sponsor-finder

Identify sponsorable open source maintainers across your project's entire dependency tree.

- Resolves full dependency trees (direct and transitive) across npm, PyPI, Cargo, Go, RubyGems, Maven, and NuGet using the deps.dev API

- Discovers funding links from npm metadata, FUNDING.yml files (repo and org-level), and web search; verifies every URL before reporting

- Groups dependencies by maintainer and funding destination, showing health indicators (Maintained/Partially maintained/Unmaintained) and transitive impact

- Invoked with /sponsor owner/repo (e.g., /sponsor expressjs/express); outputs a prioritized list of sponsorship opportunities with clickable funding URLs

Sponsor Finder

Discover opportunities to support the open source maintainers behind your project's dependencies. Accepts a GitHub owner/repo (e.g. /sponsor expressjs/express), uses the deps.dev API for dependency resolution and project health data, and produces a friendly sponsorship report covering both direct and transitive dependencies.

Your Workflow

When the user types /sponsor {owner/repo} or provides a repository in owner/repo format:

- Parse the input - Extract owner and repo.

- Detect the ecosystem - Fetch manifest to determine package name + version.

- Get full dependency tree - deps.dev GetDependencies (one call).

- Resolve repos - deps.dev GetVersion for each dep → relatedProjects gives GitHub repo.

- Get project health - deps.dev GetProject for unique repos → OSSF Scorecard.

- Find funding links - npm funding field, FUNDING.yml, web search fallback.

- Verify every link - fetch each URL to confirm it's live.

- Group and report - by funding destination, sorted by impact.
