SymPy has made a start on an open source version of Alpha, SymPy Gamma,

The biggest missing piece it's missing is the data used by Alpha. It's missing other things as well, but it's a start.

I don't know if it's too late for this, but as a matter of marketing, why not Omega instead of Gamma? Alpha was the first word on the subject. Omega will be the last.

I wasn't involved in the Gamma aspects of SymPy. At this point, Gamma is probably more appropriate.
