Avogadro 2

Avogadro 2


Avogadro 2 is a rewrite of Avogadro, and still lacks features present in Avogadro 1. Both packages can be installed on the same system, and so it is possible to try the latest without losing access to the previous version. We will be making occasional releases of Avogadro 1.x too, along with migrating functionality to Avogadro 2. We value your feedback, and hope that you will find the improvements made in version 2 useful.

Avogadro is an advanced molecular editor designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science, and related areas. It offers flexible rendering and a powerful plugin architecture. The code in this repository is a rewrite of Avogadro with source code split across a libraries repository and an application repository. Core features and goals of the Avogadro project:

  • Open source distributed under the liberal 3-clause BSD license
  • Cross platform with nightly builds on Linux, Mac OS X and Windows
  • Intuitive interface designed to be useful to whole community
  • Fast and efficient embracing the latest technologies
  • Extensible, making extensive use of a plugin architecture
  • Flexible supporting a range of chemical data formats and packages

Open Chemistry project Kitware, Inc.

Avogadro 2 is being developed as part of the Open Chemistry project at Kitware, along with companion tools and libraries to support the work. The Avogadro 1.x series currently has more features, and can be found here. We will be porting more features to the Avogadro 2 code base, and making regular releases to get feedback from the community.


We provide nightly binaries built by our dashboards for Mac OS X and Windows. If you would like to build from source we recommend that you follow our building Open Chemistry guide that will take care of building most dependencies.


Our project uses Gerrit for code review, and CDash@Home to test proposed patches before they are merged. Please check our development guide for more details on developing and contributing to the project. The project pages provide bug, feature and support trackers, along with many other features such as source browsing.

Our wiki is used to document features, flesh out designs and host other documentation. Our API is documented using Doxygen with updated documentation generated nightly. We have several mailing lists to coordinate development and to provide support.
