What Grafana OnCall Does Well
Grafana OnCall deserves genuine credit. It's a free, open-source on-call management tool that handles scheduling, escalation policies, and alert routing -- and it does all of this without charging a dime. For teams already running Grafana for dashboards and alerting, OnCall slots in naturally as part of the ecosystem.
The scheduling is solid. You get rotation support, shift swaps, override schedules, and calendar exports. Escalation chains work the way you'd expect: define who gets paged first, set timeouts, and route to the next person if there's no acknowledgment. It integrates directly with Grafana Alerting, so alerts from your Prometheus, Loki, or other data sources flow straight into on-call workflows.
The open-source model is a real advantage. You can self-host it, audit the code, and contribute back. There's no vendor lock-in on the on-call layer, and the community is active. For engineering teams that value open-source incident management and already run Grafana, OnCall is a genuinely strong choice.
Where Teams Look for Alternatives
Grafana OnCall is excellent within its niche, but there are real reasons teams look elsewhere:
Grafana ecosystem dependency. OnCall is designed to work as part of the Grafana stack. If you're not running Grafana for dashboards and alerting, adopting OnCall means either adopting the broader ecosystem or accepting an awkward integration experience. Teams using Datadog, New Relic, or even just basic uptime monitoring tools may find the Grafana dependency more friction than it's worth.
No built-in monitoring. Grafana OnCall manages on-call schedules and routes alerts, but it doesn't monitor anything itself. You still need a separate monitoring tool (Grafana Synthetic Monitoring, Prometheus, a third-party uptime checker) to actually detect when things go down. For teams that want monitoring and on-call in one place, this means stitching together multiple components.
No status pages. OnCall doesn't include public or internal status pages. If you need to communicate incidents to customers or stakeholders, you'll need a separate tool like Instatus, Cachet, or a platform that bundles status pages in.
Like most alerting-focused tools, Grafana OnCall covers one of three core needs -- it pages the right person. But dependency monitoring and customer-facing status pages require additional products, which means more tools to manage even if OnCall itself is free.
Self-hosting complexity. The cloud version (via Grafana Cloud) is straightforward, but self-hosting OnCall means maintaining another service -- with its own database, message queue, and dependencies. That's manageable for platform teams, but it's overhead that smaller teams may not want.
Alert fatigue configuration. OnCall's flexibility is a double-edged sword. Getting alert routing, grouping, and escalation policies tuned correctly requires investment. Less opinionated tools can be easier to set up for teams with straightforward on-call needs.
5 Best Grafana OnCall Alternatives
1. Alert24 -- Monitoring, On-Call, and Status Pages Without Grafana
Alert24 bundles uptime monitoring, on-call management, and status pages into a single platform. Instead of assembling separate tools for each layer, you get everything in one place -- no Grafana ecosystem required.
Where it wins:
- All-in-one platform. Monitoring, escalation policies, and status pages without needing to run Grafana, Prometheus, or any other supporting infrastructure.
- Third-party dependency monitoring. Alert24 monitors 2,000+ third-party status pages (AWS, Stripe, Cloudflare, GitHub, Vercel, and more) with AI-powered custom provider parsing. Grafana OnCall doesn't track third-party dependencies at all.
- Auto-updating status pages. Status pages reflect real-time monitor status without manual intervention. Alert24 is one of the few tools that both monitors third-party status pages and provides your own public status page -- when a dependency goes down, your page updates automatically to reflect the impact.
- Email-to-incident parsing. Forward alert emails from other tools into Alert24 and it creates structured incidents automatically.
- 100+ pre-built webhook integrations. Connect to Slack, Teams, PagerDuty, Jira, and other tools out of the box.
- Workspace-based pricing. No per-seat charges.
Where it falls short:
- Grafana OnCall is free and significantly more flexible if you're already in the Grafana ecosystem. If your team runs Grafana dashboards and Prometheus, OnCall is the natural choice and costs nothing.
- No log management or metrics collection. Alert24 focuses on monitoring and incidents, not full observability.
- No synthetic monitoring for simulating multi-step user flows.
- 60-second minimum check intervals. Not an issue for most teams, but worth noting.
- Smaller team and community than Grafana's. Less ecosystem depth, fewer third-party integrations at the deep bidirectional level.
- Less mature product overall. Grafana OnCall benefits from a large open-source community and Grafana Labs' resources.
Alert24 makes sense for teams that want on-call management bundled with monitoring and status pages, without adopting the Grafana ecosystem. Teams already invested in Grafana should stick with OnCall.
2. PagerDuty -- The Enterprise Standard
PagerDuty is the tool most large organizations already use for on-call management. It has the deepest integration ecosystem, the most mature escalation engine, and the kind of enterprise features (audit logs, analytics, SSO, compliance) that procurement teams look for.
Where it wins:
- Most extensive integration catalog in the category. Nearly every monitoring and ticketing tool has a native PagerDuty integration.
- Advanced event intelligence for noise reduction and alert grouping.
- Mature analytics for on-call load balancing, MTTA/MTTR tracking, and postmortem workflows.
- Enterprise-grade compliance (SOC 2, HIPAA-ready).
- Extremely reliable. PagerDuty's infrastructure has a strong uptime track record.
Where it falls short:
- Expensive. Pricing starts reasonable but scales quickly with seats and add-ons. The full-featured plans can be 5-10x the cost of alternatives.
- No built-in monitoring. Like Grafana OnCall, PagerDuty routes alerts from other tools -- it doesn't generate them.
- No status pages. You'll need a separate tool for external incident communication.
- The UI has accumulated complexity over the years. Newer teams may find it overwhelming.
PagerDuty is the right choice for large engineering organizations with complex on-call needs and the budget to match. It's overkill for a small team monitoring a handful of services.
3. Better Stack -- All-in-One Monitoring and Incident Management
Better Stack bundles uptime monitoring, log management, on-call scheduling, and status pages into a single platform. It's the most feature-complete all-in-one option on this list.
Where it wins:
- Full observability stack: monitoring (30-second checks), log management, on-call scheduling, and status pages.
- Polished, modern UI with fast setup.
- Bundled pricing can save money compared to buying separate tools.
- Generous free tier for getting started.
- Larger team and more mature product than most newer alternatives.
Where it falls short:
- Per-seat pricing can add up for larger teams.
- No third-party dependency monitoring.
- The full bundle means you're paying for log management even if you don't need it (though the bundled price may still be competitive).
- Less flexible than Grafana OnCall for teams that want to own their alerting rules and data model.
Better Stack makes sense for teams that want a complete, hosted platform without stitching components together. If you need logs and monitoring in one place, it's one of the best options available.
4. Rootly -- Slack-Native Incident Management
Rootly takes a different approach by making Slack the center of incident response. Instead of a separate UI for managing incidents, everything happens in Slack channels -- creating incidents, running workflows, assigning roles, and tracking timelines.
Where it wins:
- Deep Slack integration. Incidents are managed directly in Slack with dedicated channels, automated role assignments, and status updates.
- Automated runbooks and workflows triggered by incident creation.
- Strong postmortem and retrospective tooling with auto-generated timelines.
- Good for organizations where Slack is already the primary communication tool during incidents.
- Integrates with PagerDuty, Opsgenie, and other paging tools for the alerting layer.
Where it falls short:
- Slack dependency. If your team uses Teams, Discord, or something else, Rootly loses much of its value.
- No built-in monitoring. You still need a separate tool for uptime checks and alerting.
- No status pages.
- Pricing can be steep for smaller teams.
- Less useful for small teams where incidents are infrequent and a Slack-native workflow is overkill.
Rootly is the right fit for mid-to-large engineering teams that already live in Slack and want incident response deeply embedded in their communication workflow.
5. Spike.sh -- Budget-Friendly On-Call Management
Spike.sh is a focused on-call and incident management tool built for smaller teams who want PagerDuty-style functionality without PagerDuty pricing.
Where it wins:
- Very affordable. Plans start low and include phone call, SMS, Slack, and email alerting.
- Clean, straightforward UI. Setup takes minutes, not hours.
- On-call scheduling with rotations and escalation policies included.
- Integrations with common monitoring tools (Grafana, Datadog, UptimeRobot, AWS CloudWatch).
- Good value per dollar for small-to-medium teams.
Where it falls short:
- No built-in monitoring. Like Grafana OnCall and PagerDuty, Spike.sh routes alerts -- it doesn't generate them.
- No status pages.
- Smaller company with a more limited feature set than PagerDuty or Better Stack.
- Fewer enterprise features (limited analytics, no event intelligence).
- Less community and ecosystem around it than open-source alternatives.
Spike.sh is a solid pick for small teams that need on-call scheduling and multi-channel alerting without the enterprise price tag. If your needs are straightforward, it delivers the core value at a fraction of PagerDuty's cost.

The Bottom Line
Grafana OnCall is an excellent tool that deserves its adoption. If your team already runs Grafana and Prometheus, OnCall is the obvious choice for on-call management -- it's free, open source, and integrates directly with your existing alerting pipeline. Don't switch away from it just because something newer exists.
But Grafana OnCall is specifically an on-call management tool within the Grafana ecosystem. It doesn't monitor your services, it doesn't host status pages, and it assumes you're running (or willing to run) the Grafana stack.
Alert24 is a good fit for teams that want monitoring, on-call management, and status pages in a single standalone platform -- without adopting the Grafana ecosystem. The third-party dependency monitoring (2,000+ services) and auto-updating status pages fill gaps that Grafana OnCall doesn't address. But be honest about the tradeoffs: you're giving up the flexibility and open-source community that Grafana provides, and getting a less mature product with a smaller ecosystem.
PagerDuty remains the enterprise standard if budget isn't the primary constraint. Better Stack is the most feature-complete all-in-one platform. Rootly is the pick for Slack-native incident response. Spike.sh delivers core on-call functionality at a budget price.
Choose based on what your team actually needs. If you're in the Grafana ecosystem, OnCall is hard to beat. If you want a single platform that handles monitoring and on-call without the ecosystem dependency, the alternatives above each serve that need in different ways.
