Floppy is a fork of Yamtrack that seems to have only recently gotten its own name. From the notes on that release (emphasis mine):

I’m still not a professional developer; I’m an enthusiastic maintainer using AI coding tools to build the media tracker I want to use. Floppy is now a standalone project based on the incredible work of FuzzyGrim/Yamtrack, independently maintained and supported by @dannyvfilms. Yamtrack import and documented compatibility paths remain supported, but users install Floppy directly rather than treating an upstream container replacement as a migration plan.
