I Built a Free GitHub Analyzer That Brings Me Paying Clients

I Built a Free GitHub Analyzer (and How It Earns Me Money)

Last week I was screening GitHub repos for a client project and realized something: every developer does this manually. Star count. Last commit date. Tech stack. License.

So I built a tool that does it in one click.

How It Works

Paste any GitHub repo URL and get:

  • Stars, forks, watchers, open issues
  • Tech stack breakdown with percentages
  • Activity health score (very active / low / inactive)
  • Maturity assessment
  • Smart insights like star-to-fork ratio and issue ratio

All in a clean, fast, zero-signup interface. 100% client-side, calls the GitHub API directly.

Why I Built It

I run an AI writing service for developers. Part of my job is understanding what tools my clients use. This analyzer helps me quickly evaluate any repo's health before I write about it.

But here's the interesting part: the tool itself brings me clients.

When a developer uses the analyzer and sees the Get Professional Review CTA, they realize they could pay someone to do a proper architecture review or migration plan. That's where my AI writing/consulting service comes in.

The Bigger Lesson

Build free tools that solve a real pain point. Make the tool genuinely useful on its own. Add a natural CTA for the paid version.

The GitHub Analyzer will work perfectly fine forever as a free tool. But for those who need deeper analysis, I'm here.

What I offer: AI-powered technical writing, code documentation, architecture reviews, and migration plans. See my services.
