• Reduced Operational Burden: As a fully managed SaaS, OnCallManager handles all the infrastructure, updates, and maintenance. Your team can focus entirely on managing incidents, not on managing the on-call tool itself.
• Focused Feature Set: OnCallManager provides the core features necessary for effective on-call management – rotations, schedules, escalations, and notifications – without the bloat of enterprise-grade features that many small to medium-sized teams don't need.

OnCallManager is designed for teams who value speed, simplicity, and a truly integrated Slack experience, making it an excellent Grafana OnCall Slack alternative.

When to Choose Grafana OnCall

Grafana OnCall is an excellent choice for specific scenarios and team structures:

• Deep Integration with the Grafana Ecosystem: If your team already relies heavily on Grafana for observability, metrics, logs, and dashboards, choosing Grafana OnCall provides a cohesive, single-pane-of-glass experience. Alerts from Prometheus, Loki, and Grafana Alerting will naturally flow into your on-call schedules.
• Need for Self-Hosting and Full Control: Organizations with stringent security, compliance, or data residency requirements may find the self-hosted option of Grafana OnCall invaluable. It offers complete control over your infrastructure and data.
• Complex, Highly Customized Alerting Needs: For teams that require very granular control over their alert routing, aggregation, and suppression logic, Grafana OnCall's YAML-driven configuration and extensive API provide the flexibility to build highly sophisticated workflows.

Operational Shifts: Migrating from Grafana OnCall to OnCallManager

Considering a switch from Grafana OnCall to OnCallManager? Understanding the operational changes involved can help you plan a smooth transition. The core shift involves moving from a Grafana-centric or infrastructure-as-code approach to a Slack-native, managed service.

1. Alert Source Redirection:
   • Grafana OnCall: Typically receives alerts directly from Grafana Alerting, Prometheus, Loki, or its own API.
   • OnCallManager: Relies on generic webhooks or a simple API. You'll redirect your existing alert sources (e.g., Grafana Alerting, Prometheus Alertmanager, or other monitoring tools) to send their notifications to OnCallManager's webhook endpoints. This is usually a straightforward configuration change in your monitoring system.
2. Schedule and Rotation Management:
   • Grafana OnCall: Schedules are defined through the Grafana UI or YAML configuration files.
   • OnCallManager: Schedules and rotations are created and managed directly within Slack using intuitive commands or a simple web interface. This means less time wrestling with YAML and more time using a familiar chat interface. Learn more about how to set up on-call rotation with OnCallManager.
3. Escalation Policy Configuration:
   • Grafana OnCall: Offers highly customizable escalation policies, potentially with conditional logic configured via UI or YAML.
   • OnCallManager: Provides flexible, tiered escalation policies that are simple to set up and manage within Slack. While it might not have the same depth of conditional logic as Grafana OnCall, it covers the vast majority of common escalation needs efficiently.
4. Notification and Alert Delivery:
   • Grafana OnCall: Can send notifications via various channels including Slack, email, SMS, and push notifications, often configured within the Grafana ecosystem.
   • OnCallManager: Primarily focuses on Slack notifications, leveraging rich Slack messages for alert details, acknowledgment buttons, and escalation actions. This reinforces the Slack-native experience. If you're looking for an incident response workflow in Slack, OnCallManager fits perfectly.
5. Reduced Infrastructure Maintenance:
   • Grafana OnCall (Self-hosted): Requires ongoing maintenance, updates, and troubleshooting of your Grafana OnCall instance and its underlying infrastructure.
   • OnCallManager: As a managed service, all infrastructure, security, and updates are handled by the OnCallManager team. This significantly reduces your team's operational burden and allows them to focus on core engineering tasks.

The migration process is less about re-architecting your entire monitoring stack and more about re-pointing your alert destinations and adapting to a Slack-first workflow for schedule and incident management.

Who Should NOT Switch to OnCallManager (from Grafana OnCall)

While OnCallManager offers compelling benefits, it's not the right fit for every team currently using Grafana OnCall. You might reconsider switching if:

• You're Deeply Embedded in Grafana's Broader Incident Management Ecosystem: If you're not just using Grafana OnCall for rotations but also leveraging Grafana's full suite of incident management features, runbooks, and detailed analytics that are tightly coupled, moving to OnCallManager might introduce a separate workflow rather than unify it. OnCallManager excels at on-call rotations and basic alerting, but doesn't aim to be a full-fledged incident command system like some other tools.
• Your Organization Has Strict Self-Hosting Requirements: If your company policy mandates that all critical tools, especially those handling alerts, must be self-hosted on your own infrastructure, a managed SaaS like OnCallManager won't meet this requirement.
• You Prefer YAML-Heavy Customization and Infrastructure-as-Code for On-Call: For teams that actively prefer to manage their on-call schedules, policies, and integrations through YAML files and version control, OnCallManager's UI and Slack-command driven approach might feel less empowering. The overhead of YAML is a feature, not a bug, for these teams.

OnCallManager is designed for simplicity and a Slack-native experience. If your current Grafana OnCall setup aligns with the scenarios above, its power and customizability might still be the better choice for your specific needs.
