Create a .github/dependabot.yml file from a compact JSON definition. Each update block is checked for a supported package ecosystem, absolute directory, schedule interval, and practical pull-request limits before valid YAML is emitted.

What this developer tool does

The generator maps camelCase JSON options to Dependabot keys and emits one update block for each ecosystem and directory pair.

The generator maps camelCase JSON options to Dependabot keys and emits one update block for each ecosystem and directory pair.

Commit the result as .github/dependabot.yml on the default branch. Dependabot reads configuration only from that location.

Example

Try the sample input built into the page. The result uses the same validation and export path as pasted content.

{"updates":[{"ecosystem":"npm","directory":"/","interval":"weekly","openPullRequestsLimit":5},{"ecosystem":"github-actions","directory":"/","interval":"monthly"}]}

Use cases

  • Prepare repository configuration during project setup.
  • Review a proposed change before opening a pull request.
  • Turn issue or workflow data into a consistent, copy-ready artifact.

Tips for reliable output

  • Start with the sample to confirm the expected shape.
  • Keep repository names, paths, and owner handles exact.
  • Read warnings even when output is generated.
  • Commit configuration changes in a separate pull request when practical.
  • Test critical automation on a non-production branch first.

Processing details

Supported fields include ecosystem, directory, interval, day, time, timezone, targetBranch, openPullRequestsLimit, labels, reviewers, and assignees.

Repository-specific registries and advanced groups are not generated. Add them manually when private dependencies or grouped updates are required.

Frequently asked questions

What input does the Dependabot Config Generator accept?

Use the format shown in the sample. The page validates required fields and reports malformed lines or values before producing output.

Does the Dependabot Config Generator contact GitHub or another server?

No. Processing happens in your browser and the core function makes no network request.

Can I use the generated output in a repository?

Yes, after reviewing repository-specific names, permissions, paths, and policies that a browser-only tool cannot verify.

Why might GitHub interpret the result differently?

Hosted services may apply repository context, current platform rules, presets, or permissions that are unavailable to this local check.

Can the Dependabot Config Generator process Unicode text?

Yes. The input and downloaded files use UTF-8, although the target format may impose narrower naming or syntax rules.
