Raven is a scalable and robust notification delivery system. Raven provides a single API for developers to add Push Notifications, SMS, Email, WhatsApp, Slack etc in their backend. They can use any provider of their choice like Twilio, MessageBird, MSG91, Kaleyra etc. No need to check 5 different dashboards to get different data. You get a consolidated view of all communication that is going from your backend. Manage all your templates at one place and edit/preview them directly from the dashboard. Retry rules let you handle message delivery failures and make sure that your messages reach your users at any cost. In case if the provider is down, a single click switch will route your messages via another provider.We aim to make lives of developers and product managers easy by offloading the whole notification delivery system, so that they can focus on what they are building.
