👋 Hey DEV Community! Have you ever tried setting up a WhatsApp CRM for your startup, agency, or side project? If you have, you’ve probably hit the grim reality of the current WhatsApp SaaS ecosystem: 💸 Insane Seat-Based Pricing: Paying $50 to $150 per agent per month just to let a couple of teamm

Have you ever tried setting up a WhatsApp CRM for your startup, agency, or side project?
If you have, you’ve probably hit the grim reality of the current WhatsApp SaaS ecosystem:
I got tired of these artificial barriers. So I decided to build OpenWAB — a lightweight, 100% self-hostable WhatsApp CRM powered by a Universal Multi-Provider AI Engine.
And the best part? Zero software subscription fees. Zero seat pricing. No middlemen. You only pay Meta’s raw API charges directly to Meta.
I’m preparing to launch OpenWAB as a premier open-source project, and I’m looking for passionate developers, UI/UX designers, and open-source contributors to help build the future of WhatsApp automation! 🤝
OpenWAB is a production-grade, self-hosted WhatsApp CRM designed from day one to run on ultra-affordable infrastructure (strictly engineered to run under a ~510 MB active RAM budget on a standard $5/month VPS).
It connects directly to the official Meta WhatsApp Cloud API, avoiding unofficial web scrapers, QR code hacks, and risk-prone reverse-engineered protocols.
