Botpress is a developer-grade platform for LLM-powered agents — genuinely powerful, with a studio, knowledge bases and AI-token-based billing. But if what you need is a reliable WhatsApp bot with menus, FAQs and bookings, that power turns into overhead. FlowBot keeps it deterministic, visual and free.
| FlowBot | Botpress | |
|---|---|---|
| Learning curve | Minutes — drag, wire, test | Hours — studio, nodes, knowledge bases |
| Runtime model | Deterministic flowchart (AI only if you add it) | LLM-agent centric |
| Billing | Free — provider message costs only | Free tier, then usage/AI-token based |
| Own / export the code | Yes — Node.js ZIP | Partially (open-source roots, cloud features differ) |
| WhatsApp setup | Four providers, guided activation | Via channel integrations |
| Best at | Free predictable WhatsApp bots | Complex AI agents, developer extensibility |

Deterministic first, AI when you choose
FlowBot's engine runs exactly the flowchart you drew — a menu is a menu, a booking is a booking, and nothing improvises in front of customers. When you do want an AI moment (a support Q&A block, say), you drop in an AI Reply block with your own LLM key, scoped to that block. No token packages, no agent unpredictability, and the whole bot still exports as plain Node.js.
Where FlowBot is not the answer
FlowBot is a free builder for the bot itself. It includes a live inbox with human takeover, per-block funnel analytics and simple broadcasts — but not a multi-agent team inbox with assignment rules, a full campaign manager, or official Business Solution Provider (BSP) onboarding and support. You bring your own WhatsApp provider (Meta Cloud API, Twilio, Green API or Whapi.cloud). If you specifically need an all-in-one managed platform with agent teams, campaign tooling and hand-holding, a paid provider can be worth the money. If you want to build and own the bot logic for free, that's exactly what FlowBot is for.
Botpress is the right call for teams building sophisticated AI agents with custom code, integrations and knowledge retrieval. For a free WhatsApp bot that behaves the same every time, use FlowBot.

Frequently asked questions
How is FlowBot different from Botpress?
Botpress centres on LLM agents and developer tooling with usage-based billing; FlowBot centres on a free deterministic flowchart where AI is an optional block using your own key. Simpler to learn, predictable in production, and the code exports.
Can FlowBot do AI answers like Botpress?
Yes, scoped: the AI Reply block (or an AI step inside a custom block) chats with your own Anthropic/OpenAI/Gemini key until the customer returns to the flow. The rest of the bot stays deterministic.
Who should pick Botpress instead?
Developer teams building complex agents — RAG over documents, custom actions in code, multi-step reasoning. That's Botpress's home turf; FlowBot deliberately stays simpler.
