A client's server stops responding. You find out at 9:12, in an email that opens with “is the site down for you too?”.
Client website monitoring · Web agencies & freelancers
Monitoring for your clients' websites.
Hear about trouble at the first real sign, stay ahead of SSL expiry, and show the value of the maintenance you already bill for.

Incident
What happens today
Three situations you already know.
An SSL certificate expired overnight. The browser shows a red security warning on your client's shop. Mid-sale.
“Has my site been up this month?” You've billed maintenance for two years, and you've got no figure to answer with.
What changes
You open the dashboard. It's all there.
01
You hear about it first
Every site checked continuously. An alert goes out at the first sign of a real incident — not at the first network hiccup. You've got time to act before the call.
02
Certificates stop catching you out
SSL expiry flagged 30, 14, 7 and 3 days ahead. For every domain across your whole portfolio, without thinking about it.
03
You have the numbers
Uptime over 24 hours, 7 days, 30 days. Per site, per client. Enough to answer — and enough to justify what you charge.

The difference
A tool that wins you clients, not just one more insurance policy.
Other monitoring tools sell you a safety net: a line item you hope never pays out. That's useful. It isn't enough.
White-label
Reports under your brand
Produce a monthly uptime report — and a traffic one, if you turn it on — in your agency's colours, to show what your maintenance contract is worth. Your logo, your colours, your name. A link you share yourself, and can revoke whenever you want.

Scope
What it doesn't do.
- No APM, no distributed tracing, no application logs
- No server CPU or RAM monitoring
- No Kubernetes, no orchestration
- No dashboard that takes two days to configure
- No nested pricing with forty options
If you want a full observability platform, there are excellent ones. That's not what I'm building. I'm building the tool I wanted back when I ran sites for clients. See how to organise website monitoring for a web agency.
Hosted in the EU
Servers and data in Europe. No transfer outside the EU, no grey area to explain to your own client.
Support in English
From the person who writes the code. No support centre, no ticket crossing three time zones.
No lock-in
Cancel in one click from the dashboard, no notice period. Account deletion is immediate and permanent, whenever you ask.
What it will cost
You pay per client you look after. Not per URL.
Counting URLs makes no sense: a client is a site, plus its domain, its certificate, its shop and its contact page. You manage clients, not rows in a spreadsheet.

Frequently asked
Before you hand your sites to the tower.
Which sites can I monitor?
Any site reachable on the web: brochure site, shop, application or API. You group sites by client to follow your portfolio without juggling dashboards.
How are incidents detected?
Watchtower Ping checks each site regularly and emails you once an incident is confirmed, so a passing network glitch never wakes you up.
What does SSL monitoring cover?
Every domain's certificate is checked, and its expiry is flagged to you 30, 14, 7 and then 3 days ahead.
Can I show the results to my clients?
Yes. Monthly uptime reports can carry your agency's name, logo and colours. You choose when to share them, and you can revoke the link at any time.
Does the trial need a card?
No. The trial runs 14 days with no card. You can then pick a plan or stop, from the dashboard.
