Short answer: Grafana OnCall OSS is archived and unsupported as of March 2026, and the maintained path is the paid Grafana Cloud IRM. Pagerly is a fully maintained, Slack-native on-call and incident tool that needs no self-hosting, with automatic @oncall usergroup sync and flat per-team pricing. If you are leaving Grafana OnCall OSS, Pagerly is the strongest landing spot.

Key takeaways

Why Grafana OnCall users need an alternative now

Grafana OnCall OSS entered maintenance mode in March 2025 and was archived on March 24, 2026. Its cloud connection for SMS, phone, and push notifications was turned off, so self-hosted users lose reliable notification delivery. Grafana now directs users to the paid Grafana Cloud IRM. Teams that relied on the open-source version need a maintained replacement, and waiting risks missed pages from an unsupported tool.

Real problems teams hit with Grafana OnCall

The OSS version is archived. It is no longer actively maintained, and notification delivery for self-hosters has been disrupted.
Self-hosting overhead. Running and patching the OSS app is operational work most teams would rather avoid.
The maintained path costs money. Grafana Cloud IRM is the supported route, so the free OSS advantage is gone.
Alert-focused in Slack. The Slack experience centers on alerts rather than a full incident workflow.

The migration fit framework: what actually matters

Score any Grafana OnCall replacement against these factors.

1. Active maintenance

Choose a tool that is supported and updated. An archived, unsupported codebase is a reliability risk for something as critical as paging.

2. No self-hosting

A managed tool removes the infrastructure, patching, and uptime burden of running your own on-call system.

3. Slack-native workflow

On-call and incidents should run in Slack if that is where your team works, rather than in a separate console.

4. Usergroup automation

The current on-call engineer should sync into a Slack usergroup automatically so mentions always reach the right person.

5. Predictable pricing

Flat, per-team pricing avoids per-seat growth and surprise renewals.

How to migrate from Grafana OnCall to Pagerly

Add Pagerly to your Slack workspace.
Recreate or import your rotations in Pagerly.
Connect monitoring tools such as Grafana, Datadog, Sentry, and AWS.
Enable automatic @oncall usergroup sync.
Decommission the self-hosted OnCall OSS instance once paging is verified.

Pricing compared: what you actually save

Grafana OnCall OSS was free but is now archived, so the real comparison is against the paid Grafana Cloud IRM or another per-seat tool. Pagerly is flat. The table uses an approximate 20 US dollars per user per month against Pagerly at a flat 500 US dollars per month.

Beyond direct cost, dropping self-hosting also removes the engineering time spent maintaining the OSS deployment, which is a real saving that does not show up on an invoice.
