Is a WhatsApp Chatbot Free? What Is and What Is Not
A WhatsApp chatbot can be free only in limited forms. The free WhatsApp Business app sends automatic greeting and away messages and stores quick replies, but it cannot read a question and answer it. Chatbot builders often have free plans or trials with caps on messages or features. Building your own on Meta's Cloud API costs nothing to set up, and Meta gives each number 1,000 free replies a month, but you pay for hosting, the AI model if you use one, replies beyond the first 1,000, and any template messages you send. A chatbot that answers real questions for a real business always costs something, in money or in your time.

|---|---|---|
| WhatsApp Business app | Greeting message, away message, quick replies, catalogue | Read a question and answer it |
| Chatbot builder free plan or trial | A limited number of messages, contacts or days | Run for long or at volume without paying |
| Build your own on the Cloud API | Meta access, and 1,000 replies per number each month | Run without hosting, a developer and, for AI, model fees |
| Bulk-sending "free bots" on the normal app | Nothing to pay upfront | Stay inside WhatsApp's rules; automated and bulk messaging on the normal app is not allowed |
Can you make a WhatsApp chatbot for free yourself?
Yes, if you can code. Meta's Cloud API is free to use, a developer can receive messages on a free hosting tier, and the first 1,000 replies per number each month cost nothing from Meta. A simple keyword bot with modest traffic can run like this for close to zero.
An AI chatbot changes the maths. Every reply sends the conversation to a language model, and model providers charge per use. The cost per reply is small, but it is never zero, and someone has to keep the code running, update the business information and fix problems. "Free" here means you pay in hours instead of money.
What costs appear once a chatbot answers for your business?
- The software or builder. Monthly plans are the norm once you pass a free tier.
- AI model usage. For AI chatbots, charged by the provider or included in the plan.
- Meta message fees. Since 1 October 2026, replies beyond 1,000 per number each month, reminders, updates and promotions are paid per message, by country and type.
- Your time. Writing the business information, testing replies, reading conversations.
When a price list says "free chatbot", ask three questions: free for how many messages, free for how long, and who pays Meta's fees.
Is a free trial a better test than a free plan?
For an AI chatbot, a short trial with your real customers usually tells you more than a long free plan with heavy limits. What you need to learn is whether it answers your customers correctly, and that shows in the first few dozen real conversations.
CertuAI, for example, starts every new account with a trial of 50 customer messages within 7 days, whichever comes first, with no card; after that, paid plans start at US$ 75 a month. Whichever tool you try, use the trial on real conversations, not on test questions you invent.
How do you test a free WhatsApp chatbot properly?
- Write down the ten questions you get most, in your customers' own words.
- Ask each one through WhatsApp, the way a customer would.
- Check every price, time and address in the answers against the truth.
- Ask something it cannot know and see whether it admits it or invents.
- Ask for a person and time how long the hand-over takes.
- Read the limits of the free plan: what happens on the day you hit them.
When is paying for a WhatsApp chatbot not worth it?
If you get a few messages a day and answer them yourself within minutes, the free app's greeting and quick replies are enough. Paying makes sense when messages arrive faster than people can answer, when they arrive outside working hours, or when the same questions take hours of someone's day.

Frequently asked questions
- Is there a completely free WhatsApp chatbot?
- Not one that answers real questions without limits. The WhatsApp Business app's automatic messages are free but fixed. Builder free plans are limited. A self-built bot costs hosting, time and, for AI, model fees.
- Does WhatsApp charge for chatbots?
- Meta does not charge for having a chatbot. On the WhatsApp Business Platform it charges per message: since 1 October 2026 that includes replies beyond the first 1,000 per number each month, plus every template.
- Is the WhatsApp Business app chatbot free?
- The app's greeting and away messages are free. They send the same text to everyone and do not answer questions, so they are auto-replies rather than a chatbot.
- Are free WhatsApp bots safe?
- Tools that automate the normal WhatsApp app to send bulk messages break WhatsApp's Terms of Service and put the number at risk. Check what a free tool does with your number before you scan any QR code.
