FAQ

Questions, answered.

What package ecosystems does Dependabot support?＋

Dependabot supports npm, pip, Maven, Gradle, NuGet, Go modules, Cargo, Bundler, Composer and many others. GitHub maintains a full list of supported ecosystems in their documentation.

Does Dependabot automatically merge pull requests?＋

No, Dependabot creates pull requests but does not auto-merge them. You can enable GitHub auto-merge on the PR, but Dependabot itself only opens, updates and optionally rebases the PRs.

Yes, Dependabot can be configured to only create pull requests for security updates. You can also limit updates to specific ecosystems, set a maximum number of open PRs and schedule updates to run weekly instead of daily.
