Reminds me of yesterday's hn post about making your PDFs look scanned by... Uploading to a web server that runs a ghostscript command.
It's almost as if locally running software is deeply confusing to people and the perception is that you need to have a potentially privacy violating service if you have a friendly ui. Not to mention all the energy wasted running those servers. Is this how bad our society has gotten at writing software?
They can't easily run ghostscript directly, and making a web service is easier than making an app (recompiling ghostscript for all CPU architectures, ...) despite the ongoing hosting costs.
That is also in addition to sending your documents to who knows who.
You can probably compile ghostscript to javascript via emscripten or similar. I am not sure what this means for its AGPL license.
But maybe this is more a discussion for that other thread.
Shouldn't be any "worse" than running it server-side, since AGPL exists in order to apply to SaaS.
The site will provide you with a root password for your embedded device, and you will provide the site with the wifi network and credentials needed to access the network where the device is.
That doesn't sound like good security practice.
