GitHubLens — Profile & Repo Analyzer

Live demo: githublens-kappa.vercel.app

Analyze any GitHub profile in one view: total stars and forks, language breakdown, top repositories, account age, and a computed developer score. Powered by the live GitHub REST API through a serverless route.

Features

• Live analysis — enter any username and fetch their profile and repositories in real time.
• Developer score — a 0-100 gauge derived from stars, followers, repo count, language diversity, and account age.
• Language breakdown — a donut chart of the languages across their non-forked repos.
• Top repositories — the most-starred repos with language, stars, forks, and quick links.
• Stat tiles — total stars, forks, repos, followers, following, and languages.
• Graceful handling of rate limits, missing users, and network errors.
