Simple Web WhatsApp Blaster

I need a lightweight web-based tool that lets me fire off WhatsApp campaigns to large contact lists in one go. The core requirement is straightforward: once I upload an Excel sheet of numbers, the system should connect to my active WhatsApp session (web API or any proven workaround), pull each contact, and send a predefined text message to all of them automatically. Getting reply too Key details • Primary action is bulk sending; scheduling or analytics can be left for future iterations. • Contacts arrive exclusively through Excel uploads for now, but it would be helpful if the codebase is organized so additional file types (CSV or plain TXT) could be enabled later without major rewrites. • A simple dashboard that shows basic status feedback while messages are going out (total numbers processed, successes, and any immediate failures) will be enough for this version. Tech notes & acceptance • Web interface can be plain HTML/CSS/JavaScript backed by PHP, Node.js, or Python—feel free to use the stack you’re fastest with, as long as setup instructions are clear. • I should be able to deploy it on a standard shared hosting or a small VPS; keep external dependencies minimal. • Provide full source code, a short README for installation, and a quick demo video or screenshots proving the blast works with a sample Excel file. If the tool reliably imports an Excel list and sends the message to every contact in that sheet, the job is done.
