ReplyKit vs Chatfuel: a contact-priced chatbot builder for Messenger, Instagram and WhatsApp against a flat-price WhatsApp AI agent
Chatfuel was one of the first Messenger bot builders and now sells AI-powered plans across Messenger, Instagram and WhatsApp, priced by the number of contacts. ReplyKit is a WhatsApp and website AI agent priced by plan. The pricing model is the biggest practical difference, so we start there.
Quick answer
Choose Chatfuel if you need one AI bot across Messenger, Instagram and WhatsApp and your contact list is small; plans start at about $39 a month for around 150 contacts and about $69 for 500, rising steeply with volume, with no free plan and Meta's fees on WhatsApp. Choose ReplyKit if WhatsApp and your website are the channels and you want a flat price with AI replies included, official platform, booking and a CRM, from $29 for 1,000 replies a month. ReplyKit is $29, $49 or $99 a month with AI replies included (1,000, 5,000 or 20,000 a month), connected through Meta's official WhatsApp Business Platform with no pairing risk, a website assistant, booking, a CRM and inbox, and a 7-day free trial with no card. Meta's per-message fees apply only to reminder and follow-up templates sent outside the 24-hour window.

How contact pricing scales
Contact-based pricing is cheap at the start and expensive as you succeed. A business that talks to 150 people a month pays the entry tier; the same business at 1,500 contacts is several tiers up, and at 5,000 contacts the public tiers run to a few hundred dollars a month, before Meta's WhatsApp fees. ReplyKit counts replies, not contacts: 1,000 AI replies on Starter covers roughly 300 to 500 conversations a month for a typical service business, and the next plan is $49 for 5,000. Chatfuel's tiers are on its pricing page.
Where Chatfuel wins
- Three channels in one builder if Messenger and Instagram matter.
- A mature flow builder for structured journeys.
- Official API with no restriction risk on WhatsApp.
- Small lists pay less at the entry tier than they would for a broader tool.
Where ReplyKit wins
- Predictable cost that does not rise because more customers messaged you.
- Meta fees only on templates.
- Knowledge-first AI: paste the website, upload the price list, done; see what is a knowledge base.
- Booking, CRM and a Monday digest for service businesses.
Where the connection matters: ReplyKit runs on Meta's official WhatsApp Business Platform, so there is no linked-device pairing and no restriction risk from automation. Meta's per-message fees apply only to reminder and follow-up templates sent outside the 24-hour window; replies to customers who message you carry no Meta fee inside it. The trade-offs are explained in why ReplyKit runs on the official platform.
ReplyKit plans: Starter $29 (1 number, 1 agent, 1 website assistant, 1,000 replies), Growth $49 (3 numbers, 5 agents, 5 website assistants, 5,000 replies, follow-up nudges), Pro $99 (15 numbers, unlimited agents, 20,000 replies). Extra replies are $10 per 1,000. AI is included, and Meta's message fees apply only to reminder and follow-up templates. Details in what it costs.
