If bundling your devDependencies at compile time counts as "0 dependencies", nothing has any dependencies. In this case, the whole thing's built on electron - all of chrome's rendering engine is quite the dependency. The uncompressed Windows version is 137 MB on disk. Fatter than most any app should be.
I would not suggest this as KeePassXC does not support the new KDBX4 format with the upgraded cryptography - only the old Keepass format which relies on a custom AES-based key derivation function, which I cannot in good faith recommend.
Once it's implemented I may reconsider, but for now at least, I'd shy away from it.
Also mutiplatform as KeePassXC, built on Electron. Even though it is built on JavaScript, it has 0 dependencies[1].
And the author responds well on external feedback/contributions[2].
It does support KDBX4[3].
