## What it is
Dependabot-Core is the Ruby library powering GitHub's Dependabot automated dependency updates. It resolves and updates dependencies across many ecosystems and generates pull requests with changelogs and release notes.

## Use cases
- automatically update project dependencies via pull requests
- keep lockfiles and manifests up to date
- apply security updates for vulnerable dependencies
- run a self-hosted Dependabot on GitLab or Azure DevOps
- update Docker base images and Terraform modules automatically
- generate PR descriptions with changelogs and release notes

## When to choose
- you want automated dependency update PRs across many languages
- you need to run Dependabot outside GitHub.com on other forges
- you want resolvable version bumps that respect lockfiles

## When to avoid
- you only need vulnerability alerts rather than update PRs
- your package ecosystem is not among the supported ones
- you want a turnkey service rather than a library needing an entrypoint

## Facets
- artifact type: library
- maturity: active
- function: dependency-audit, developer-tools, workflow-automation, ci-cd
- domain: developer-tools, version-control, security
- platform: cloud
- tags: dependency-updates, automated-pull-requests, supply-chain-security, lockfiles, multi-language, github-app, automation, docker, github, gitlab, azure-devops, bitbucket
