Ship with confidence. semrel reads your commits, calculates the next version, and publishes the release — automatically.
Why semrel?
Section titled “Why semrel?”Fully pluggable
Every step of the pipeline is a swappable subprocess plugin. Swap the GitHub provider for GitLab, replace the changelog generator, or add a Slack notification — without touching core semrel.
Monorepo ready
Version multiple independent modules in a single repository, each with its own tag series and config file.
Supply chain security
Signed releases with Sigstore Cosign, CycloneDX/SPDX SBOM, SLSA Level 1 provenance. DCO sign-off and REUSE/SPDX compliance enforced on every PR.
Language agnostic plugins
Plugins are plain subprocess binaries — write them in Go, Python, Rust, Node.js, or any language you like.
Dry-run mode
Preview exactly what semrel would do before touching anything. Run semrel release --dry-run in CI to validate your config safely.
