The Verdict

These tools serve fundamentally different purposes. PagerDuty is purpose-built for incident management and on-call operations, making it essential for DevOps teams managing critical systems. Slack excels at general team communication with a generous free tier. Most teams running production systems actually need both - Slack for daily communication and PagerDuty for incident response.

How to switch from PagerDuty to Slack

1Export your data from PagerDuty first: go to Analytics > Export for incident history CSVs, and use Schedules > Export or the REST API (/schedules, /escalation_policies, /services endpoints) to pull on-call rotations and escalation rules before you cancel your subscription.
2Set up your Slack workspace structure - create dedicated channels like #incidents, #on-call, and #alerts to mirror how your team organized PagerDuty services.
3Since Slack has no native on-call scheduling, decide whether to manually manage rotations in a shared calendar/spreadsheet posted to Slack, or connect a lighter-weight on-call tool (like Opsgenie's free tier) that integrates with Slack.
4Reconnect your monitoring tools (Datadog, New Relic, UptimeRobot, etc.) directly to Slack via their native Slack integrations or incoming webhooks so alerts land in your #alerts channel.
5Recreate critical runbooks and escalation steps as pinned messages or linked docs (Notion/Google Docs) in the relevant Slack channels, since PagerDuty's response plays won't transfer automatically.
6Run both tools in parallel for 2-4 weeks during an on-call rotation cycle to confirm nothing falls through the cracks, then cancel PagerDuty once the team has fully adopted the new Slack-based workflow.

PagerDuty vs Slack: common questions

How do I export my incident history and on-call schedules from PagerDuty?+

PagerDuty lets you export incidents, schedules, and escalation policies as CSV files from the web app (Analytics > Export, or Schedules > Export), or pull the same data programmatically via the REST API. There's no one-click full-account export, so for a complete archive you'll need to hit multiple endpoints (incidents, services, escalation policies, schedules) separately.

What do I lose if I move incident response from PagerDuty to Slack?+

You lose native on-call scheduling, escalation policies, SMS/phone alerting, and incident-specific analytics like MTTA/MTTR - Slack has none of these built in. You'd need to bolt on a third-party on-call tool (like Opsgenie, Splunk On-Call, or PagerDuty itself connected to Slack) to replicate that functionality.

Is Slack's free plan enough for a small team's alerts and communication?+

For general team chat, yes - the free plan supports unlimited users and covers most day-to-day needs, though message history is capped at 90 days. For anything alert-related (uptime pings, monitoring webhooks), it works fine as a notification channel, but it has no memory of who's on-call or how to escalate an unacknowledged alert.

Can I still get PagerDuty-style alerts inside Slack?+

Yes - PagerDuty has an official Slack integration that posts incident updates and lets you acknowledge/resolve incidents from Slack, so many teams keep both tools rather than fully switching. If you drop PagerDuty entirely, you'd route monitoring alerts (Datadog, UptimeRobot, etc.) directly into Slack channels via webhooks, but you lose automated escalation if nobody responds.

How much would we actually save switching from PagerDuty to Slack?+

For a 10-person team, PagerDuty Professional runs about $2,520/year versus Slack Pro at roughly $870/year (or $0 on the free plan) - a savings of $1,650-2,520/year. That savings only makes sense if you don't need dedicated incident management; otherwise you'll spend it back on a replacement on-call tool.
