- The mission of the Apertium project is to collaboratively develop free/open-source machine translation for as many languages as possible, and in particular:
- To give everyone free, unlimited access to the best possible machine-translation technologies.
- To maintain a modular, documented, open platform for machine translation and other human language processing tasks
- To favour the interchange and reuse of existing linguistic data.
- To make integration with other free/open-source technologies easier.
- To radically guarantee the reproducibility of machine translation and natural language processing research
 Roles and responsibilities
- The most important participants in the project are people who use Apertium. The majority of our developers start out as users and guide their development efforts from the user's perspective

- Developers are volunteers who are contributing time, code, documentation, or resources to Apertium. A developer that makes sustained, welcomed contributions to the project may be invited to become a committer, though the exact timing of such invitations depends on many factors
