Bazel Steward is a bot that helps you keep your library dependencies, Bazel and Bazel rules up-to-date.
Bazel Steward scans your repository looking for outside dependencies. Then, it compares a version of the found dependency against a remote repository. If a newer version is available on the remote repository, then it opens a pull request with a change for that newer version.
The documentation is available at https://virtuslab.github.io/bazel-steward
