Quicken for Linux

We here who are fellow Quicken users and a few Quicken moderators have no idea of the future product roadmap, and those in the know in Quicken management almost never discuss future plans for the products.

That said, I'd think this seems pretty unlikely, for a few reasons. First, if you look at the Mac product, which they've been rebuilding from scratch is now in about its 7th year of development, not counting a few years of work on predecessor products -- and it's still missing quite a few features and functionality compared to the legacy Windows version. It will still take years, even with the expanded Mac development team, to build out the features users are clamoring for. No disrespect to Linux users, but it's a smaller market for Quicken, so it would probably justify a smaller development team, and likely a longer development period. That just seems unlikely.

What about porting chunks of either the existing Windows or Mac code over to run on Linux? Even if that were possible, it misses the fact that both the Windows and Mac products rely deeply on technologies in this operating systems. Quicken Windows requires Microsoft's .Net framework, without which it would require thousands of additional hours of coding. Quicken Mac is built around the Mac's sqlite database, which I imagine might be an easy transition over to Linux, but it also relies heavily on many features in Apple's operating system to do much of the heavy lifting, including Core Data, Core Graphics, the Quartz display system and others. Programming the features Quicken needs from scratch without those tools would probably add years of development work. And even though the Mac operating system is Unix, the Darwin OS that macOS is based on has a different application binary interface from Linux, and the two process system calls differently, so there's no easy path to porting Mac programs to Linux. (There's been a long-running effort to build an emulation layer to run Mac apps on Linux, but I don't think it's ever gotten far enough along to be practical.)

So your best route is likely to be with Quicken Windows via Wine or Crossover emulation or one of several virtual machines. The odds of a native Linux app seem very long to me.

There's a long-running thread about Quicken on Linux you can skim through if you wish:
