Depending on how deep you want to go down the rabbit hole, you could bridge WhatsApp to Matrix using the web client and whatsapp running in an emulator - https://www.matrix.org/blog/2019/02/26/bridging-matrix-with-...

Not a solution for even most people unless you're really into Matrix and running your own servers though. (I bridge WhatsApp, but use a physical phone to do so)

And then take it a step further with something building on matterbridge[1], which has libs to "bridge between mattermost, IRC, gitter, xmpp, slack, discord, telegram, rocketchat, steam, twitch, ssh-chat, zulip, whatsapp, keybase, matrix and more".
