Calagator is an open source calendar aggregator developed by the Portland Tech Community.

The Toledo region tech community uses a version of it for its own community calendar, hosted at tol-calagator.org. Jason Slagle set it up for the community.

In 2013, the domain name was changed to toledotechevents.org to make it easier to remember.
