Git-bug: Distributed, offline-first bug tracker embedded in Git

git-bug is a distributed, offline-first bug tracker embedded directly within Git. It eliminates the need for external servers or databases, as issues are stored in the repository and synchronized via git push. By utilizing Git as a content-addressable database, the tool stores arbitrary data in custom refs. This technical approach demonstrates that Git's replication mechanisms can be used for metadata, CI logs, and review notes, extending its utility beyond standard version control functions.
