GAKU Engine, or just "GAKU" for short is the "Genshin Academic Karte Unification Engine". The gaku character 「学」 means "Learning", so saying GAKU Engine is roughly equivilent to saying "Learning Engine".

GAKU is a modular, extendable, Open Source school and student management system built on Rails. GAKU is currently under heavy development.

We do not currently recommend anyone use it in a production environment.


This software is dual licensed under the GNU GPL version 3 and the AGPL version 3. Separate licenses are available upon consultation. Please contact for details.

What does it do?

GAKU Engine is a full school and student management solution including student, staff, syllabus, course, class, exam management and more. It has a full grading system and offers templatable printable reports. Functionality can be enhanced with extensions and can be integrated with external services and clients using the API.

GAKU Engine is also:

  • Completely Open Source, Free as in Freedom, licensed under the GPL v3 and AGPL 3.
  • It only uses Free Open Source components and does not rely on a licensed back end.
  • There are no per-seat licenses.
  • It's Rails based, so it's easily modifyable and extendable.
  • It does not require a special client to use. Any standards compliant web browser will do.
  • It is multi-locale.

Each component of GAKU Engine has its own set of tests. Core functionality is found in core, Front End functionality is forund in frontend, etc. Generally you'll want to run tests in core, so the example here is for core.

Change to core engine:

Recreate test_app:

$ bundle exec rake test_app

Run specs using Selenium:

$ rspec



Development continuing is contigent upon receiving proper funding. We'll be running a Kickstarter to try and raise funds but we are also open to other investments including VC.
