Overview

Zender is an SMS and WhatsApp gateway platform that StoresWiki LLC hosts and operates for you, turning ordinary Android devices into messaging gateways you control. Instead of paying per-message reseller rates, you connect your own SIM-equipped phones and send SMS and WhatsApp messages through them via a clean dashboard and developer API. It works as a self-hosted alternative to traditional messaging resellers, giving you ownership of the sending channel.

The platform pairs a web control panel with a device companion app and a REST API, so you can dispatch one-off messages, run bulk campaigns, queue sends, and integrate notifications directly into your own software. A built-in subscription model lets you offer gateway access to your own customers as a SaaS, with plans and credit limits you define.

StoresWiki LLC runs the server side from cabscloud.com, managing hosting, the send queue, security patching, and transactional email through our managed relay. You connect devices and build integrations; we keep the gateway service available, monitored, and up to date.
