How we chose these Opsgenie alternatives

We looked for open-source tools that cover parts of Opsgenie: detecting problems, routing alerts to the right people, on-call scheduling, and incident response. We verified each project's license, recent activity, stars, and self-hosting in its repository. Opsgenie is an alert and on-call platform that receives alerts from monitoring tools, while many alternatives are monitors that generate alerts, so we separate monitoring from on-call management. See our methodology for the full criteria.

Important: monitors vs on-call management

Uptime Kuma, Gatus, and Nagios detect failures and send notifications, but they do not provide on-call rotations and escalation policies. Keep centralizes and routes alerts from other tools. OneUptime, Wachd, and Uptimepage add on-call scheduling and incident management, and Operational notifies you about product events rather than infrastructure incidents.

What replaces which part of Opsgenie

For alert aggregation and routing, use Keep or Wachd, which receive alerts from Grafana, Datadog, and Prometheus. For on-call schedules and escalation, look at OneUptime, Wachd, or Uptimepage. For basic monitoring and notifications, Uptime Kuma, Gatus, and Nagios are enough, and many teams combine them with a dedicated on-call tool.

License details

Uptime Kuma and Keep's core are MIT, with Keep's ee directory under a separate license. Gatus and Wachd are Apache-2.0, OneUptime is Apache-2.0 with an enterprise directory, and Nagios Core is GPL-2.0. Operational and Uptimepage are AGPL-3.0.

Self-hosting

All eight can be self-hosted: Uptime Kuma and Gatus run as a single container or binary, Wachd needs Kubernetes, and Keep and OneUptime are heavier platforms. Operational and Uptimepage also offer hosted services.

Maintenance status

Uptime Kuma, Keep, Gatus, OneUptime, Nagios, Operational, Wachd, and Uptimepage were all updated within days or weeks of this update. Wachd and Uptimepage are very small and new projects.

Why look for a Opsgenie alternative?

Opsgenie is a proprietary Atlassian product for alert routing, on-call schedules, and escalation, billed per user, and Atlassian has announced it is winding the product down in favor of Jira Service Management. Open-source alternatives let you self-host alerting, keep monitoring data private, and avoid per-seat pricing, at the cost of assembling monitoring, alerting, and on-call tools yourself.
