​

Siren is a communication infrastructure platform purpose-built for AI agents and automated systems. Instead of manually integrating multiple messaging providers, Siren acts as the communication rails—handling message delivery, routing, and orchestration across channels.

It empowers your AI agents to trigger, manage, and optimize real-time communication with users via SMS, Email, WhatsApp, Push, and In-App messages—all from a single, unified interface.

​
Why Siren?

  • AI agent-ready architecture: Siren includes a dedicated AI agent toolkit that can learn from the documentation and automatically handle backend integration into your systems. Once integrated, the agent can perform a wide range of actions, from sending messages to configuring notification webhooks.
  • Seamless Integration: We value your time. You can integrate Siren into your systems and trigger notifications in less than a minute. Whether you’re using the UI or APIs, getting started is frictionless.
  • Intuitive notification pipeline builder: Setting up automated message flows in Siren doesn’t require technical expertise. The intuitive no-code interface lets you design communication journeys visually, helping teams move fast without waiting for code changes.
  • Move fast with direct messaging: When speed matters, Siren gives you the ability to send messages instantly using a single API call and other methods. Whether it’s a critical update or a time-sensitive announcement, you can reach users across any channel without building a full notification logic.
  • Built-in visibility and reliability: Siren helps you stay in control at all times. You have full visibility into your notifications, and built-in fallback logic ensures messages are rerouted through alternate channels if the primary one fails. That way, nothing important slips through.
  • Simpler APIs with minimal payloads~~ Siren makes it easy for developers and systems to integrate with clear, compact API structures. You don’t need to understand deeply nested formats or complex schemas to trigger a workflow or send a message; just pass the essential data, and Siren takes care of the rest.~~
  • Multi-Channel Template Management
    Design, customise and manage notification templates from a centralised interface. This feature allows users to create tailored templates for each channel.
  • Centralised Dashboard
    Access a comprehensive dashboard displaying activity metrics account activities. This view provides real-time activity metrics and account insights to monitor and optimise notification effectiveness.
  • Logs
    Access detailed delivery metrics and analytics for sent notifications, providing visibility and actionable insights into your communication efforts.

​
