Open-source alternatives to PagerDuty

PagerDuty is an incident response platform used by operations and engineering teams to route alerts, manage on-call schedules, and coordinate response during outages. It integrates with monitoring tools (Datadog, Grafana, CloudWatch) and communication channels (Slack, phone, SMS) to ensure alerts reach the right person at the right time with escalation policies.

Comparison notes

Grafana OnCall (Apache 2.0) is the primary OSS alternative covering on-call scheduling, alert routing, and Slack/phone escalation — formerly Amixr, acquired by Grafana Labs. The main gaps vs. PagerDuty: PagerDuty's AIOps (event correlation and noise reduction) has no OSS equivalent at comparable maturity. PagerDuty's stakeholder communication features (status pages, executive briefings) require additional tools when self-hosted. PagerDuty's phone-call and SMS alerting requires third-party provider configuration (Twilio) in self-hosted OnCall vs. PagerDuty managing the telephony infrastructure. Note: The alternatives list incorrectly includes OpenHands (a development platform) — the relevant OSS tool is Grafana OnCall.

Migration tips

  • Export PagerDuty on-call schedules, escalation policies, and service configurations via the PagerDuty API before migrating
  • Recreate on-call rotation schedules in Grafana OnCall or equivalent, including override rules and holiday exceptions
  • Configure Twilio or another telephony provider in your OSS tool for phone and SMS alerting (this is not managed for you)
  • Update monitoring tool integrations (Datadog, Grafana) to send alerts to your new on-call platform's webhook URLs
  • Run both systems in parallel for one on-call cycle to validate alert routing before cutting over

FAQ

Can I fully replace PagerDuty with an OSS tool?

Feature parity varies. Most OSS alternatives cover 70-90% of core workflows, but may lack polish, integrations, or specialized features. Pilot the alternative with a subset of your team before fully committing.

What's the cost of self-hosting?

Plan for ~$5-50/month in VPS costs (DigitalOcean, Hetzner, etc.) plus 2-8 hours/month in maintenance. For a team of 20+, self-hosting usually breaks even against SaaS pricing within 6-12 months.

Which alternative should I pick?

Sort by GitHub stars (a proxy for community health), check the last-pushed date (avoid unmaintained projects), and read recent issues to gauge responsiveness.
