I hope everything's fine" into "I'd know within minutes if it wasn't."
Paste in a URL — or ten. Each client site goes on the radar in seconds. No agents, no DNS changes, no code to install.
SitesRadar sweeps every site around the clock — links, certs, status codes, email authentication, and redirects — and remembers what "healthy" looked like last time.
The moment something regresses, you get an email with exactly what changed and where — before the page is even cold.
acme-client.example: MX records changed
We re-checked before sending this. It's real.
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 most monitors don't look at. Caught before they reach the person paying you.
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.
5xx errors, timeouts, redirect loops, a whole site going dark. We notice within minutes of the status code going wrong, not next business day.
A red lock warning scares customers off, and a lapsed domain takes the whole site with it. We count down both, reading the public registry (RDAP) for the domain, and warn you with days to spare.
An MX record drifts and mail stops flowing. A nameserver flips during a migration. We snapshot your records and alert the moment any of them move, so a quiet edit doesn't quietly break email.
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.
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.
noindex after CMS updateThe 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. Most uptime monitors don't look inside files. We do.
C:\Users\jsmith\Desktop\…The name is the point: a freelancer or small agency doesn't watch a site — you watch a dozen, each one someone else's livelihood. SitesRadar puts them all on a single screen.
