What Hacker News says?
It's not the first real competitor available to the public. Hopper Disassembler and Binary Ninja are both capable. They have been available for a few years. Binary Ninja is also collaborative if you get the enterprise edition: https://binary.ninja/purchase/

HN discussionCutter is "A Qt and C++ GUI for radare2". There are more alternatives to IDA Pro. Hopper Disassembler is one. Binary Ninja (binja) is another.

They do great work. They really understand security and t…

HN discussionThe graph is generated by binary ninja [1] fully automatically, and this is just a screenshot of the tool. Any alternative reversing platform or disassembly tool like IDA Pro can generate you something very similar. [1] https://binary.ninja/
