  1. Zero config, just prepend your command with red
  2. Time traveling (can step back in time)
  3. Printing arbitrary values and structs
  4. Adding and removing breakpoints
  5. More to come. See TODO file


  1. Make sure your build target is byte-code, not native:

     ocamlbuild myapp.d.byte
  2. Clone the repo and run RED:

     git clone
     ./red/ /path/to/myapp.d.byte
