Welcome to the Tsugi project. Our goal is to build a scalable multi-tenant "tool" hosting environment based on the emerging IMS standards to help move the industry toward a Next Generation Digital Learning Environment (NGDLE).

You can play with the Tsugi developer console on this site:
Please do not use the testing key/secret for anything that is production. The data associated with the key "12345" is regularly cleared off this system without any notification.
If you want to use Tsugi tools in your courses, see sites like www.wa4e.com or www.py4e.com. Log into the site, and select "LMS Integration" to apply for a key that you can safely use in your classes.
You can join the Tsugi developer's list at
If you have a production instance of Tsugi and would like to be listed here, please contact me or send a Pull Request for this page via GitHub. If you provide me with a mailing address, I will send you a Tsugi Swiss Army Knife (while supplies last).
Tsugi is a framework that handles much of the low-level detail of building multi-tenant tool that makes use of the IMS Learning Tools Interoperability™ (LTI)™ and other learning tool interoperability standards. The Tsugi Framework provides library and database code to receive and model all of the incoming LTI data in database tables and sets up a session with the important information about the LMS, user, and course.
If you are interested in Supporting the Tsugi Effort, please let us know.
Learning Tools Interoperability™ (LTI™) is a trademark of IMS Global Learning Consortium, Inc. in the United States and/or other countries.
This is an open source effort that is still in active development and evolution. We can use lots of help and financial support. Here are some ways to support Tsugi.
Join the Apereo Foundation. Tsugi is an incubating project within Apereo and any support you give to Apereo by joining, participating, and/or coming to Apereo meetings helps the cause of all Apereo projects.
Contribute funds to the Apereo Foundation tagged for the Tsugi project. This give us funds to spend on things like students, support travel to meetings, graphic design, etc.
If you want to fund Dr. Chuck's research efforts (like a grant) on Tsugi at the University of Michigan School of Information please contact him.
If you are a granting or philanthropic organization interested in improving educational technology and think that Tsugi might be a good addition to your project portfolio, please contact Chuck to get a proposal developed.
If you have an educational technology grant and would like to use Tsugi and provide some funds to our project to help make your project a success, it would be much appreciated. Again, contact Chuck.
If none of the above make sense to you, just hit the "donate" button below and I will make sure the funds are applied as best appropriate.
