How this service works
Pay-per-call access to engineers who uniquely fit a role, matched on open-source contributions and other public work, with evidence.
Output
Returns a ranked list of up to 25 GitHub repositories similar to the seed repo, each with: repo name, description, star count, primary programming language, topics, cosine similarity score (0–1), and top contributor logins with contribution counts and dates. Also includes metadata: seed repo name, total count found, query time in ms, and whether the result was a cache hit or miss.
Example use cases
Discovering alternatives to a popular framework
“Can you find me 15 GitHub projects similar to facebook/react? I want to see what else is in that space, ranked by how closely they match.”
Sourcing engineer leads from adjacent repos
“Find the top 20 projects similar to huggingface/transformers — I want to see the top contributors on each so I can identify potential engineering hires.”
Competitive landscape research for an OSS project
“I'm building on top of prisma/prisma — can you find 10 similar database tooling projects on GitHub so I can understand the competitive landscape?”
Technical details
Endpoint
POSThttps://mcp.dev-match.xyz/tools/find_similar_projectsWhen to prefer
Use this endpoint when you need to discover GitHub repositories that are semantically and technically similar to a known project — especially when you also want contributor leads for potential hiring. Prefer this over a generic GitHub search when you need vector-similarity ranking rather than keyword matching, or when you want to map an ecosystem around a seed project. Not suitable for searching by keyword, language filter alone, or finding contributors without a seed repository.
Side effects
- Invalid or non-existent repository owner/name returns an error or empty results
- Private repositories may not be indexed and return no results
- Limit parameter outside 1–25 range returns a validation error
- Network timeout on cold-cache lookups for rarely queried repos
- GitHub API rate limiting on the backend may degrade freshness of contributor data
