GoWA

GoWA (Go WhatsApp Web Multi-Device) is an open-source WhatsApp REST API server built with Go, designed for developers and businesses who need programmatic access to WhatsApp messaging. It connects directly to WhatsApp using the multi-device protocol, providing a fast, memory-efficient gateway with both a web interface and a comprehensive REST API.

Common Use Cases

Customer support teams use GoWA to integrate WhatsApp messaging into their helpdesk systems, enabling agents to respond to customers through existing tools. Marketing teams automate order confirmations, appointment reminders, and promotional messages through the REST API. Developers build chatbots that receive messages via webhooks and respond automatically using the send API. System administrators set up alerting pipelines that forward server notifications to WhatsApp groups.

Why deploy GoWA on Hostinger VPS

Running GoWA on a Hostinger VPS gives you a dedicated, always-on WhatsApp gateway with no third-party rate limits or message fees. Your session data and message history stay on your own server, ensuring privacy and compliance. With full root access you can integrate GoWA with other services on the same VPS, configure custom webhook endpoints, and scale resources as your messaging volume grows.
