Learn About Siren
Understand how Siren works, why we built it the way we did, and how it compares to the alternatives.
Why Teams Switch
Most incident alerting tools charge per seat. That made sense when only a few people carried pagers, but modern teams want everyone to have visibility. When your bill grows every time you add someone to the rotation, you start making compromises.
Siren charges $10/month for 50 incidents. Add your whole team—same price. No seat licenses, no "contact sales," no surprises.
How It Works
Why Email for Alert Ingestion
No webhooks to configure, no API keys to manage. Send us an email, we'll page your team. Here's why we built it that way.
