Phonopy is an open source package for phonon calculations at harmonic and quasi-harmonic levels.

Phono3py is another open source package for phonon-phonon interaction and lattice thermal conductivity calculations. See the documentation at http://phonopy.github.io/phono3py/

Phonon database: A collection of first principles phonon calculations is available as open data at http://phonondb.mtl.kyoto-u.ac.jp/ , where the raw data of phonopy & VASP results are downloaded.

The following features of phonopy are highlighted:
