OneGov Cloud is a RAD framework built with Morepath, the web micro-framework with superpowers. It enables us to write web applications for government agencies in a secure, efficient and modern manner.

OneGov Cloud has strong opinions about the technology it employs. This has the following consequences:

  • It only runs on POSIX platforms.
  • It uses PostgreSQL 9.3+ and won’t support other databases.
  • It requires Python 3.4+. Python 2.x is not supported.
  • It aims to provide concurrency through multiple processes and is not necessarily thread-safe.


OneGov Cloud supports multiple languages and locales. That means that number- date- and other formatting can be done in the appropriate locale. All static text can be easily translated.

Dynamic text (content) can be translated, though OneGov Cloud doesn’t offer any tools for it at this moment. This is generally a UI problem, not a framework problem.

URL paths cannot currently be translated.

Development and documentation is written exclusively in English. It’s what we are most comfortable with when it comes to software development.
