Documentation Overview
WhaTools — free WhatsApp tools
wha.tools is a free toolkit of WhatsApp utilities and plain-language reference guides — link generators, a QR generator, a share-widget builder, a bulk sender helper, a phone-number validator, a link-preview debugger, and a WhatsApp Business API pricing calculator. No sign-up, and the interactive tools run entirely in your browser.
This repository is the public information hub for the project: what the tools are, and the machine-readable / agent-facing surfaces the site exposes. The web application's source lives in a separate private repository; nothing here is required to use the site.
