About
Built because the alternative is finding out on Thursday.
Plumbline is new, has no customers yet, and says so on its own marketing site. Here is what it is, who is behind it, and what stage it is honestly at.

The problem it was built for
An agency looks after somewhere between ten and a hundred client websites. Every one of them can break in a way nobody notices: a plugin updates itself overnight and blanks half a page, a certificate expires on a Sunday, a contact form stops delivering and looks perfectly fine while doing it.
Nobody can watch forty sites at once, so the way an agency usually finds out is a phone call from the client. That call costs reputation, costs unbillable emergency work, and costs a little of the trust that the retainer depends on.
There is plenty of monitoring software. Most of it was built for engineering teams watching their own infrastructure, which is a different job: one system, deep access, an on-call rota. An agency has forty systems, no access to any of them, and one person who is also doing the design work.
The two rules it is built around
Never alert on something that is not real. Monitoring tools do not get cancelled for missing a feature. They get cancelled because they cried wolf at 4am, got muted, and then missed the one that mattered. So a failure has to be seen twice before anyone is told, and a single bad result never wakes anyone.
Never report our own failure as the customer’s. If our worker times out or our browser crashes, that is our problem, recorded as ours, shown as ours, and excluded from what we tell your client. Conflating the two is how a monitoring tool quietly becomes a liar.
Everything else — publishing the price list, refusing to quote uptime percentages, storing the evidence behind every result, verifying ownership before the first check — follows from those two.
Who is behind it
Plumbline is operated by [LEGAL ENTITY NAME]. It is a small operation, not a company with a support department, and while that is true the person answering hello@plumbline-lb.com is the person who wrote the code.
That is worth knowing in both directions. You will get a straight, fast, technical answer. You will not get a 24-hour support desk, and you should price that into your decision.
What stage it is actually at
The product is built and tested. The checks, the incident engine, the alerting, the reports, the multi-tenant data layer and the deployment all exist and work. What it does not yet have is customers.
So the honest position is this: the code is ahead of the evidence. Every assumption on this site about what agencies need is an assumption until an agency has told us otherwise. That is exactly why the first ones are free, and why we would rather hear that you already use something and are happy with it than never ask.
If you look after client sites on a retainer, a twenty-minute conversation about how you currently find out one has broken is worth more to us than a sale.
