Avogadro 2 Avogadro 2

Latest Release BSD License Build Status PRs Welcome GitHub contributors OpenCollective Backers


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.

Core features and goals of the Avogadro project include:

  • Open source distributed under the liberal 3-clause BSD license
  • Cross platform with 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

The code in this repository is a rewrite of Avogadro with source code split across a libraries repository and an application repository. The new code architecture provides a high-performance rendering engine, modern code development, and significantly improved speed and stability.

Avogadro 2 is being developed as part of the Open Chemistry project by an open community, and was started at Kitware as an open source community project. The Avogadro 1.x series currently has more features, and can be found here. We are actively 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 GitHub actions for:
