Alternatives / PagerDuty
Looking for an open source PagerDuty alternative? We compared 6 open source alerting, monitoring, and status page tools by license, self-hosting, and incident features. Most are status pages or monitors rather than on-call paging tools, and several use open-core or source-available licenses.

| Alternative | Best for | License |
|---|---|---|
| Keep | Alert management and automation (has ee directory) | MIT + ee directory |
| OneUptime | Monitoring, incidents, and status pages (has ee directory) | Apache-2.0 + ee directory |
| Wachd | AI root cause analysis on alerts (very young) | Apache-2.0 |
| Kener | Status page and uptime monitor | MIT |
| Statusnook | Simple status pages (inactive since 2024) | MIT |
| StatusScout | Website health monitoring (source available) | StatusScout License 2.0 (source available) |
We looked for open-source tools that overlap with PagerDuty's core: receiving alerts, routing them to the right people, and managing incidents and status communication. We verified each project's license, recent activity, stars, and self-hosting in its repository. Dedicated open-source on-call scheduling is rare, so most of these cover alerting, incident handling, or status pages. See our methodology for the full criteria.
Kener, Statusnook, and StatusScout are status page and monitoring tools. They do not provide on-call schedules, escalation policies, or phone and SMS paging like PagerDuty. Keep centralizes alerts and automates responses, and OneUptime covers monitoring, incidents, and status pages, so they come closest, but none is a full PagerDuty replacement.
Keep is MIT outside its ee directory, and OneUptime is Apache-2.0 with an ee directory for Enterprise code. StatusScout uses a source-available license that restricts reselling it as a hosted service. Wachd is Apache-2.0, with paid tiers for cloud AI backends and compliance features, and Kener and Statusnook are MIT.
Wachd receives alerts from Grafana, Datadog, and Prometheus and adds AI-generated root cause analysis. It deploys with a Helm chart on Kubernetes and needs an AI backend you choose, such as Ollama, Claude, OpenAI, or Gemini. It was created in April 2026 and has only about 40 stars.
Keep, OneUptime, Kener, Wachd, and StatusScout had commits within weeks of this update. Statusnook has had no commits since October 2024, so it is inactive.
PagerDuty is a proprietary hosted service priced per user with add-ons for AI, runbooks, and status pages, and incident data stored on its platform. Open-source alternatives let you self-host alerts and incident data, avoid per-seat pricing, and integrate with your own monitoring stack, at the cost of running the platform and a weaker on-call paging layer.
Keep is an open-source AIOps and alert management platform that centralizes alerts from monitoring tools, correlates and summarizes them with AI, and automates responses with workflows, with integrations for tools such as CloudWatch, Datadog, and Grafana. The repository is MIT except for the ee directory, which is under a separate license, and it offers enterprise authentication such as SSO, SAML, OIDC, and LDAP.
Pricing: Free to self-host; Keep Cloud and enterprise features are paid.
OneUptime is an open-source monitoring and observability platform that covers uptime monitoring, incident management, on-call, status pages, logs, and traces in one product that can be self-hosted. The Community Edition is Apache-2.0, while an ee directory holds Enterprise code, and a managed OneUptime Cloud is available.
Pricing: Free to self-host the Community Edition; cloud and Enterprise plans are paid.
Kener is an open-source status page and uptime monitor with Docker deployment, 11 service types, incident management, scheduled maintenance, and subscriber notifications.
Pricing: Free and open source.
Statusnook is an open-source status page system with real-time updates, incident management, maintenance scheduling, brand customization, notifications, and endpoint monitoring, deployable in minutes.
Pricing: Free and open source.
Wachd is a self-hosted alert intelligence platform that receives alerts from Grafana, Datadog, and Prometheus and generates root cause analysis with an AI backend you choose, such as Ollama for air-gapped setups. It deploys with a Helm chart on Kubernetes or on a single server, is Apache-2.0, and has paid tiers for cloud AI backends and compliance features.
Pricing: Free open-source version with unlimited teams and users; paid tiers add cloud AI backends and compliance features.
StatusScout monitors security headers, SSL certificates, DNS records, exposed files, uptime, broken links, and user flows, and alerts you when something fails. It is self-hosted and free to run under the StatusScout License 2.0, which is source available with restrictions on reselling it as a hosted service. A managed cloud starts at $12 a month.
Pricing: Free to self-host; the managed cloud is paid.
| Alternative | Type | License | Self-hosted | Best for |
|---|---|---|---|---|
| Keep | Alert management | MIT + ee directory | Yes | Alert workflows |
| OneUptime | Observability platform | Apache-2.0 + ee directory | Yes | All-in-one |
| Kener | Status page and monitor | MIT | Yes | Docker deployments |
| Statusnook | Status page | MIT | Yes | Simple status pages |
| Wachd | Alert intelligence | Apache-2.0 | Yes | AI root cause analysis |
| StatusScout | Website monitoring | StatusScout License 2.0 | Yes | Security checks |
Want to centralize and automate alerts
Keep centralizes alerts from monitoring tools, correlates them, and automates responses, under MIT apart from its ee directory.
Want monitoring, incidents, and status pages in one
OneUptime covers uptime monitoring, incident management, and status pages, with enterprise code in an ee directory.
Want AI analysis of alerts on your own infrastructure
Wachd analyzes alerts from Grafana, Datadog, and Prometheus with a local or cloud AI backend, but it is very young.
Only need a public status page
Kener is an MIT status page and uptime monitor you deploy with Docker, but it does not page people.
