Slack apps for incident management compared on price and on-call paging

What a Slack incident app has to do on the night of a SEV1

Every app on this list can create a channel. That is the easy part. The differences show up at 3 a.m., when the alert fires and nobody is looking at Slack.

• Paging that wakes a person. A Slack notification does not wake anyone. You need an on-call schedule, an escalation policy and push, SMS or voice calls. Some apps include this, some sell it as a second product.
• One command to declare. /incident (or the vendor's version) should open the channel, invite the on-call responder, set severity and start the timeline in one step.
• Roles. Incident commander, comms lead and scribe assigned in the channel, so the person fixing the problem is not also writing customer updates.
• Status page from the same incident. If the status page is a separate tool, someone has to copy updates across during the outage, and usually forgets.
• A postmortem that writes itself from the timeline. Every message, role change and status update with timestamps, ready for review the next morning.
• Viewers who do not cost a seat. Support, sales and managers need to follow incidents without being billed as responders.

If your team has no monitoring that fires the alert in the first place, that comes first. An uptime monitoring service that checks your sites and APIs every 30 seconds is the usual starting point, and every app below takes its alerts by webhook or email.

Slack incident management apps side by side

Prices are list prices per user per month, billed annually, from each vendor's public pricing page. Vendors change packaging, so confirm before you sign.

Opsgenie also has a Slack app that opens a channel per alert, but Atlassian stopped selling Opsgenie on June 4, 2025 and switches it off on April 5, 2027, so it is not a choice for a new purchase. Teams moving off it can read our Opsgenie alternative migration plan.

What a 15-person on-call rotation pays per month

The seat price on a pricing page is rarely the bill. The table below prices the same need for each app: 15 responders on call, Slack incident channels, paging by phone and a public status page.

Read it honestly. Zenduty without the status page add-on is the cheapest at 240 USD a month if you can live with a separate status page tool. FireHydrant's free plan covers up to 10 responders if you can do without on-call scheduling. IncidentBot Starter caps you at 3 schedules and 3 escalation policies and does not include incident roles. Teams that need roles or more rotations move to Team at 49 USD, where schedules, policies and SMS and voice paging are unlimited under fair use and you get 3 public or private status pages. At that tier incident.io and Rootly cost less per seat if you only compare list prices, so weigh what is included, such as free viewers and private pages. The seat calculator on our pricing page gives your exact figure.

Which Slack incident app fits which team

• Under 10 engineers, no formal rotation yet: FireHydrant Free or Zenduty Starter keep the bill near zero while you set up the process. Expect to move when you need phone paging or more than 5 users on Zenduty.
• 10 to 50 engineers, one rotation per team, everything runs in Slack: this is where a single product with paging, channels, roles and the status page in one seat price saves the most, because the alternative is two subscriptions and copying updates between them. incident.io, Rootly and IncidentBot all target this group. Compare the paging add-on, not the base seat.
• Already on PagerDuty and happy with paging: keep PagerDuty for alerts and add a Slack-native incident tool only if your channels are chaos. Our PagerDuty alternative page shows when replacing it costs less than stacking.
• Status page used by the whole company: check reader caps. Several products count everyone who signs in to a private page. The internal status page comparison works through that cost for a 600-person company.

How IncidentBot works in Slack

/incident opens a channel, pages the on-call responder through your escalation policy and starts the timeline. On Team and above it also assigns commander, comms lead and scribe. /incident update drafts a status page update from what the comms lead wrote, and a person presses publish. When the incident is resolved, the postmortem draft is built from the timeline. The full command list is on the Slack incident management app page.

What is the best Slack app for incident management?

For teams of 10 to 50 engineers that run incidents in Slack, the best app is one that includes on-call paging and a status page in the seat price, so one tool covers the alert, the channel and the customer update. incident.io, Rootly and IncidentBot fit that profile. Smaller teams can start on FireHydrant Free or Zenduty Starter.

Is there a free Slack app for incident management?

FireHydrant has a free plan for up to 10 responders and incident.io has a free Basic plan with limits. Both are fine for learning the process. Once you need phone paging at night and a status page, every option on this list is paid, and the free plans stop covering a real rotation.

Do Slack incident apps page the on-call engineer?

Not always. Some include schedules, escalation and phone paging in the seat price, others sell on-call as a separate product or add-on. incident.io charges 10 to 20 USD more per user for on-call and Rootly sells it as a second 20 USD product. IncidentBot, PagerDuty and Zenduty include paging.

Can a Slack incident app update the status page?

Yes, most of them can. The useful version drafts the update from the incident and lets a person publish it, instead of making someone open a separate status page tool during the outage. Check whether the status page is included or sold as an add-on before you compare prices.

Do stakeholders need a paid seat to follow incidents in Slack?

It depends on the vendor. Some count anyone who joins incidents, others offer viewer licenses only on enterprise plans. In IncidentBot people who only follow incidents are read-only viewers, included in every plan and never billed.
