Short answer, for the common agency scenario — 20 clients, ~100 monitored endpoints, one branded status page per client: UptimeRobot Team is the cheapest that fits at $34/mo, then a big jump to Site24x7 MSP (~$248/mo), Better Stack (~$335/mo), and Atlassian Statuspage (~$580/mo, monitoring not included). Uptime Kuma is $0 but can’t give clients their own logins. The prices below were checked against each vendor’s own pricing page in July 2026.
Most “uptime monitoring pricing” comparisons price a single team with 50–1,000 monitors. That’s the wrong scenario for an agency. An agency’s cost is driven by two things those comparisons ignore: how many separate status pages you need (one per client) and whether you’re billed per monitor or per client. Here’s the real math.
The scenario, priced identically for every tool
- 20 client businesses
- ~5 monitored endpoints each = ~100 monitors
- 20 separate branded status pages, one per client, each showing only that client’s services
- Frequent checks (1-minute baseline)
The numbers (verified July 2026)
| Tool | Monthly cost | 20 scoped status pages? | Bills per | Source |
|---|---|---|---|---|
| Uptime Kuma (self-host) | $0 + ~$5–20 VPS | Yes, unlimited | — (free) | Single-user, no RBAC |
| UptimeRobot Team | $34 ($29 annual) | Yes, 100 included | monitor | pricing |
| Site24x7 MSP | ~$248 (MSP Enterprise ~$428 for 20 pages) | 10 included / 20 on Enterprise | customer | MSP pricing |
| Better Stack | ~$335 ($270 annual) | Yes, 1 free + $15/page | monitor + page | pricing |
| Atlassian Statuspage | ~$580 (pages only, no monitoring) | Yes | page | pricing |
| Pingdom | Not published | Unknown | monitor | Pricing page not publicly accessible |
| Uptime.com | Not published | Appears capped ~4 pages | monitor | Pricing gated behind a calculator |
A few tools genuinely couldn’t be priced: Pingdom returns a 403 to anyone who isn’t a logged-in buyer, and Uptime.com hides its tiers behind a JS calculator. “Won’t show you a price” is itself a useful fact when you’re comparing.
Why the spread is so wide
Same job, prices from $34 to $580. The difference is the billing model:
- UptimeRobot bills per monitor and throws in 100 status pages on the Team plan, so 20 pages costs nothing extra. That’s why it’s an order of magnitude cheaper than the rest for this scenario.
- Better Stack bills per status page ($15/mo each). 19 extra pages is $285/mo — 85% of the bill is status pages, not monitoring.
- Atlassian Statuspage bills per page too, and does no monitoring at all. You’re paying ~$580 for the page layer on top of whatever monitoring vendor you use.
- Site24x7 MSP is the only one that bills per client ($9 per extra customer) — which is how agencies actually think, but it’s built for larger MSPs and priced accordingly.
The catch nobody puts in the pricing table: per-client logins
Cost isn’t the whole story, and the cheapest option hides a limitation. A branded status page is not the same as a client login.
- UptimeRobot and Better Stack let you password-protect a status page. That’s a shared password, not an account. You can’t give one client access without giving it to whoever has the password, you can’t revoke one client, and there’s no record of who viewed it.
- Uptime Kuma can’t give a client any login at all — it’s single-user with no RBAC.
- Only Atlassian Statuspage (real per-viewer auth) and Site24x7 MSP (RBAC per customer) treat “this client sees only their own stuff, with their own account” as a first-class feature — and they’re the two most expensive options.
So the honest summary: if you just need cheap monitoring with public per-client pages, UptimeRobot at $34/mo is the answer and it’s not close. If you need each client to have their own authenticated login, your options narrow to the expensive end — or an open-source tool that models per-client access, like Warden, which ships a client-only role and can be self-hosted free.
Bottom line
- Cheapest that fits the 20-client scenario: UptimeRobot Team, $34/mo.
- The price swings 17× based purely on whether the tool bills per monitor, per page, or per client.
- Per-client logins are the real dividing line, and the cheap tools don’t have them — they have shared page passwords.
- Price the scenario you actually have (clients × pages), not the generic “how many monitors” number every comparison uses.
