The differences in detail
Green API is an unofficial WhatsApp gateway with carefully written technical documentation, widely used by developers to integrate messages. Whaiz works on the same ground — personal number, REST, webhooks — but shifts the value to the AI layer: a conversation handled by the bot with a per-chat persona, voice and media, instead of transport alone.
The choice depends on what you want to manage. With Green API you get the endpoints and build the intelligence on top; with Whaiz the AI is already included and configurable without code. Green API's pricing is usage-based per instance, while Whaiz's is a euro rate that includes the AI. Like the others, both use a personal number: no Meta approval, but the ban risk still has to be managed.
