I Built a Unified Notification Library for Java (Email, Slack, Telegram, SMS, and more)

Every backend system eventually needs notifications. You send emails for confirmations, Slack alerts for deployments, SMS for verification codes, Discord messages for internal tools, and webhooks for integrations. The problem is that each channel has its own SDK, configuration style, authentication, and API. Before long, your codebase ends up looking like this: JavaMail for email Twilio SDK for SMS Slack webhook calls Telegram Bot API Custom HTTP clients for other services Every integration is different. So I built NotifyHub . The Idea NotifyHub is an open-source notification library for Java and Spring Boot that provides one unified API to send notifications across multiple channels. Instead of integrating every provider separately, you use a single fluent interface. Example: notify . to ( "user@email.com" ) . via ( Channel . EMAIL ) . fallback ( Channel . SLACK ) . subject ( "Order Confirmed" ) . content ( "Your order has shipped!" ) . send (); One API. Multiple channels. Supported C
