heyoo vs wa-js
WhatsApp integrations for Python and JavaScript compared
heyoo wraps the WhatsApp Cloud API for Python apps that send messages and handle webhook data. wa-js exposes WhatsApp Web functions to JavaScript integrations running in the browser, so the projects differ in both platform and integration approach.

heyoo: Connect Python Apps to WhatsApp Cloud API
heyoo is an unofficial Python wrapper for WhatsApp Cloud API, covering message sending and webhook payload handling. It suits Python developers building WhatsApp messaging or support workflows who want a library-level interface instead of assembling API requests themselves.

wa-js: Access WhatsApp Web Functions from TypeScript
WA-JS exposes WhatsApp Web functions through a JavaScript API for browser-based integrations and automation. It is actively maintained and suits developers who can run code in a WhatsApp Web session and adapt to changes in the web client.
