opTeX is the current generation of opmac from the same author as opmac. It installs as a format with LuaTeX and should be runnable as optex filename where filename is the name of the file to be processed (and will not need to do \input opmac at the beginning of the file).

The original opmac files which haven’t been updated since 2017 are still available at <> Note that you will also need to install csplain from the TeX Live Manager to get the ams-math dependency.
