⭐ Introducing starhistory.io — Professional Star History Charts

We built starhistory.io — a professional GitHub star history chart service powered by gogpu/gg.

Why?

On June 30, 2026, GitHub restricted the Stargazers API. star-history.com and every other star history tool stopped working (GitHub is reportedly working on a resolution, but no timeline has been announced). Our own README embeds broke.

starhistory.io solves this with a GitHub App — install once, auto-renewing tokens, works forever.

Features

• 🎨 5 chart styles — professional, dark, minimal, comparison, dark-comparison
• 📊 Multi-repo comparison — colorblind-safe Okabe-Ito palette
• 📅 Time ranges — ?range=90d, ?range=1y, custom from/to dates
• ⚡ Incremental fetch — repeat visits use 1 API call instead of hundreds
• 🔄 Unstar detection — tracks full star/unstar lifecycle
• 🖼️ Error images with QR code — when App not installed, shows instructions
• 🔒 Security — IP-restricted tokens, non-root Docker, auto-expiring tokens

How to use

1. Install the starhistory-io GitHub App on your org/account
2. Add to your README:

<a href="https://starhistory.io">
 <picture>
   <source media="(prefers-color-scheme: dark)" srcset="https://api.starhistory.io/png?repos=YOUR_ORG/YOUR_REPO&style=dark" />
   <source media="(prefers-color-scheme: light)" srcset="https://api.starhistory.io/png?repos=YOUR_ORG/YOUR_REPO&style=professional" />
   <img src="https://api.starhistory.io/png?repos=YOUR_ORG/YOUR_REPO" width="800" alt="Star History" />
 </picture>
</a>

Live examples

• gogpu/gogpu README — single repo chart
• GoGPU org profile — 5-repo ecosystem comparison
• born-ml/born README — cross-org support
• golang/go — what it looks like when App is not installed (error image with QR code and install instructions)

About the "write" permission

GitHub requires contents: write to access the Stargazers API — there is no stargazers: read permission. We only read star data — never write to your repositories. IP-restricted tokens, open source code (coming soon). Details

What's next

We're working on a personal dashboard (app.starhistory.io) with extended features — chart customization, star/unstar analytics, daily tracking for repos without App access, and more. It's not ready yet — right now it's a bare API service + landing page.

The code will be open-sourced once we bring it to our enterprise quality standards. There's still a lot of work — SVG export, GitHub Action, Angular frontend, daily cron, and more.

Built with GoGPU

starhistory.io is a real-world production service powered by gogpu/gg — our 2D graphics engine. Every chart is rendered server-side with Skia-quality anti-aliasing, LTTB downsampling, and 2x Retina output. The ultimate dogfooding showcase for the ecosystem.
