WasenderAPI alternative: how Threadwire compares
WasenderAPI and Threadwire both link the WhatsApp number you already use by QR code and give your system an API to it. Both are unofficial, and both say so. WasenderAPI is the lowest-priced service we compared; Threadwire enforces how a number sends.

Sending safety
WasenderAPI offers "Account protection" as a setting on each session. With it on, sending is limited to one request every 5 seconds. With it off, a paid plan may send 256 requests a minute with no daily cap. Its help pages advise far less: two messages a minute, and a reply from 30% of recipients.
Threadwire has no setting that turns protection off. The pace depends on who the message goes to, new people are limited each day, and new chats slow down, then pause, when WhatsApp warns the number. How Threadwire keeps your number safe has every rule.
