fdupes is great — until you can't install it. I built a zero-install duplicate finder.

fdupes, jdupes, rdfind, fclones — the duplicate-file finders are all excellent. They're also all native binaries you have to install first. Which is exactly what you can't do on the box that actually has the duplicate-file problem: the locked-down work laptop, the client's server, the CI runner, the throwaway container, the colleague's machine you're helping debug.

So I built duphunt: a duplicate finder that runs the second you have Node or Python, with nothing to install and no dependencies of its own.
