The free JME Molecular Editor is a Java applet which allows easy creation and editing of organic molecules and reactions directly within web page, and creation of molecule SMILES or Molfile

Free chemical structure visualization plug-in. [Tutorial]

A molecular graphics program intended for the visualization of proteins, nucleic acids and small molecules. [FAQ]

Introduction to computational modelling methods used nowadays as standard tools by organic chemists for searching for, rationalising and predicting structure and reactivity of organic, bio-organic and organometallic molecules.

This list concentrates on programs for which the source code is available in some form.

WWW software for drawing a molecular structure, running calculations (Gaussian, MOPAC and GAMESS supported) and visualization/manipulation of the results.

Program to convert, manage andvisualize of 3D structures for several platforms (Win32, Linux, Irix, AmigaOs)

On-line tool which allows to draw chemical structures and various drug-relevant properties are calculated on-the-fly. The prediction results are valued and color coded. A green color indicates drug-conform behaviour but properties with high risks of undesired effects (e.g. mutagenicity or poor intestinal absorption) are shown in red.

Free interactive calculation of molecular properties (including logP, polar surface area and other useful descriptors) and calculation of drug-likeness score for GPCR ligands, ion channel modulators and kinase inhibitors.

A moderated discussion list for general and topical aspects of chemical applications of the Internet in general and the World-Wide Web in particular. [Archive]
