WhatsApp calling is live — answer customer calls right inside your inbox.

Comparison

Instant vs MSG91

These are not quite the same kind of product, and the honest comparison starts there. MSG91 is a communication API platform — WhatsApp sits alongside SMS, email and voice, and you build the interface. Instant is the finished thing: an inbox your team logs into, with AI, campaigns and a pipeline already in it.

Choose Instant when
  • You want software your team opens tomorrow, not an API to build against.
  • The inbox, the AI and the pipeline should be one product with one bill.
  • You want to see what it costs and what is included without a sales call.
Choose MSG91 when
  • You are a developer wiring WhatsApp into your own product, and the interface is yours to build.
  • You need SMS, email and voice on the same account as WhatsApp — Instant is WhatsApp, Instagram and Messenger only.
  • You want the lowest possible platform fee and do not need a CRM on top of it.
