history
Project history and usage
cargo-deny is an Embark Studios Cargo plugin for linting Rust dependency graphs. It checks advisories, license policy, banned crates, duplicate versions, and allowed package sources from a project-level deny.toml file.
Project history
Embark Studios created the repository and published the crate in May 2019. The README frames cargo-deny as an open-source release of a tool Embark uses internally, with a dedicated book for in-depth documentation.
The project grew into one of the standard Rust dependency-policy tools, with docs organized around checks for licenses, bans, advisories, and sources. Its repository topics and README both present it as a Cargo subcommand for dependency linting.
Adoption history
cargo-deny has broad adoption for Rust CI because it covers policy decisions that Cargo itself intentionally does not enforce: which licenses are acceptable, whether multiple versions are allowed, whether vulnerable advisories should fail builds, and which registries or git sources are trusted.
The tool is packaged in apk, Homebrew, dnf, Nix, and pacman, and crates.io metadata shows more than four million downloads by June 2026. The README also points to cargo-deny-action for GitHub Actions use.
How it is used
The quickstart is `cargo install --locked cargo-deny && cargo deny init && cargo deny check`. The init command creates a deny.toml template in the current working directory unless a path is supplied.
Users commonly run `cargo deny check` in CI, or run targeted checks such as `cargo deny check licenses`, `cargo deny check bans`, `cargo deny check advisories`, and `cargo deny check sources`.
Why package nerds care
cargo-deny is package-nerd infrastructure because it makes dependency policy executable. Instead of tracking license allowlists, source restrictions, duplicate-version rules, and advisories in prose, teams can encode them in deny.toml and fail builds consistently.
It is also an example of Cargo's external-tool model handling ecosystem governance concerns without bloating Cargo itself.
