Failures confirmed before you are woken up, not on the first blip
A clear pane into your environment
Uptime, SSL certificate, DNS and blacklist monitoring with status pages, on-call rotation and a workspace per client — plus error tracking that speaks your existing Sentry SDK. When something upstream breaks, you get one incident showing the blast radius — not forty emails.
20 monitors and 5 blacklist checks on the free plan. No card, no expiry, and usable commercially.
One incident, not forty
Monitors declare what they depend on. When the database host goes down, the twelve services behind it are shown as blast radius on a single incident instead of paging you twelve times.
A workspace per client
Give a client their own login that sees their monitors, their status page and nothing else — not your other clients, not your own infrastructure. Billed to you, invisible to them.
Blacklist monitoring, free
Your mail server IPs checked against 100+ DNSBLs, from the free plan up. Find out you are listed before your customers tell you their invoices are not arriving.
White-label status pages at $19
Custom domain, your logo, your CSS, no mention of us. The nearest comparable plan elsewhere is an order of magnitude more.
On-call that is included
Rotations, overrides and escalation policies from the $19 plan, rather than per responder per month.
Errors, through your existing SDK
Point any Sentry SDK at us by changing one line of config and see what your application is actually throwing, grouped so ten thousand events read as one bug. Uptime says the host answered; this says whether it works.
Told where you already are
Email, Slack, Teams, Discord, Telegram, webhooks, PagerDuty, Jira Service Management, and SMS or a phone call through your own Twilio account. Pick which channels are routine and which are escalation, per monitor.
Inside the machine, not just the port
One command installs an agent that reports CPU, memory and disk from the host itself. A server answering on 443 with a full disk is not up, and a port check will never tell you that.
Mail servers that actually speak
SMTP, IMAP and POP3 checked by holding the conversation — capabilities, STARTTLS, certificate — not by seeing whether the port opens. Half a broken mail server still accepts connections.
Pricing
Flat monthly tiers. No per-check metering and no overage bills — if you exceed a limit, the next thing you create is refused, not charged for. Annual is ten months for twelve.
