Chatbase vs Botpress: which AI agent builder is cheaper per conversation, and which is easier?

Chatbase and Botpress both let you build an AI agent trained on your own content and put it on your website, WhatsApp and other channels. They price in different units, credits per reply against conversations, which makes them hard to compare. This guide converts both into a cost per conversation, using prices checked on 25 October 2026, and explains where each is the better tool.

What is the difference between Chatbase and Botpress?

Chatbase is a quick way to turn your website, documents and help content into an AI agent, with a few actions such as bookings or lookups. Botpress is a fuller platform for building agents with workflows, tables, code and many integrations. Chatbase is faster to launch; Botpress gives more control.

Both now include features beyond the agent itself. Chatbase's Basic plan adds a helpdesk inbox, voice and API access. Botpress offers Botpress Desk, an AI helpdesk, alongside its Studio builder. In practice, a non-technical owner can get Chatbase live in an afternoon, while Botpress rewards someone who will design flows and maintain them.

How do Chatbase and Botpress plans compare?

Chatbase's yearly billing takes 20% off; so does Botpress's. Chatbase's plan names changed during 2026, so older guides may call its middle plans Standard and Pro. Our separate Chatbase pricing and Botpress pricing guides cover each in more depth.

How do message credits and conversations differ?

A Chatbase message credit is spent each time the AI model is called, so a reply can cost 1 to 5 credits depending on the model, and an action can add a second call. A Botpress conversation is any exchange with at least two messages from the customer in a month, however many replies the agent sends.

• Chatbase credits per reply: Chatbase's FAQ lists 1 credit for its most economical models, 2 for a group of fast models, 4 for an advanced reasoning model and 5 for its deep-analysis model. If an action runs, such as checking calendar slots, the agent makes two model calls and uses twice the credits. Plan credits renew on the 1st of each calendar month and do not carry over; bought credits never expire.
• Botpress conversations: a conversation spanning two months counts in both, separate anonymous sessions count separately, and AI-only and human-assisted conversations count the same. Each conversation includes $0.10 of AI usage paid by Botpress; heavier AI use triggers $10 credit grants.

What does one conversation cost on each?

Assume a typical customer conversation gets four AI replies. On Chatbase that is 4 to 20 credits depending on the model. On Botpress it is one conversation.

For short conversations on economical models, Chatbase is clearly cheaper per conversation. Botpress catches up when conversations are long, when you use premium models heavily, or when you are inside its free 100 conversations. A worked month makes it concrete: a hypothetical clinic with 500 conversations of four replies on a 2-credit model uses 4,000 credits, exactly Chatbase Basic at $150, or $120 billed yearly. On Botpress Plus the same month is $150 plus three packs of 100 at $65, $345 billed yearly.

How does WhatsApp work on Chatbase and Botpress?

Both connect through Meta's official WhatsApp platform, and on both Meta bills message charges to your own Meta account. The agent's usage, credits or conversations, is counted on top.

• Chatbase includes WhatsApp on every plan. Its guide has you log in with Facebook, pick or create a WhatsApp Business profile and add a number, which then cannot be used in the WhatsApp or WhatsApp Business app at the same time unless you use Meta's coexistence option. It says you can send 1,000 free messages a month, then must add a payment method in Meta's billing settings.
• Botpress lists WhatsApp on Plus. Its documentation requires a Facebook business page and a WhatsApp Business Account, and Meta must verify your business before the bot can message users.

The 1,000 free messages match Meta's pricing since 1 October 2026: 1,000 free service messages per business number a month, then a per-message charge by country, with template messages charged on delivery.

Which gives you more control?

Should you choose Chatbase or Botpress?

Pick Chatbase if you want one agent live quickly from your website and documents, you are not a developer, your conversations are short, and you prefer a predictable credit allowance. Pick Botpress if you need custom workflows, several agents, structured data, deep integrations or a free plan to prototype on, and someone on the team can build and maintain it.

What about a finished WhatsApp agent?

Both tools are builders: you assemble the agent, then wire up booking, lead capture and WhatsApp yourself. A service business that wants all of that ready-made may prefer a finished product.

ReplyKit, which we make, is one. It answers WhatsApp and website chat from your website, PDFs, price lists and Q&A, qualifies leads into a simple hot, warm and cold list, and books into your real open slots with reminders, from $29 a month for 1,000 AI replies (plans). It counts replies, not credits, and has no Meta fees because it links to your number by QR code. That method is unofficial and not sanctioned by Meta, so a number can be restricted; we cap replies and recommend a dedicated number. It has no API, webhooks, Zapier or custom actions, so for those, Chatbase or Botpress is the better choice. Compare it in ReplyKit vs Chatbase, or start a 7-day free trial.
