A Django app that acts as a wrapper around the package value-of-information (tadamcz/value-of-information). That package is included as a git submodule, and listed in pyproject.toml as a local dependency in editable mode.
Queries take from a few seconds to many minutes to execute. Therefore, they are sent to a task queue (based on Django-Q). Once a query completes, the results are displayed in the browser.
The initial skeleton was set up using Cookiecutter Django. See README_cookiecutter.md.
The best entrypoint into the code is probably views.py.
Deployed using Dokku, an open source and customisable alternative to PaaS such as Heroku. It's currently deployed on an AWS EC2 instance. The files used by Dokku are .buildpacks, .env, and app.json.

Open Philanthropy plans to use this tool as one input into the decision of whether to fund randomized trials in global health or development. Because the concept is quite general, we hope that the tool can also be useful to others.
