Chat alerts are easy to miss. When production is down, a Slack message can scroll past an engineer who has stepped away, but a phone call or SMS will not. That is why a dedicated pager layer remains essential even for teams that run everything in Slack. The best pager tools combine loud, reliable call and SMS delivery with escalation, so an unanswered page automatically moves to the next responder, and tie that paging to an accurate on-call schedule. Pagerly adds this paging layer on top of a Slack-native workflow rather than forcing a separate console.
A pager must reach the on-call engineer even when Slack is missed. Pagerly's on-call paging calls and texts with escalation.
If the first responder misses the page, it should escalate. Pagerly supports multi-level L1 to L2 to L3 escalation.
Paging is only as good as the schedule behind it. Create rotations with Pagerly and sync them to a Slack usergroup.
Pages should fire from Datadog, Sentry, AWS, and other monitors via integrations.
Only real incidents should page a human at night. Pagerly's alert annotation helps suppress noisy alerts so pages stay meaningful.
Pager pricing should not balloon with team size. See pricing; Pagerly charges paging at $4 per user per month on a flat per-team plan.
Pagerly drives reliable paging from Slack with escalation, schedules, and incident response, used by 1,000+ orgs including 1Password, Disney+, Spotify, and Loom. Set up paging using the paging docs.
