Relay is a full-stack SMS API and messaging platform built for developers, businesses, and service providers that need a centralized way to send, manage, and monitor SMS communications.
The platform combines user-friendly messaging tools with developer-focused APIs. Users can send single or bulk SMS messages, review delivery history, manage their balance and packages, generate API keys, and access API documentation from a dedicated dashboard.
Administrators receive complete operational control over users, SMS packages, system balances, connected gateway devices, SMTP configuration, website content, and platform settings.

Relay was migrated from a Vite-based React application to a modern Next.js App Router architecture. The migration introduced server-side capabilities, structured routing, reusable layouts, optimized data access, and a more scalable foundation for future development.
The result is a polished, developer-ready communication platform that brings messaging, API access, gateway monitoring, account management, and administrative operations into one cohesive system.
