Compilers

There are currently 3 actively developed major D compilers:

DMD » Digital Mars D compiler The reference implementation of D. DMD on GitHub DMD Portal »

GDC » GCC D compiler Fast and open source. GDC on GitHub GDC Portal »

LDC » LLVM D compiler Fast and open source. LDC on GitHub LDC Portal »

Which compiler should I use?

If you're a beginner DMD is the recommended choice, as it is the implementation closest to the D Language Specification. Otherwise it depends on what you need, what platforms you intend to develop for, and your personal preferences.
