When to use Evolution API
Honestly: Evolution API makes sense if you want full control, have your own infrastructure, and are building something experimental or internal. If you are a dev who wants to learn how things work under the hood — go for it. It is a good project.
When to use Wapper
Wapper makes sense when WhatsApp is part of your product — not an experiment. When your client cannot wait for you to reconnect. When you do not want to be woken up to reconnect. When a banned number means a lost client.
The elephant in the room
The unofficial WhatsApp API violates Meta's Terms of Service. This means Meta can ban your number without prior notice, without appeal, without refund. It happens. Frequently. Usually at the worst possible moment.
