The differences in detail
The main difference isn't just price. UltraMsg is a transport layer: it gives you the endpoints to send and receive messages from a personal number, but you write the reply logic yourself. Whaiz starts from the same REST transport and adds a ready-made conversational AI on top, with a configurable persona per chat, voice and media handling and a queued anti-ban. In practice, with UltraMsg you build the bot; with Whaiz you configure it.
On cost, UltraMsg is billed per instance (around $39/month) and the bill grows with the numbers you connect; Whaiz has a euro rate (€15/month for the first number, €5 for each extra one) that includes the AI. To be honest, both use a personal WhatsApp number via an unofficial library: neither one fully removes the risk of restrictions from Meta, and both require reconnecting the phone periodically, like WhatsApp Web.
