duochat is a developer-first WhatsApp API platform built to help teams integrate WhatsApp messaging into their applications quickly, reliably, and at a predictable cost. Most WhatsApp Business API providers charge per conversation or per message, which makes scaling expensive and difficult to forecast. duochat follows a flat pricing approach with unlimited messaging, so developers can build and grow without worrying about message-based billing. The platform is designed to work as a backend communication layer that connects your app, CRM, or automation system directly to WhatsApp. You control the entire conversation flow using APIs and webhooks, while duochat handles the WhatsApp infrastructure in the background. duochat is suitable for both simple use cases like sending alerts and advanced use cases like building full chatbot systems and AI-driven workflows.

• No per-message or per-conversation fees
