PagerDuty alternative: on-call that doesn't price per seat

For teams without a dedicated security or SRE function, the practical PagerDuty alternative is a flat-priced tool that includes monitoring and paging. PagerDuty runs about $21 to $41 per user per month and routes alerts from monitoring you buy separately, so a five-person team is paying two bills before a single page fires. AlertKick charges a flat £39 or £149 a month regardless of headcount, generates the alerts itself, and covers rotations, overrides, and stepwise escalation. The honest trade-offs are no voice calls and a far smaller integration catalogue, both detailed below.

If you have landed here, one of two things happened. Either the renewal quote arrived and the per-seat maths stopped being funny, or you are setting up on-call for the first time, saw the pricing page, and wondered whether a five-person team really needs the tool that Fortune 500 SRE organisations run on. Both are fair questions. This post answers them honestly, including the parts where PagerDuty is the better choice.

Is there a cheaper PagerDuty alternative?

PagerDuty costs about $21 to $41 per user per month and only routes alerts from monitoring you buy separately. AlertKick charges a flat Free, £39 or £149 a month however many people are in the rotation, and includes the monitoring that generates the alerts. The trade-offs are no voice calls and a smaller integration catalogue, both covered below.

First, what PagerDuty actually is

PagerDuty is an incident response platform. It receives events, applies routing rules, consults an on-call schedule, pages the right person, escalates if nobody acknowledges, and gives you the analytics afterwards. It is genuinely very good at this. The escalation logic is battle-tested in a way that newer tools are not.

It is not a monitoring tool. PagerDuty does not check whether your server is up, watch your disk fill, notice a suspicious process, or tell you a certificate expires on Thursday. Something else has to detect the problem and hand it over.

That distinction is the whole story when you are stitching tools together. Adopting PagerDuty means you are buying the routing layer and still paying for the detection layer separately, whether that is a monitoring SaaS, a self-hosted Prometheus stack that somebody has to maintain, or both.

The pricing shape, not just the number

As of 2026, PagerDuty’s Professional plan runs about $21 per user per month billed annually, and Business about $41 per user per month. Month-to-month is more. Several things you might assume are included - analytics, status pages, live call routing, AIOps event intelligence - are add-ons priced on top of the seat cost.

The number matters less than the shape. Per-seat pricing means your on-call bill grows every time you hire, even though the alert volume, the number of servers, and the amount of work being done by the tool have not changed. For a 40-person engineering org that is a reasonable way to price. For a team of five where three people share the rotation, you are paying by headcount for something whose cost to serve is driven by infrastructure.

And it is the second bill that catches people out. The seat cost is the visible one. The monitoring underneath it - the SaaS subscription, or the engineer-hours keeping a DIY Prometheus and Alertmanager stack fed - is the one that quietly costs more. Setting up monitoring properly takes several tools, each needing its own code and config, and once it breaks you effectively need somebody whose job is managing the monitoring. That is not a good use of a five-person team.

When PagerDuty is the right answer

Switching to save money only to hit a gap at 3 AM is a bad trade. Check these conditions first:

• You need voice calls in the escalation chain. A phone that rings through Do Not Disturb is a real capability. If your escalation policy depends on it, the field narrows considerably.
• You have a large integration surface. PagerDuty has several hundred native integrations. If you need deep two-way sync with a specific ITSM or ticketing system, check that before anything else.
• You are at enterprise scale. Service dependency mapping, stakeholder communications, postmortem workflows, and advanced analytics across hundreds of services are things PagerDuty does properly. Most alternatives approximate these features.
• Compliance or procurement mandates it. Sometimes the answer is decided above your pay grade.

If two or more of those apply, stay. The rest of this post will not change your mind, and it should not.

Where AlertKick fits

AlertKick approaches the problem from the other end. It is the monitoring, with on-call and escalation built in.

On the on-call side you get standard rotation schedules: weekly, bi-weekly, or custom rotation schedules with multiple schedules for different teams and a roster per area of expertise. One-time overrides handle holidays and shift swaps without breaking the underlying rotation. Stepwise escalation chains keep climbing until somebody acknowledges. Each person configures how they want to be reached, and the Notify Person channel honours those preferences. A policy can say “tell whoever is on call” without hardcoding phone numbers.

Alerts land in email, Slack, Telegram, WhatsApp, SMS, mobile push, or any custom webhook. The escalation ladder is deliberately ordered least to most disruptive. Quiet channels fire first. SMS arrives on the third step. This prevents people from dreading the pager and muting it.

The difference is what generates the alert in the first place. The agent watches your hosts. Infrastructure monitoring and eBPF security detection are the same product and the same bill as the on-call rotation. There is no separate monitoring subscription to route from.

Pricing is flat, not per seat. Free covers 10 uptime monitors and heartbeats at 5-minute checks. Commercial use is explicitly allowed. Professional is £39 a month for 5 hosts with eBPF security included, 20 checks every minute, and 30-day retention. Business is £149 a month for 25 hosts, 100 checks, 90-day retention, and compliance evidence and reports. Adding a sixth person to the rotation costs nothing on any of them.

The honest limits

• No voice calls. Escalation ends at SMS. For teams that rely on text at 3 AM, this works. If you specifically need a robocall that overrides silent mode, AlertKick does not have it.
• A much smaller integration catalogue. Custom webhooks bridge most gaps, but “most” is doing work in that sentence. Check your specific tools.
• Less mature incident tooling. No service dependency graphs, no stakeholder communication workflows, no analytics suite of PagerDuty’s depth.
• It is a different shape, not a drop-in. If you already have monitoring you are happy with and want only the routing layer swapped, AlertKick is a bigger change than a like-for-like migration. Its value is in collapsing two tools into one, which only pays off if you were going to replace both.

Working out whether it is worth it

1. Add up what you currently pay for on-call and for the monitoring that feeds it. The second number is the one people forget, and if your monitoring is self-hosted, put a real hourly figure on the maintenance.
2. Write down your escalation policy as it actually runs today, not as documented. Note every channel it depends on.
3. Check that list against the limits above. Voice calls are the usual dealbreaker; find out early.
4. Start on the free tier - no card - and put one non-critical service on it alongside your existing setup. Build a rotation with two people and a real escalation chain.
5. Break something on purpose. Point a monitor at a dead port and let it escalate all the way through without acknowledging. Watch where each notification lands and how long each step takes. Trust nothing you have not seen page you.
6. Run both in parallel for a couple of weeks before you cancel anything.

If you are here because a vendor changed under you rather than because of price, the same evaluation applies to the Opsgenie shutdown in April 2027 and to Grafana OnCall being archived. Both migrations are worth doing deliberately rather than at the last minute.

And whichever tool you land on, what reduces 3 AM pages is cutting the alerts that should never have paged anyone in the first place.
