> Hex-Rays did ultimately release IDA Home, but you have to sign up for an account to even find out what their hobbyist license costs.
And even then, IDA Home comes with some pretty serious limitations. It's not just a no-commercial-use version of IDA Pro; it's also a cut-down version with no decompiler, no batch mode, and which only disassembles code for one processor family (which you have to choose at the time of purchase, from a limited subset of what IDA Pro supports).
IDA Pro doesn't come with a decompiler either. For that you need to spend extra and pay for the hex-rays license on top of the price for the disassembler.
The total price kicks licensing costs well outside that of hobbyist use cases.
For IDA Home they do give you their cloud decompiler for 64-bit binaries: “The 64-bit PC, ARM and PPC come with a compatible cloud-based Decompiler currently in beta testing mode”
