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.

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

Sell your own messaging SaaS instead of paying for one. WhatsMax is a production-ready, multi-tenant platform that puts WhatsApp, WhatsApp QR, Facebook Messenger, Instagram DM, Telegram, WeChat, SMS and email into one shared team inbox — then adds bulk campaigns, a drag-and-drop automation builder, AI chatbots grounded in your own documents, a social media planner, e-commerce sync, a lead CRM and subscription billing through 13 payment gateways. Launch it as a SaaS for paying tenants, or run it in-house for your own brand.

Omnichannel team inbox

• One shared inbox for WhatsApp Cloud API, WhatsApp QR (Baileys), Facebook Messenger, Instagram DM, Telegram, WeChat, SMS and email

Server requirements

• Node.js 20 LTS or newer (22 LTS recommended)
• MySQL 8.0+ (MariaDB 10.6+ works) — Prisma ORM
• Redis 6+ — required for queues, scheduling and caching
• Nginx (or Apache) reverse proxy and an SSL certificate — mandatory, Meta webhooks require HTTPS
• Recommended VPS: 2 vCPU / 4 GB RAM, Ubuntu 22.04 or 24.04 LTS
• A server that can run long-running background processes. Besides the web process, WhatsMax needs a queue worker kept alive by PM2 and a scheduler tick run from cron every minute. Campaigns, automations, AI replies, scheduled posts and store syncs are executed there — not during the HTTP request — so a host that can only serve web requests cannot run this application
• Shared cPanel / PHP hosting is not supported — you need SSH and the ability to keep Node.js processes running

Tech stack: Next.js 16 · React 19 · TypeScript · Tailwind CSS 4 · shadcn/ui · Prisma (MySQL) · BullMQ (Redis) · Auth.js · PM2

On the roadmap

Chat agent Flutter mobile app — coming soon

• Native iOS and Android agent app built with Flutter, on top of the same WhatsMax REST API
• The shared inbox on mobile — assigned, unassigned and resolved views with unread counters
• Push notifications for new and assigned conversations
• Reply with canned replies, media and WhatsApp templates; assign, label, note and resolve on the go
• One Flutter codebase for both App Store and Play Store

AI calling — coming soon

• Inbound AI receptionist — answers calls, qualifies the caller and routes to a human agent
• Outbound AI calls triggered from automations: cart recovery, reminders and follow-ups
• Grounded in the same knowledge bases your chatbots already use
• Transcripts and recordings saved onto the contact timeline
• Call reports — duration, outcome and AI cost per workspace

Please note: roadmap features are in development and are not part of the current version of this item. Buy WhatsMax for what it does today — the feature list above this section. Voice-provider usage for AI calling will be billed by that provider.

Quick FAQ

Can I sell subscriptions with this? Yes — plans, trials, coupons, tax rates, invoices and 13 gateways are built in. Can I run it on shared hosting? No. It is a Node.js app and needs a VPS with SSH, Node 20+, MySQL and Redis. Is WhatsApp Business API approval required? For the official Cloud API channel, yes — you use your own Meta app. The WhatsApp QR channel works without Meta approval. What is the catch with the WhatsApp QR channel? It links a real WhatsApp account as a companion device using a protocol Meta does not sanction, so the number can be banned — it ships disabled by default, behind an acknowledgement screen and a separate gateway process. It also needs one extra install step (npm run gateway:install), because the library it uses depends on GPL-3.0 code that is deliberately not bundled. Every other channel is official API. Do I pay you monthly? No. One purchase, self-hosted. You only pay the third-party providers you choose to use. Is the code encrypted? No. Full, readable TypeScript source. Can I white-label it? Yes — name, logo and brand colours per client, from the admin panel.

WhatsMax is a self-hosted script, not a hosted service. WhatsApp/Meta, AI, SMS, gateway and email usage is billed by those providers, not by us.
