Give RepoFinder a GitHub repo or a public website plus a goal (“production evals”, “auth”, “background jobs”) and it returns three to five repos that genuinely complement your project - each with a What, a project-specific Why, a How to integrate, ease and impact ratings, and live GitHub evidence (stars, contributors, commits in the last 90 days). Then an “Ask OpenAI about this repo” chat lets you interrogate any pick: why it ranked, what the tradeoffs are, what else to consider. The point is the tagline: build better, focused, and faster - where your taste matters more than the number of stars.
It grew out of RepoRadar and Repo Recommender, and it is the lighter, sharper take: one engine serving two surfaces, a browser and a remote MCP tool at repofinder.io/mcp that any agent can call. The full build story - the model routing, the anti-hallucination guard, the checked-in lesson course on Codex - is in the write-up.
