Dependabot
Dependency update PR bot
FreeCode review, testing & securitydocs.github.com
What it is
GitHub-native bot with three jobs: alerts for vulnerable dependencies drawn from the GitHub Advisory Database, security updates that automatically open pull requests bumping to a patched version, and scheduled version updates configured in
.github/dependabot.yml. Grouped updates and auto-merge rules keep pull request volume manageable.Why it earns a slot
Zero-cost, near-zero-config baseline. The
package.json your agent wrote will drift into known-CVE territory within months, and this is the one tool that quietly fixes it while you sleep.Know before you commit
It only knows advisories already published to GitHub's database, so brand-new malicious packages slip through; pair it with Socket. It also skips archived repos, and ungrouped updates get spammy fast.
Getting started
Enable under repo Settings > Code security, then add .github/dependabot.yml
