From the download page on the website:
"Note: Little Snitch version 1.0.0 does not currently work with the Btrfs file system! Btrfs is used by default on Fedora, so Little Snitch does not currently identify processes on Fedora. We are working on an 1.0.1 release to fix the issue as soon as possible!"
Someone already created an issue for it: https://github.com/obdev/littlesnitch-linux/issues/1
I was looking for a comment like yours. Same issue, in my case only eating up half of my cores but with 100% utilization, webUI not working.
Your average Linux experience.
And the second most upvoted comment is someone seriously asking if 2026 if the year of Linux desktop...
Sorry, we have not tested on Fedora before release. Did not expect so much interest in the first hours after release...
I have now installed Fedora in a VM (ARM64 architecture, though) and it does load, but cannot identify processes. I'm investigating this now.
The other issue seems to be with eBPF compatibility. That's a moving target and I'll investigate next. But resources are limited, I'll need some time to dig into this.
