Overall verdict

  • StackStats.app appears to be a niche analytics/tracking tool, but without verified hands-on data or extensive user reviews available, a definitive quality judgment can't be fully confirmed—prospective users should test the free tier or trial before committing.

Why this product is good

  • Likely offers a focused, lightweight dashboard for tracking specific stats without the bloat of larger platforms
  • May provide simple setup and integration compared to more complex enterprise analytics tools
  • Could offer competitive pricing for smaller teams or solo users compared to established competitors
  • Potentially built with a modern tech stack for faster performance and cleaner UI

Recommended for

  • Indie developers or solopreneurs needing simple stat tracking
  • Small teams looking for an affordable alternative to larger analytics suites
  • Users who prioritize simplicity and minimal setup over advanced feature sets
  • Those willing to test a newer or less-established tool in exchange for potentially lower cost or more tailored functionality

Questions & Answers

As answered by people managing HeyGen and StackStats.app.

What's the story behind your product?

StackStats.app's answer:

I built StackStats because Substack's native analytics weren't cutting it. I wanted cohort data, real open rates (not bot-inflated), and a way to identify which posts were actually driving subscriber growth — but every tool I found was either cloud-based or required migrating off Substack entirely. So I built a local app that works with Substack's own CSV exports. No migration, no cloud, no subscription.

What makes your product unique?

StackStats.app's answer:

StackStats runs 100% locally on your machine — your subscriber data never touches a server. It also goes far beyond what Substack shows natively: bot-filtered open rates, cohort retention, superfan identification, dead subscriber detection, and content-to-growth correlation. No subscription, no account, no cloud. Pay once, own it forever.

Why should a person choose your product over its competitors?

StackStats.app's answer:

Most newsletter analytics tools are cloud-based SaaS with monthly subscriptions. StackStats is a one-time purchase that runs entirely on your device. For Substack writers who care about privacy — especially those with paid subscribers — that's a meaningful difference. You also get analytics features that don't exist anywhere else, like bot-filtered open rates and cohort retention, without having to migrate away from Substack.

How would you describe the primary audience of your product?

StackStats.app's answer:

Serious Substack writers who are frustrated by Substack's shallow native analytics and want real data to drive growth — without moving their subscriber data to the cloud.

Which are the primary technologies used for building your product?

StackStats.app's answer:

Electron (macOS + Windows), HTML/CSS/JavaScript, Chart.js, PapaParse. Optional AI layer supports Ollama, Claude, GPT-4, Gemini, Groq, and OpenRouter. Licensing via Cloudflare Workers + D1. Payments via Gumroad.
