Make an account on MBin instance and use Interstellar.

Other than Fedilab, Flare can run Mastodon, Missky, Bluesky and X. Sadly it doesn't support Lemmy yet.

Piefed.social works for me but I don't know enough to be confident this makes sense. I stopped trying to make sense of the world decades ago, but that's what I use.

Hubzilla?

There isn't a universal one. A fun fact is that Activity pub, the protocol that lets these applications communicate on the backend, also has a front-end spec for this exact purpose, but no one has implemented it.

I would like one that each platform have it's own feed

with a single account (isn't that the point of the fediverse?).

Absolutely not. I'm not sure why people see Lemmy, Mastodon, Pixelfed, Peertube, Loops, etc as all the same thing that should all be one app.

They might communicate with the same protocol, but they have vastly different uses, interfaces, styles, and experience. It's like saying you want one vehicle that drives like a motorcycle, haules the kids around, gets great mileage, and can tow 20,000lbs.

All your tools fit in the same toolbox, but you use each one separately for the use it's best suited. Then you put it down and pick up another. Sure you can make a multi-tool but it won't do any job as well as a proper dedicated tool. It'll just kinda work if you have no better option.
