Best Website Monitoring Software for Agencies and MSPs

For an agency or MSP running ten client sites with a white-labeled status page each, the same job costs $78 a month on Site24x7's MSP plan, $99 a month on Uptimehub Business, and $2,762 a month on Better Stack. The monitors are almost free in every case. What separates those numbers is how each vendor prices the three things that only agencies buy: a status page per client, a seat per person who can be paged, and a tenant boundary between clients. Pick on those three lines, not on the monitor count.

Every uptime tool will happily check forty URLs. That part of the market has been commoditized for a decade and the price of a check has fallen to roughly nothing. If you run monitoring for your own product, you can pick almost any vendor on price and be fine.

Agencies and managed service providers are buying a different product, and most vendor pricing pages are not organized around it. You need a page your client can look at during an incident, with your logo on it and not the vendor's. You need your account managers to receive alerts without paying a seat fee for each one. And you need the boundary between client A and client B to be real, so nobody sees the wrong dashboard. Those three requirements are where agency monitoring bills are actually made, and they can differ by a factor of thirty across vendors who all look similar on the monitor line.

The scenario, and what four vendors charge for it

Take a concrete brief, because generic comparisons hide exactly the costs that matter here. Ten client websites. Forty monitors in total, since most clients need the marketing site, an API endpoint, a checkout path and a certificate watched. Ten status pages, one per client, each carrying the client's branding rather than the monitoring vendor's. Three people at the agency who can be paged.

Read the Better Stack row again, because it is not a typo and it is not a criticism of the product, which is genuinely good. Better Stack sells white labeling as a $250 per month per page add-on. Ten client pages is $2,500 a month, or $30,000 a year, for the single feature of removing someone else's logo. An extra status page without white labeling is $15, so the branding costs about seventeen times what the page itself costs. If your clients will accept a page that says Better Stack on it, your bill drops to $262. If they will not, and most agencies find they will not, the same account is ten times the price. We break the full add-on list down on Better Stack pricing.

The Site24x7 row is the one that surprises people, and we are going to say plainly that they win this particular brief on price. Their MSP plan is built for exactly this shape of customer: $59 a month covers nine client tenants with real separation, and additional clients are $10 each. That is $21 a month less than we charge, and if price is your only criterion you should buy theirs. The catch is not the base fee, it is the bundle: fifteen websites across nine clients is under two per client, and everything past it comes off an add-on rate card with six separate meters on it. We mapped all of them on Site24x7 pricing, including the part where their website plans get you fewer monitoring locations as the price goes up.

The three lines that actually decide an agency bill

Status page branding, priced per page or included

This is the single largest variable in agency monitoring pricing, and it is the one buried deepest in the pricing pages. Vendors take one of three positions: white labeling is included, it is gated behind the top tier, or it is a per-page add-on. The third is the expensive one and it scales with your client list rather than your infrastructure, which is backwards for how agencies grow. Before you shortlist anything, find the white-label line and multiply it by your client count. If a vendor does not publish that number, that is your answer for the moment. We keep a running comparison of who bundles it on status page software.

Seats, which agencies have more of than anyone

Agencies have account managers, a support desk, developers and often the client's own technical contact, and all of them have some reason to see an alert. Per-seat pricing punishes exactly that structure. Better Stack charges $34 a month per responder, so a five person on-call rotation is $170 before a single monitor. Site24x7 does not charge per user at all, which is a real advantage of theirs worth naming, and neither do we. If a vendor prices by seat, count your seats honestly, including the people you would add if it were free, because that is the team you actually want receiving alerts.

Multi-tenancy, which is not the same as multiple status pages

Running ten status pages is not the same as running ten tenants. A tenant means the client's data, contacts and dashboards are separated, so an account manager can be given access to one client without seeing the rest of your book. Site24x7's MSP line and our Business plan both do this. Several otherwise strong tools do not, and the workaround is separate accounts with separate bills, which quietly doubles the admin and removes any volume pricing you had. Ask for a demo of the permission model specifically, not the dashboard.

What to check before you sign

Four questions get you most of the way, and all four are answerable in an hour.

What does the bill look like at twenty clients? Not ten. Agencies churn upward, and the vendors that look cheapest at your current size are often the ones with the steepest per-client line. Take whatever number you land on and double the client count, then look again. A flat plan that covers 400 monitors does not change at all; a per-page or per-client model roughly doubles.

How many locations does the check actually run from? A client in Chicago whose site is unreachable from Frankfurt has a real problem, and a single-location checker will not see it. Confirm the number of probe regions and whether it is gated by plan, because at least one vendor gives you more locations on the cheap plan than the expensive one.

Can you retry before paging? Agencies suffer more than anyone from false alarms, because a false page at 3am costs you a person's morning and, eventually, their trust in the alerts. Automatic retry from a second location before an alert fires is the single most useful feature on this list and it is not always on by default.

What happens to the status page when your monitoring goes down? Ask where the status page is hosted relative to the monitoring infrastructure. A status page that shares a failure domain with the thing it reports on is decoration.

Where each of these tools is the right answer

The honest summary is that this is not a single market and there is no single winner.

Site24x7 MSP is the best value if your clients need more than uptime. It monitors servers, applications, network devices and logs, none of which we do, and at $59 a month for nine tenants that breadth is not available anywhere else at that price. Buy it if you manage infrastructure, not just websites, and budget carefully for the add-on rate card.

Better Stack makes the best-looking status pages in this comparison and its incident management is stronger than ours. If you have a handful of clients and they will accept vendor branding, or you have one flagship client where $250 a month for a perfect page is justified, it is a good buy. At ten branded pages the arithmetic stops working.

Uptimehub Business is the right answer if your clients are websites and APIs rather than server estates, and every one of them needs a page with their own logo on it. Ten white-labeled client pages, 400 monitors from six regions, and unlimited seats for your team and theirs, at $99 a month flat. We do not run an agent, collect CPU metrics or ingest logs, and if you need those we have pointed you at who does.

One more thing worth planning for while you are here. Agencies that add monitoring to a retainer usually price it as a recurring line item, which turns a technical decision into a billing one, and the failure mode is not the monitoring at all: it is the invoices. If you are adding a monthly line to ten client agreements, it is worth having something that will chase the unpaid ones automatically before you have thirty of them to reconcile by hand.

Common questions

What is the best uptime monitoring tool for an agency?

It depends on whether your clients need infrastructure monitoring. For website and API uptime with a branded status page per client, a flat plan that includes white labeling wins on both price and admin, because per-page branding fees scale with your client list. For agencies managing servers, networks and applications, Site24x7's MSP plan at $59 a month for nine tenants covers a much wider surface than any pure uptime tool.

How much should an agency pay for website monitoring?

Between $78 and $100 a month for ten clients is the realistic range in 2026 if you choose a vendor whose pricing model fits an agency. The same requirements can cost over $2,700 a month on a vendor that bills white labeling per page, which is why the model matters far more than the headline price. Our full breakdown by vendor is on the uptime monitoring pricing comparison.

Do clients need their own status page?

They need one during an incident, and the value is almost entirely in the hour when their site is down and their staff are calling you. A public page with the client's branding absorbs those calls and gives your team room to fix the problem. Outside an incident it is quiet, which is why it is easy to under-value when you are choosing a vendor and impossible to do without at 9am on a bad Monday.

Is white-label status page branding worth paying for?

For an agency, yes, but almost never at a per-page rate. Your client is paying you to be their technical team, and a page carrying a third-party monitoring vendor's logo undermines that on the one day it is being read. The question is not whether to have it, it is whether to buy it from someone who charges per page. At $250 per page per month, ten clients is $30,000 a year for a logo.

Can you monitor client sites without giving clients access to everything?

Only with real multi-tenancy, which is a different feature from having multiple status pages. Check whether you can scope a user to one client, and whether client-facing users can be invited without consuming a paid seat. If the answer to either is no, the practical workaround is one account per client, which multiplies your admin and usually your bill.

How many monitors does an agency need per client?

Four is a common baseline: the marketing site, one critical API or checkout path, the SSL certificate, and a DNS or domain expiry check. Ten clients therefore lands around forty monitors, which is comfortably inside most mid-tier plans. The count grows with staging environments and client-specific integrations rather than with client numbers, so estimate from the complexity of your largest client rather than averaging.
