scala-steward

scala-steward (scala-steward-org/scala-steward) is an open-source bot that automatically opens pull requests to update Scala project dependencies. It is the Scala- ecosystem analogue of Dependabot, specifically aware of sbt, Mill, and other Scala build tools and their library catalogues.

The bot runs on a schedule (commonly once/day), detects new versions of direct dependencies in build.sbt / project/plugins.sbt / Mill build files, opens PRs per update, and monitors CI status.

Positioning

Named by Zalando alongside Dependabot as the per-repo tactical layer the fleet-wide SBOM-corpus approach complements:

"Some teams use tools like dependabot, scala-steward that create pull requests in repositories when new library versions are available." (Source: )
