Looking for recommendations on how to SMS from a computer, á la Pushbullet or some such. Currently using Google Messages with companion desktop/web app and love the experience, but am on a de-Googling quest and looking for alternatives.

Prefer FOSS options (love the Fossify stuff, for example) but an willing to pay a slight premium if required. Would like solution to be compatible with any web browser and Windows but Linux (Mint) would work, too.

Any suggestions are welcome. Thanks in advance!
