Siren vs Opsgenie

If you're researching Opsgenie, there's something you should know first: Atlassian has stopped selling new Opsgenie subscriptions and is sunsetting the product. Existing customers have until April 2027 to migrate to Jira Service Management or find an alternative.

That changes the conversation.

The Short Version

Opsgenie was a solid, cost-effective alternative to PagerDuty—especially if you were already in the Atlassian ecosystem. But it's going away, and Atlassian wants you to move to Jira Service Management, which is a much larger (and more expensive) platform.

If you just need on-call alerting and don't want to adopt a full ITSM suite, Siren does what Opsgenie did—phone calls, rotations, escalations—without the platform lock-in or the migration deadline.

Pricing

Siren charges $10/month for 50 incidents, then $0.20 per incident after that. Add your whole team—same price.

The Opsgenie Situation

Atlassian acquired Opsgenie in 2018. In 2024, they announced Opsgenie would be folded into Jira Service Management and Compass. New signups are closed. Existing customers must migrate by April 5, 2027.

If you're evaluating Opsgenie today, you're evaluating a product with a known expiration date.

Your options:

1. Migrate to Jira Service Management — More features, higher price, requires buying into Atlassian's ITSM vision
2. Move to PagerDuty — The industry standard, but expensive
3. Find a focused alternative — Get the alerting features you actually need without the platform overhead

What Opsgenie Did Well

Credit where it's due:

• Atlassian integration — If you lived in Jira, Opsgenie fit naturally
• 200+ integrations — Broad compatibility with monitoring tools
• Competitive pricing — Cheaper than PagerDuty at most tiers
• Mobile apps — Solid iOS and Android experience

Where Siren Fits

Siren isn't trying to replace your entire ITSM stack. It does one thing: make sure the right person gets paged when something breaks.

• Unlimited seats — No per-user pricing
• Universal ingestion — Anything that sends email can create incidents
• Simple escalation — Primary gets paged, then secondary if no response
• No migration deadline — We're not going anywhere

How Siren Works

1. You get a Siren email address for each service
2. Point your monitoring tools at it (Datadog, Grafana, CloudWatch, anything)
3. When an alert comes in, Siren pages whoever's on-call
4. If they don't acknowledge, we remind them at 2 minutes
5. If still no response, we escalate to secondary at 5 minutes
6. We keep trying until someone responds or 15 minutes pass

No complex routing rules. No integration rabbit holes. It just works.

Infrastructure

You might assume $10/month means "runs on a single server somewhere." It doesn't.

Siren runs on geo-redundant infrastructure across multiple regions. Our database is distributed across three locations. We use multiple telephony providers with automatic failover—if one has issues, your alerts still get through.

We don't publish an SLA yet—we're not at that stage. But we built Siren like we'd build it for ourselves: assume things will fail, and make sure pages still go out.

Who Should Migrate to Jira Service Management

• Teams already deep in the Atlassian ecosystem
• Organizations that need full ITSM capabilities (ticket management, service desk, asset tracking)
• Enterprises with budget for a comprehensive platform

Who Should Use Siren

• Teams who just need alerting, not a whole ITSM suite
• Anyone looking at Opsgenie alternatives before the 2027 deadline
• Small teams and startups watching their spend
• Organizations that want to avoid another platform migration in a few years

The Bottom Line

Opsgenie was a good product. But it's end-of-life, and Atlassian is pushing you toward a bigger, more expensive platform.

If you just need phone calls when your app is down, on-call rotations, and escalations—Siren does that for $10/month. No seat licenses. No migration deadline. No ITSM suite you didn't ask for.
