Real-Time WhatsApp Forwarding

I am looking for a Windows-based solution that sits quietly in the background and mirrors everything posted in one WhatsApp group straight into another group the very moment it arrives. The essentials are:

• Platform: Windows only. It must install and run as a lightweight service or tray app without demanding a full server stack.
• Message types: please ensure automatic forwarding of both text messages and images. Speed matters; I want the copy to appear in the destination group in real time, with no manual clicks.
• Attribution: every forwarded item should still show who originally wrote it, so the recipient group can see the sender’s name exactly as WhatsApp reports it.

Acceptance criteria
– One-time setup where I enter the source and destination group IDs or QR codes.
– Continuous operation: if WhatsApp Web sessions expire, your tool should re-authenticate on its own or alert me.
– Latency should stay below a second for text and single-image posts under normal network conditions.
– Provide an installer (or simple folder drop) plus full source code and a concise README that explains configuration, dependencies and how to swap groups later.

Use any approach you prefer—WhatsApp Web automation (e.g., Selenium, Puppeteer), the yowsup library, or an official Cloud API wrapper—so long as it is stable and complies with WhatsApp’s current limits. I am ready to test immediately, and payment will be released when the above criteria are met and the tool runs reliably on my Windows machine.
