An Inorganic Crystal Structures Generator
Jana2006 is a crystallographic program focused to solution, refinement and interpretation of difficult, especially modulated structures.
PLATON is a versatile SHELX97 compatible multipurpose crystallographic tool.
SHELX is a set of programs for crystal structure determination from single-crystal diffraction data.
Oak Ridge Thermal Ellipsoid Plot Program
for Crystal Structure Illustrations.
X-UTIL (pronounce: "subtle") is a set of utility programs intended for (but not limited to) practicing protein crystallographers.
Crunch is a system of Fortran programs and Unix shell-scripts. The aim is the automatic solution of the phase problem in single crystal X-ray diffraction. Given the measured intensities and the usual data such as contents and dimensions of the unitcell, in general Crunch will successfully determine your crystal structure for you.
Software for calculation of diffraction patterns for atomistic models.
A computer program system for crystal structure determination by Patterson methods and direct methods applied to difference structure factors.
Eden is crystallographic real-space electron-density refinement and optimization program that produces electron density maps with minimal model bias in a robust manner.
Reverse Monte Carlo and pseudo simulated annealing code for ab initio crystal structure determination, either from scratch (random starting model) or by "molecule location", fitting either to "|Fobs|" extracted by powder diffractometry or to single crystal data.
Fox, 'Free Objects for Crystallography' is a free, open-source program for the ab initio structure determination from powder diffraction.
The Gnu Xtal System is a reasonably comprehensive, modular suite of software oriented primarily towards small molecule crystallography
Monte Carlo and grid search powder pattern indexing program
RAVE is a suite of programs for single and multiple domain, single and multiple crystal real-space electron-density averaging.
Simultaneous Rietveld Refinement with Multiple Powder Data Sets.
Software for Crystallography
Situs is an award-winning program package for the modeling of atomic resolution structures into low-resolution density maps e.g. from electron microscopy, tomography, or small angle X-ray scattering.
SnB is a computer program based on Shake-and-Bake, a dual-space direct-methods procedure for determining crystal structures from X-ray diffraction data.
XPMA is a mouse driven menu based graphical program for the manipulation of crystal structures.

CRANK (Crunch 2) is a new suite of programs for automated macromolecular structure solution. It uses an XML based framework to join many different crystallography programs into a unified whole.
CCP4 exists to produce and support a world-leading, integrated suite of programs that allows researchers to determine macromolecular structures by X-ray crystallography, and other biophysical techniques.
