ReplyKit vs Gupshup: a ready-made AI agent for one business, or a conversation platform for building at scale?

Gupshup and ReplyKit both put AI on WhatsApp, but they are different kinds of product. Gupshup is an enterprise conversation platform (a CPaaS) with WhatsApp, SMS, RCS and Instagram, APIs and AI agents for large brands. ReplyKit is a finished AI agent for a small business's WhatsApp and website. This page explains the gap fairly, with Gupshup's published prices.

Is Gupshup a chatbot or a messaging platform?

Gupshup is a messaging platform first. It describes itself as a conversational AI platform for marketing, commerce and support, and says it handles about 120 billion messages a year for more than 50,000 customers, with over 20 years in the business (its own figures). It sells the WhatsApp Business API, SMS, RCS and Instagram messaging, campaign tools, and AI products including AI agents, an AI co-pilot for human agents, its own fine-tuned ACE LLM model, and an "Avatar Agent" for websites.

ReplyKit is a much smaller, narrower product: an AI agent that answers WhatsApp and website chat for a small business from its own content, qualifies leads, books appointments and hands over to a person. It has no SMS, no RCS, no Instagram and no campaigns. We make ReplyKit, so weigh our view accordingly; this page tries to show where each one genuinely wins.

What does Gupshup charge for WhatsApp messages?

On its self-serve WhatsApp API plan, Gupshup charges a flat $0.001 per message on top of Meta's per-message fees, which it bills at Meta's rates. Its enterprise features and pricing are handled through sales.

Two things to notice. Gupshup's fee applies to incoming session messages too, so a customer's message to you costs $0.001 as well as your reply. And the price covers messaging, not a finished AI agent: on self-serve you get the API and tools, and you or a developer build the conversation logic, or you talk to Gupshup's sales team about its AI agents.

What does it cost to answer 2,500 enquiries a month on each?

Take a hypothetical clinic in India that gets 2,500 customer messages a month, sends 2,500 replies and 400 appointment reminders. Meta's India rates from 1 October 2026 are $0.0014 per utility or service message, with 1,000 free service messages per number each month.

So Gupshup's messaging is cheaper, by a lot. Whether the whole thing is cheaper depends on who builds and runs the agent. A company with a developer who can wire an AI model to the API, handle bookings and maintain it will spend less per month on Gupshup. A clinic owner without a developer will spend far more in time or in an agency's fees. Our ReplyKit vs Twilio page walks through the same build-or-buy decision in more detail.

How do Gupshup and ReplyKit compare across channels, AI and setup?

Both products also reach your website. Gupshup's newest offer is an "Avatar Agent", an AI assistant with a talking face that it says goes live with one line of code. ReplyKit's website assistant is plainer: a chat widget, added with one line of code, with its own instructions and knowledge, drawing on the same reply allowance as WhatsApp. If a branded avatar matters to you, Gupshup has something we do not. If you want the website and WhatsApp to give the same answers from the same knowledge with nothing extra to configure, ReplyKit is simpler. Our guide to website chat versus a WhatsApp agent covers when you need both.

When is Gupshup the stronger choice?

• You operate at scale. Banks, telcos, retailers and marketplaces sending order updates, OTPs and campaigns to hundreds of thousands of customers need the official API, throughput and enterprise support. That is Gupshup's home ground.
• You need several channels. If you want SMS fallback, RCS or Instagram in the same platform, Gupshup has them; ReplyKit does not. See our RCS vs WhatsApp guide for when RCS matters.
• You have developers. At $0.001 a message, a technical team can build exactly the flows it wants for very little platform cost.
• You cannot accept number risk. The official API is sanctioned by Meta. A QR-paired tool is not.
• You want a green tick or templates. Both require the API.

When is ReplyKit the stronger choice?

• You have no developer and no time. ReplyKit learns from your website, PDFs, price lists and Q&A pairs, and is answering within about 15 minutes. No templates, no business verification, no sales call.
• Your job is answering and booking. The agent qualifies leads (name, need, budget, timing), scores them hot, warm or cold, and books real open slots with double-booking protection.
• You want a predictable bill. A flat $29, $49 or $99 a month with AI included, no Meta fees, and $10 packs of 1,000 extra replies that never expire. See the plans.
• You want the AI to stay honest. It answers only from your knowledge, says so when it does not know, and lists the question so you can teach the answer once.

The trade-off, stated plainly: Quick Connect is an unofficial QR pairing, not the API, and a number can be restricted. You see one plain notice before connecting; pressing Connect accepts section 3 of our Terms. We cap replies (by default 30 an hour and 200 a day, with a warm-up) and recommend a dedicated number.

What should you ask before choosing either?

1. Do we send, or do we answer? Campaigns, OTPs and order updates need the official API. Answering inbound questions does not.
2. Who will build and maintain the AI? If the answer is "nobody", a platform priced per message is only the start of the cost.
3. What is our real monthly volume? Count incoming and outgoing messages, because Gupshup's fee applies to both.
4. How much risk can our number take? If losing the number for a week would hurt badly, use the API.
5. Do we need other channels? SMS, RCS or Instagram point to a CPaaS. WhatsApp and website only point to an agent like ReplyKit.
