This is a simple frontend/backend to grab all the "good first issues" from a number of Github orgs/repos.
Starting from a list of orgs/repos, we use GraphQL to query the Github endpoint for their issues. And then we filter for issues that have the tag "good-first-issues" (and slight variations). We then simply add them up and give people a simple frontend to view the list.
