PagerDuty alternative for a Slack on-call rota: when you only need to know who is on call

Many small teams open PagerDuty to answer one question: who is on call this week? If you also need alerts that wake someone up, PagerDuty is the right tool and Dutyroll is not an alternative. If you only need a fair rotation and a clear hand-over in Slack, you may be paying for far more than you use. Prices below are from PagerDuty's own pricing page, checked 2 November 2026.

What PagerDuty costs on its own page

	PagerDuty	Dutyroll
Free plan	Up to 5 users, 1 on-call schedule, 1 escalation policy, 100 SMS or phone notifications a month	1 rotation, any number of people
Next paid step	PagerDuty Professional: $25 per user per month ($21 on the annual plan)	Pro, $9 per workspace per month (or $90 a year)
Example: 8 people, several rotations, monthly billing	PagerDuty: 8 x $25 = $200 a month	$9 a month
Pages or calls a person	Yes: push, SMS and phone, escalation policies	No: posts in a Slack channel
Incident tools (alerts, post-incident reviews, status pages)	Yes	No

PagerDuty also sells platform plans from $2,800 a year. The example row is plain arithmetic on the listed monthly price; your PagerDuty bill may differ with add-ons or a negotiated contract.

Where PagerDuty wins

Alerting. If a monitoring alert must reach a human in minutes, at night, by phone, with a backup after five minutes of silence, you need escalation policies. Dutyroll has none.
Incident response. Incident channels, post-incident reviews and 750+ integrations are the product. Dutyroll does none of it.
Size. For a large engineering organisation, PagerDuty's reports and controls are worth the price.

Where a rotation app is enough

Support, triage, standup host, release captain or office-duty rotations that nobody pages at 3 a.m.
An on-call week that is a visible hand-over: the channel says who is on duty now and who is next, and anyone can see a skip or a swap.
A team past the 5-user free plan that does not want to pay per seat for a schedule.

Use both

Nothing stops a team from keeping PagerDuty for paging and posting the weekly hand-over in Slack with Dutyroll. Dutyroll does not sync with PagerDuty, so you enter the people once in each place. That double entry is a real cost; if you want one source of truth, pick one tool.

What Dutyroll does

You type /dutyroll new in a channel, enter the people in order and pick weekly, every weekday, every 2 weeks or monthly. Each hand-over post names who is on duty and who is next, with Skip and Swap with next buttons. Mark someone away and the rotation passes them over.

On call this week: @sam. Next: @priya.
[Skip] [Swap with next]

Add to Slack Free for one rotation. Pro is $9/month per workspace.

Next, Slack asks you to sign in to your workspace, then shows Dutyroll's 4 permissions before you press Allow: add the /dutyroll command, post messages, post in public channels without an invite, and see the member list (names, time zones). Dutyroll never reads messages. Not in the Slack Marketplace yet: Slack lists apps only after 10 workspaces use them. Free plan: 1 rotation, no card.

Set it up in two minutes

Add Dutyroll to Slack (the workspace admin may need to approve it).
In the channel where the hand-over should appear, type /dutyroll new.
Fill in the form: the duty's name, the people in order, the channel, weekly (pick the day), every weekday, every 2 weeks or monthly (pick the day of the month or the last Friday, say), and the time. The time is in your Slack time zone.
Dutyroll posts an announcement now, and the hand-over at the time you chose: who is on duty and who is next, with Skip and Swap with next buttons.

What Dutyroll does not do

It does not page or call anyone and has no escalation; it posts a message in a channel. If you need phone or SMS alerts, use a paging tool and keep Dutyroll (or not) for the visible weekly hand-over.
It does not sync with PagerDuty, Opsgenie or calendars (it can publish the rota as a read-only calendar link, see /dutyroll calendar), and does not update a Slack user group (@oncall) yet.
Cadences are weekly (one day), every weekday (Mon-Fri), every 2 weeks or monthly (a day of the month, or the last Friday, say, of it). No custom shift lengths. Away dates are entered in Dutyroll (Mark away, and the hand-over skips that person); there is no sync of away dates from a calendar or HR tool.
It is new (October 2026) and not yet in the Slack Marketplace; you install it from this site.
