I was curious since this is a different link than the main SilverBullet site (silverbullet.md). Looks like it's built by the same developer, but as a closed-source wrapping of the MIT licensed open source core of that project, as a desktop application.
It's definitely interesting. Though SilverBullet itself never stuck strongly with me - not enough to replace Obsidian anyways - I still run an instance because it's handy for quick notes. And doesn't rely on anything more than signing into a web site from whatever computer I happen to be using.
It could be a very nice addition to the personal notes space, though macOS only (at least for now) is very limiting.
