BuzzRelay: WhatsApp campaigns, AI auto-replies and leads from your PC

BuzzRelay is a WhatsApp marketing desktop app for Windows. Link multiple WhatsApp numbers and send personalised campaigns to thousands of contacts, with built-in anti-ban controls (random delays, quiet hours, typing simulation, daily and hourly limits, number warm-up). It also handles the replies: keyword and AI auto-replies, an inbox for chats that need a person. Find new leads on Google Maps, and track delivery and read receipts. One-time payment, no monthly fees.

I built BuzzRelay because small business owners were paying high monthly fees and message charges just to send updates to their own customers. Most tools also force you to upload customer contacts to their servers, which hurts privacy. BuzzRelay solves this as a Windows app you buy once for $27 with no monthly fees. It runs directly on your PC or VPS, so your customer list stays completely private and never touches cloud servers. It also has built-in features like randomized delays and quiet-hour pauses to protect your numbers. At first, it was a simple sender. But based on feedback, I added multi-number support, Excel imports, AI content generation, and built-in Chromium so it can run 24/7 on a cheap VPS.
