PagerDuty Professional at $21 per user per month billed annually is the default pick for most teams that want on-call paging inside Slack, while Spike at $7 per user per month is the lowest cost option here. Opsgenie is not in this list because Atlassian ended sales on 4 June 2025 and support ends on 5 April 2027. The headline price can hide the real cost, because incident.io charges $10 per user per month extra for on-call on Team, Rootly charges $20 for On-Call on top of $20 for Incident Response, and Grafana Cloud IRM adds a $19 platform fee.
Pick by how your team works in Slack. Some tools send an alert to Slack and let you acknowledge it there. Others open a dedicated Slack channel for each incident. Prices below come from official vendor pricing pages opened on 12 November 2026.

The 9 best pagerduty alternatives that integrate with slacks, in detail
PagerDuty
Best for: Teams that want the standard on-call tool in Slack
PagerDuty is the reference point here, and it stays in the list because it is still a real option with a published price. The Free plan covers up to 5 users with 1 on-call schedule, 1 escalation policy and 100 SMS or phone notifications a month. Professional costs $21 per user per month billed annually, or $25 billed monthly, and it adds unlimited schedules, 2 teams and 1 external status page with 250 subscribers.
- Responders can receive alerts in Slack, acknowledge them and check who is on-call there.
- The limit is the add-on list, because AIOps, Runbook Automation, Status Pages and Live Call Routing are sold separately on Professional.
- Above Professional, the PD Reliability Platform starts at $2,800 per year for 10 seats.

- Free plan for up to 5 users
- Slack app included on Professional

Business costs $14 per user per month billed monthly and adds unlimited phone and SMS alerts, war rooms and Jira integration.
- Enterprise is custom priced.
- The Slack detail that sets Spike apart is control at the escalation step.
- A manager can set a step to call one person, send an SMS to another, or ping a Slack channel with @here or @channel.

Pros

Cons

ilert is a strong fit for a small team that wants to start at $0 and move up only when the rotation grows. The Free plan covers up to 5 users with 1 on-call schedule, 1 escalation policy, 1 status page and 100 SMS or voice notifications a month. Pro costs $19 per user per month billed annually, with a minimum of 3 users, and it adds unlimited SMS and voice notifications, single sign-on and 250 AI credits per month.

- Enterprise costs $21 per user per month and adds unlimited stakeholders and an on-premise option.
- The Slack link covers alert routing, on-call schedules and incident updates in the channel where the team already works.
- The trade-off is plan depth, because a team that needs status pages or advanced workflows will need Premium or Enterprise.

Pros
- Free plan for small teams
- Pro at $9 per user per month
- Premium adds up to 10 free stakeholders

- Advanced adds unlimited SMS and voice
Cons
- Starter stops at 25 users and then the whole team moves to Base at $39

Grafana Cloud IRM
Best for: Teams already running Grafana Cloud

Team costs $15 per user per month billed annually, and on-call adds $10, so the all-in cost is $25 per user per month.

How we chose
We chose tools with a published Slack integration, a real on-call schedule and a pricing page opened on 12 November 2026. Prices come from official vendor pricing pages opened today. We did not test any tool hands-on. Opsgenie was left out because Atlassian ended sales on 4 June 2025 and support ends on 5 April 2027, and Grafana OnCall open source was left out because it was archived in March 2026.
