WhatsMax | AI Omnichannel Marketing, Automation and Chatbot SaaS NodeJS Script

What you are buying — a one-time purchase of the complete, self-hosted WhatsMax source code (Next.js / Node.js). You install it on your own VPS, run it under your own brand and keep 100% of what you charge your customers. There is no monthly platform fee from us and no user limit in the script.

Third-party costs — WhatsMax connects to services you sign up for yourself, and those providers bill you directly: WhatsApp Cloud API / Meta (conversation pricing), AI providers (OpenAI, Anthropic Claude, Google Gemini token usage), SMS providers (per message), payment gateways (transaction fees), SMTP / email, optional Pusher for realtime and optional S3-compatible storage. All of them are pay-as-you-go and optional until you switch that feature on — WhatsMax itself never charges you again.

Where it runs — WhatsMax is a Node.js application. It needs a VPS or cloud server with Node.js 20+, MySQL 8+ and Redis. It does not run on classic shared cPanel/PHP hosting. Installation is documented step by step.
