Is there a free implementation of Ada?

Question

I looked at the AdaCore site, as well as for A# (which now appears to be owned by AdaCore) and neither appear to be free (although I could have misread something). Any recommendations?

Answer 1

GNAT is available for download here: https://libre.adacore.com/

Look for "GNAT GPL Edition". Not sure why it is so well hidden on that little known site.

Answer 2

Here's a big list of Ada compilers from Open Directory.

The GNU Ada compiler seems to be a more popular one.
