Its README presents strict comparison as the baseline and semantic comparison as the more useful mode for image reproducibility checks. ### Adoption history The official README documents binary releases for Linux and macOS, installation through mise, and source installation with Go, which places diffoci in the familiar package-manager and single-binary CLI lane for container tooling. ### How it is used Typical use compares two image references with `diffoci diff IMAGE0 IMAGE1`; the README recommends `--semantic` when timestamp, layer ordering, build history, or image-name annotation noise would make strict output too noisy. It can also compare local Docker or Podman images with `docker://` and `podman://` prefixes and can dump differing files to a report directory. ### Why package nerds care For package maintainers and reproducible-builds people, diffoci fills the gap between byte-level archive comparison and the layered, metadata-heavy world of OCI images. It is useful when the artifact being packaged is not a tarball or binary but a container image with registry, platform, and layer semantics. ### Timeline - 2023: README examples focus on comparing Alpine and Docker Hub images in reproducibility investigations. - 2020s: Project distributed as a Go CLI with Linux and macOS binary releases. ### Related projects - diffoci is adjacent to diffoscope for deep artifact comparison, but specializes in Docker and OCI image layout, containerd, Docker, Podman, and registry workflows. ### Sources - - ## Security Notes broad file, network, media, or database tool signal. infrastructure mutation or orchestration signal. - **Geiger risk:** orange / medium - broad file, network, media, or database tool signal - infrastructure mutation or orchestration signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** diffoci - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - diffoci: normalized package name match | nixpkgs package indexes: pkgs/by-name/di/diffoci/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - pacman - diffoci - 0.1.8-1: normalized package name match | Arch Linux sync databases: diffoci from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | diff for Docker and OCI container images | https://github.com/reproducible-containers/diffoci ## Related links - [Cloud CLI packages](https://www.automicvault.com/pkg/cloud-clis/) - Belongs to a cloud or infrastructure command family. - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [go](https://www.automicvault.com/pkg/brew/go/) - Build dependency declared by Homebrew. - [diffoscope](https://www.automicvault.com/pkg/brew/diffoscope/) - Shares av.db curated category or tags: cli, developer-tools, diff, reproducible-builds. - [oxker](https://www.automicvault.com/pkg/brew/oxker/) - Shares av.db curated category or tags: cli, container-tools, containers, developer-tools, docker. - [colordiff](https://www.automicvault.com/pkg/brew/colordiff/) - Shares av.db curated category or tags: cli, developer-tools, diff. - [diff-so-fancy](https://www.automicvault.com/pkg/brew/diff-so-fancy/) - Shares av.db curated category or tags: cli, developer-tools, diff. - [diffnav](https://www.automicvault.com/pkg/brew/diffnav/) - Shares av.db curated category or tags: cli, developer-tools, diff. - [diffr](https://www.automicvault.com/pkg/brew/diffr/) - Shares av.db curated category or tags: cli, developer-tools, diff. - [diffstat](https://www.automicvault.com/pkg/brew/diffstat/) - Shares av.db curated category or tags: cli, developer-tools, diff. - [difftastic](https://www.automicvault.com/pkg/brew/difftastic/) - Shares av.db curated category or tags: cli, developer-tools, diff. - [manifest-tool](https://www.automicvault.com/pkg/brew/manifest-tool/) - Local package facts share a topical domain.
