Orion for Linux
I wouldn't be able to tip 100$ but I would tip in time to time to keep supporting it, or I could just sub to plus.
I'd 100% chip in for a Linux version! <3
For developing a browser on Linux, I highly recommend considering Igalia. They are an open source consultancy with extensive experience in browser technologies. Notably, they developed WPE WebKit, an optimized version of WebKit for embedded systems. Their expertise in web engines and contributions to major browser projects make them an excellent choice for your Linux browser development needs.
If you contact them you can get an estimated budget to give you an idea of how much it might cost to create a version of Orion for Linux.

Vlad I would.
I would encourage reaching out to Gnome directly to ask if they would be interested in helping out with this effort (https://foundation.gnome.org/contact-us/).
There is also https://www.sovereigntechfund.de/ which have sponsored lots of work on FOSS projects the last year or so. They might be interested in Orion.

clintre Only 7 people out of 85 say they would chip in for a kickstarter, and this is the hard core userbase we are talking about here. That does not give a lot of confidence to go in and spend significant resources setting it up. We will focus on Mac for the time being and start thinking about Linux version when opportunity shows (will be triggered by either growth of Orion paid members or Kagi paid members)
that's a bummer 
I would use Orion for Linux as long as it doesn't use anything that starts with Chrom....
As far as a Kickstarter goes, I guess it just depends on the timing and if there was going to be a completely new engine or not.. Latching onto https://servo.org would be a win IMHO.
It is a bummer that this doesn't look like it is going to happen. Actually started using Kagi to hopefully help fund things like this. Probably time to move on, but totally understand from a business perspective.
geeknik Servo looks interesting and I like the idea. However, may be early for production/paid software. I tried it on my Mac and it couldn't pass all BrowserBench tests. Then it was substantially slower than Orion on the ones it could do (e.g. JetStream2). Seems like it will need more time to bake before it is ready.
In an ideal world, Orion could virtualize the interface to the web engine such that either WebKit or Servo could be used and perhaps available as a platform/version build decision. However, not sure that would be like trying to develop an airframe that could accept both propeller and jet engines. In theory possible but the result not really good as either. Vlad et all know the architectures and issues best, but I could see why they decide to stick with WebKit for the forseeable versions.
I'm interested, Kagi unlimited user. I'd be interested in buying a lifetime Orion license if it whad Linux support, but since the Mac and iOS apps don't have many worthwhile extras and i have to use a different browser on Linux, i'll stick with just my Kagi sub for now. I'd also be interested in supporting a kickstarter, but i do recognize the challenge in realizing enough support to make it happen.
