Green-API alternative: how Threadwire compares
Green-API and Threadwire both link the WhatsApp number you already use as a device, without Meta's approval, and give your system an API to it. Green-API also sells Meta's official API as a separate product. Green-API is priced low and built for developers; Threadwire enforces how a number sends, and adds a panel for your team.

Sending safety
Green-API gives you a queue with a delay you choose, and advice: 15 seconds between messages, no more than 200 customers a day, ten days of warm-up, and half of your recipients answering. When WhatsApp restricts a number, the instance shows a "suspended" status, and messages to people it has not talked to fail.
Threadwire does not leave these to a setting. The pace, the daily limit on new people and the warm-up are enforced on every number. A message that cannot go safely waits or is refused, with the reason. How Threadwire keeps your number safe has every rule.
