Avogadro 2

Introduction

Avogadro is an advanced molecular editor designed for cross-platform use in computational chemistry, molecular modeling, education, 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
• An intuitive interface designed to be useful to the 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

Avogadro 2 began as a rewrite of the original Avogadro 1.x, which is now unsupported. The successor is faster, better, much more stable, and more featureful. A final couple of features yet to be ported will be implemented by the time of the 2.0 release, but in the meantime Avogadro 2 already has much new functionality of its own.

Avogadro's codebase is 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 is being developed as part of the Open Chemistry project by an open community, which was started at Kitware as an open-source community project.
