Renovate vs Dependabot — Automated Dependency Updates in 2026

Outdated dependencies are a security risk and a tech debt problem. Both Renovate and Dependabot automate updates — but they have very different levels of flexibility.

Quick Decision

Dependabot

Built into GitHub. Zero infrastructure needed. Enable with one YAML file.

# .github/dependabot.yml
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    
  - package-ecosystem: "docker"
    directory: "/"
    schedule:
      interval: "weekly"
 
  - package-ecosystem: "github-actions"
    directory: "/"
    schedule:
      interval: "weekly"

What Dependabot does well:

• Zero setup for GitHub repos — just the config file
• Native GitHub integration — security alerts, PR checks, Dependabot alerts
• Supports npm, pip, Maven, Gradle, Go modules, Docker, GitHub Actions, Terraform, and more
• Free for all GitHub repos

Dependabot limitations:

• One PR per dependency update (no grouping natively — though GitHub added basic grouping recently)
• No Helm chart support
• Limited customization — can't set complex rules
• No self-hosted option — GitHub only
• Can't merge PRs automatically based on test results in all cases

Renovate

Open source, runs as a GitHub App or self-hosted. Highly configurable.

// renovate.json
{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "extends": ["config:base"],
  "schedule": ["before 6am on Monday"],
  "packageRules": [
    {
      "matchUpdateTypes": ["minor", "patch"],
      "matchCurrentVersion": "!/^0/",
      "automerge": true       // Auto-merge minor/patch if tests pass
    },
    {
      "groupName": "all non-major dependencies",
      "matchUpdateTypes": ["minor", "patch"],
      "groupSlug": "all-minor-patch"  // One PR for all minor/patch updates
    },
    {
      "matchPackagePatterns": ["^aws-sdk"],
      "groupName": "AWS SDK packages"
    }
  ]
}

What Renovate does better:

• Grouping — one PR for all minor updates instead of 50 separate PRs
• Automerge — auto-merges if tests pass (configurable per package type)
• Helm charts — updates Chart.yaml dependencies
• Docker image digests — pins to SHA digest, not just tag
• Monorepo support — handles complex directory structures
• Platform support — GitHub, GitLab, Bitbucket, Gitea, Azure DevOps
• Custom datasources — can check custom registries

Grouping — The Key Difference

With Dependabot, 20 npm packages with patch updates = 20 PRs. Your PR inbox becomes chaos.

With Renovate:

{
  "packageRules": [
    {
      "matchUpdateTypes": ["patch"],
      "groupName": "all patches",
      "automerge": true    // All patches: one PR, auto-merged if tests pass
    },
    {
      "matchUpdateTypes": ["minor"],
      "groupName": "all minor updates"  // All minors: one PR to review
    }
  ]
}

Result: one PR for all patch updates (auto-merged), one PR for all minor updates (reviewed weekly). Instead of 20 PRs, you get 2.

Docker + Helm Updates

Dependabot handles Dockerfile FROM image updates. It does not handle Helm chart dependencies.

Renovate handles both:

// renovate.json — update Helm chart dependencies
{
  "helm-values": {
    "fileMatch": ["(^|/)values\\.yaml$"]
  },
  "packageRules": [
    {
      "matchDatasources": ["helm"],
      "automerge": false    // Manual review for Helm chart updates
    }
  ]
}

Running Renovate

Option 1: GitHub App (easiest) Install the Mend Renovate GitHub App from the GitHub Marketplace. Free for open source, paid for private repos beyond a limit.

Option 2: Self-hosted

# Run Renovate as a GitHub Actions cron
name: Renovate
on:
  schedule:
    - cron: '0 2 * * 1'   # Every Monday 2 AM
 
jobs:
  renovate:
    runs-on: ubuntu-latest
    steps:
      - uses: renovatebot/github-action@v40
        with:
          token: ${{ secrets.RENOVATE_TOKEN }}

Which to Use

Use Dependabot if:

• Simple repos, small teams
• GitHub-only and zero-config matters
• No Helm charts or complex monorepos

Use Renovate if:

• Monorepo or multiple package managers
• You want grouped PRs and automerge
• Helm chart or Docker digest updates needed
• GitLab, Bitbucket, or self-hosted Git

Many teams use both: Dependabot for security alerts (it integrates with GitHub's security advisory database), Renovate for actual update PRs.
