Straight from GitHub

Nobody has written up this repo. Everything on this page comes straight from the GitHub API, so there is no founder write-up, no pros and cons, and no difficulty rating — rather than a generated guess at them.

Maintenance

Licence

AGPL-3.0

Tech stack

Primary language: C. GitHub reports only the dominant language, so this is not the whole stack.
