Avogadro 2

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][Avogadro1], which is now unsupported. The successor is faster, better, much more stable, and [more feature-rich] (https://two.avogadro.cc/docs/whats-new-in-avogadro-2/).

Avogadro's codebase is split across a and an application repository (opens in a new tab). 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][OpenChemistry] project by an open community, which was started at [Kitware][Kitware] as an open-source community project.
