Better Stack alternative: uptime monitoring without the incident platform

What Better Stack does well

Better Stack is not really competing on uptime checks. It is competing as an incident management platform that happens to include monitoring, and on that ground it is strong.

• On-call schedules, escalation policies, and incident response workflows are first class, not bolted on.
• Alerting is unmetered in a way most competitors are not: phone calls, SMS, and push notifications without buying credit packs.
• Check coverage is broad, including Playwright-based browser transaction monitoring, which genuinely reproduces a multi-step user journey rather than fetching one URL.
• A Terraform provider alongside the REST API, which matters if your infrastructure is defined in code and monitoring should be too.
• The status pages are polished and the product is clearly well designed throughout.
• The free plan covers ten monitors at three minute intervals, which is a faster free interval than most.
• It sits inside a wider observability suite, so logs and metrics can live next to your uptime data.

If you have a rota, a formal escalation policy, and someone who is paged at 4am, that combination is worth paying for and Undownable does not replace it.

Where it starts to hurt

The billing model is the usual reason people go looking. Ordinary team members are not a separate charge, which is good, but the on-call responder role is billed per seat and it is not a small number: roughly the cost of several months of Undownable Pro, per responder, per month. Add a second and third responder and the monitoring line item on your invoice stops being a rounding error.

Monitor capacity is bought in blocks on top of the base allotment, and additional status pages are priced separately again. None of that is unreasonable for a platform of that scope, but it is a lot of machinery if what you actually needed was "tell me when the site is down and show my customers a status page".

Side by side

Where Undownable differs

Undownable is deliberately narrower. It does uptime monitoring, alerting, and status pages, and it does not try to be your incident command centre.

• One flat price per team, full stop. No responder seats, no monitor blocks, no per-status-page fee. What you pay in month one is what you pay when the team doubles.
• Unlimited status pages on Pro, each with its own custom domain, rather than paying per page.
• Every alert channel on every plan including free, with first class ntfy support for self-hosted ntfy servers with access tokens.
• Exactly-once delivery, flap suppression, and confirmation thresholds so a single blip never pages anyone.
• A degraded state distinct from down, used for things like a certificate nearing expiry, so warnings do not count against your uptime figure.
• SSL checks that validate the full chain and hostname with escalating warnings at 30, 14, 7, and 1 days out.
• Push heartbeats for cron jobs and self-hosted monitoring boxes, in the same account and on the same alert routing as everything else.
• A first-party MCP server, so an AI agent can create monitors, read status, and open maintenance windows with a scoped token.
• Maintenance windows you can open and close from a deploy script, so a planned reboot does not page the team.

Who should stick with Better Stack

• You run a real on-call rotation with schedules, escalation policies, and acknowledgement tracking. That is their core competence and Undownable has no equivalent.
• You need phone call or SMS escalation. Undownable does not send either.
• You need browser transaction monitoring that walks through a multi-step flow such as login and checkout. Undownable checks endpoints, not journeys.
• You want monitoring defined in Terraform alongside the rest of your infrastructure.
• You already use their logs or metrics products and want one vendor and one pane of glass.
• You need sub-minute check intervals.

One genuinely good hybrid: keep Better Stack for the on-call platform, and run a couple of free Undownable checks as an independent second opinion on your most critical endpoint. Two vendors failing at once is a much rarer event than one.
