There's some alternatives, but its mostly due to the fact that kryptox is a nice consistency and doesn't separate.
Some alternatives include gazzew loop, certain superlubes, tribosys, some, very small amount of china aliexpress lubes. SW something it was I think. But generally krytox is just what you want.
For stab wires, dielectric grease, I use the super cheap silicone superlube one. Big ass tube for 3 bucks off amazon and it lasts forever.
