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.

Why buyers choose WhatsMax

• 8 channels in one inbox — most scripts stop at WhatsApp. WhatsMax adds Messenger, Instagram, Telegram, WeChat, SMS, email and a website chat widget.
• Everything is included — no paid add-ons, no locked modules, no “pro” version. Every integration below ships in the source you download.
• Built to be sold — plans, trials, coupons, tax rates, invoices, 13 gateways, per-client white label and a full super-admin panel.
• Modern stack, clean code — Next.js 16, React 19, TypeScript, Prisma, Tailwind CSS 4. Unminified, un-encoded, fully typed.
• AI where it pays off — chatbots with RAG over your documents, AI auto-replies, AI-generated automations and AI lead extraction.

Omnichannel team inbox

• One shared inbox for WhatsApp Cloud API, WhatsApp QR (Baileys), Facebook Messenger, Instagram DM, Telegram, WeChat, SMS and email
• Conversation assignment, labels, internal notes and open / snoozed / resolved states
• Canned replies, WhatsApp template sending and media messages from the composer
• Contact side panel — attributes, tags, marketing consent, orders and full cross-channel history
• AI ↔ human handover per conversation, unread counters and realtime updates via Pusher
• Guided channel setup screens — connect a channel by pasting credentials, no code

Campaigns & broadcasting

• Bulk WhatsApp template, SMS and email campaigns to saved segments
• Segments from tags, attributes, channel and activity — reusable in campaigns and automations
• CSV import, custom fields, tags, and opt-in / consent tracking
• Per-campaign delivery funnel: queued → sent → delivered → read → failed
• 15 SMS providers and per-workspace SMTP, all configurable by the tenant
• Sends run on Redis-backed queue workers, so a 50,000-contact broadcast never blocks the app

Visual automation builder

• Drag-and-drop canvas with triggers, conditions, delays, actions and sub-flows
• Triggers: inbound message, keyword, contact created, tag added, incoming webhook, campaign sent, order placed / fulfilled / cancelled, abandoned cart, lead stage changed

• AI flow generation — describe the workflow in one sentence and get a ready-made flow
• Run logs, run counters and pause / resume per automation

AI chatbots & knowledge bases (RAG)

• Build bots on OpenAI, Anthropic Claude or Google Gemini — bring your own API keys
• Knowledge bases with RAG — upload documents, automatic chunking and embeddings

• Token and cost tracking per workspace plus a cross-tenant AI usage report for you

Social media planner

Platform highlights

• True multi-tenancy — workspaces with their own channels, data, team, roles and plan limits; every query is workspace-scoped
• White label — per-client logo, app name and brand colours that flow through the entire theme
• Security — two-factor authentication (TOTP) with recovery codes, magic-link login, password reset, granular admin roles & permissions, audit log and GDPR data export
• Multi-language & multi-currency — translation manager in the admin panel, per-user locale, RTL-friendly UI
• Dark mode across the client app, admin panel and marketing site
• PWA & web push — installable app and VAPID push notifications for agents
• Developer tools — token-authenticated REST API, in-app API documentation, outgoing webhooks with delivery logs, media library
• Marketing site included — landing page, pricing page and CMS pages you can edit from the admin panel
• Reports for inbox, campaigns, automations, AI usage and social performance
• Background jobs — BullMQ worker and scheduler processes with a queue monitor in the admin panel

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.
