You still can, for free and all. Sure, Borland -- and the whole litany of company names that have owned Delphi, the product, since -- have on-and-off had "free" (=as in beer) editions, but that on-and-off inconsistency tends to sour my perspective on those. But, the venerable Free Pascal language and compiler gained (after a few fits and starts) a sister project, Lazarus[1], which is basically a clone of the Delphi class library and graphical IDE.
All FOSS all the way down. To quote jerryp, "Recommended."
