A WhatsApp flow builder that doesn't trap your customer at step three.
Drag-and-drop flow builders are everywhere. Most of them turn into mazes the customer can't exit. Waaru's flow builder pairs 21 node types with AI fallback on every node — so when a customer goes off-script, the AI handles the detour and the flow resumes at the right place.
In one line
A WhatsApp flow builder is a visual editor for designing automated WhatsApp conversations: message nodes, branches, forms, API calls, payment links, and handoffs. Waaru's flow builder adds AI fallback on every node so off-script messages don't dead-end the conversation.
No credit card. No commitment.

The problem
Why most WhatsApp flow builders quietly lose 30% of conversations.
Open any other WhatsApp platform's flow builder, configure a five-node flow, and test what happens when the customer types something you didn't predict. You'll get a fallback message, a loop back to 'main menu', or silence. The conversation is over and the customer doesn't tell you why they left.
No-match branches default to a generic 'sorry, I didn't understand' reply.
Editing a published flow is destructive — there is no version history or rollback.
WhatsApp Native Flows (in-chat forms) are rarely supported, so structured data still requires a redirect to a web form.
Conditional branching is shallow — handling 'maybe' answers usually requires duplicating the flow.
Chapter 01
21 node types covering every real WhatsApp moment.
The flow builder ships a node for every action you'd actually need.
WhatsApp Native Flows — in-chat forms (Meta's WabaFlow)
Branch — conditional routing on variables or AI intent
API call — REST request with typed response handling
Payment link — Razorpay or any payment gateway
Catalog — show a product catalog directly in chat
Wait — delay or wait for a specific event
Tag, score, and segment contacts
Handoff — escalate to human inbox with summary
AI fallback — automatic on every other node
Chapter 02
AI fallback on every node, automatic.
Every Waaru flow node has a built-in AI fallback. When a customer's reply doesn't match any expected branch, the AI takes the message, answers from your Company Brain, and steers the customer back to the flow at the right point. You don't configure this. It's on by default.
This is the single feature that separates a flow that runs in a demo from a flow that runs in production. Customers are not predictable. Your flow shouldn't pretend they are.
Chapter 03
Native WhatsApp Flows for structured data.
Meta's WhatsApp Flows let you present a structured screen — name, phone, date picker, dropdown, multi-select, image upload — directly inside the chat window, with no browser redirect. Completion rates run 2–3x web link redirects.
Waaru supports WhatsApp Flows as a first-class node. Build the form in the dashboard, submit it for Meta approval, and drop it into any flow. The submitted answers come back as variables you can use anywhere downstream.
Chapter 04
Versioned, rollback-safe, A/B-testable.
Every flow publish is a versioned snapshot. You can compare versions, see exactly what changed, and roll back if a new version under-performs. Production flows can be split-tested — run version A on half of traffic and version B on the other half, see which converts better, promote the winner.
Chapter 05
Pre-built templates for the common D2C, hospitality, and lead-gen flows.
The flow library ships with templates that work out of the box: abandoned cart, COD verification, order tracking, post-purchase review, hotel booking, site-visit scheduling, lead qualification, NPS survey. Clone a template, point it at your knowledge base, ship it. Most templates go live in under 20 minutes.
