I have been working on this alone for 6 years.

cmusee is not a step debugger like GDB.

It records every function call and assignment statement, and then present it entirety

This is the minimum memory required to record some projects.

curl 6MB

flatbuffers 6MB

git 14MB

jq 26MB

nlohmann/json 18MB

raylib 199MB

llvm llc 649MB

llvm opt 182MB
