Engines #

Under the hood WAHA allows you to use different engines. You can control what you want to run by settings WHATSAPP_DEFAULT_ENGINE environment variables.

docker run -it -e "WHATSAPP_DEFAULT_ENGINE=WEBJS" devlikeapro/waha

If you have any problems with one engine - try another!

All engines are available in both Core and Plus versions.

WEBJS #

👉 Read more about WEBJS

WHATSAPP_DEFAULT_ENGINE=WEBJS

A WhatsApp API client that connects through the WhatsApp Web browser app. It uses Puppeteer to run a real instance of Whatsapp Web to avoid getting blocked.

NOWEB #

👉 Read more about NOWEB

WHATSAPP_DEFAULT_ENGINE=NOWEB

NOWEB engine does not require a browser to work with WhatsApp Web, it does so directly using a WebSocket. Not running Chromium saves you CPU and Memory, so you can run more instances on a single server!

Quotes from the users:

The server has 2 CPU and 8GB of memory. Today we have 85 sessions in this instance.

400 sessions with 4CPU and 32RAM. It’s working fine.

VENOM #
