Hello @pform, welcome to our forums!
You can use etcher to flash one or many devices simultaneously in any environment but you’ll need to have enough available ports in your computer or complement with external hubs.
etcherPro was designed exactly for your use case, flashing many devices simultaneously at high speeds in a production environment. We’ve recently announced that we’ll be starting pre-orders on January 5th, so I’d suggest you stay tuned to the updates in this thread.
Cheers,
Nico.
