GCD Web Application

This file last updated: Aug 2020

This is the current implementation of the Grand Comics Database, hosted at (production) and (public beta for new features).

See the Technical section on and the Wiki for more detailed information about how we work and what has been done to date. This file just covers the essentials of branches and code reviews.

Please join the gcd-tech list for help and to find out where we could use your contributions:

Setting up a Development Environment

Our Vagrant-setup needs updating ! We used recommend that you use our Vagrant-based development environment, but it is not working any more and currently no one with expertise to update it.

You can find manual instructions for various platforms in the docs directory GCD Docs but they aren't necessarily up to date. As of Aug 2019 they should work.


Our primary collaboration space is the gcd-tech mailing list. We use the GitHub code review system for discussing code changes.

Pull requests are welcome, but you might want to poke the mailing list if no one seems to be paying attention.



This is (generally) the production deployment. For the most part, work should not be done here directly.

This is the general-purpose development branch. It is often deployed to the beta site, and most work should be done here. Special-purpose development branches are based from beta unless otherwise noted.

This branch is for experimental work to refactor the system in several stages.

There will probably be some modernization and code clean-up along the way.

Contact: handrews via gcd-tech


This is an experimental branch for developing the REST API. We expect that proceeding here will also involve some code clean-up to move the web UI onto the REST API. It is not yet determined how often this branch will merge to beta.

History of the Code

The current production code runs on Django 2.2.

This version of the GCD web application was initially written in Python using Django 0.96, and rushed into deployment in late 2009 when the prior system's host crashed after many years of service. Due to both of these facts, there remain some oddities and things that you would not see in a modern Django system.

Reporting or Examining Bugs

Bugs and feature requests are currently recorded in GitHub's issue tracking system. We previously used an instance of Bugzilla but all bugs/requests from that system have been moved to GitHub.

If you are unfamiliar with the code, please contact the gcd-tech list before starting to submit fixes.


In addition to the contributors you see within the git log, we'd like to thank Jon Løvstadt for his work developing and running the previous iteration of the GCD web application.

You can’t perform that action at this time.
