Star History — GitHub Repository Growth Tracking for Developer Teams and Open Source Maintainers

Stop flying blind on your open source project's momentum — see exactly how your GitHub stars are growing over time so you can measure community traction and identify what's actually working.

What It Does for Your Business

Star History is a free visualization tool that tracks and displays how GitHub repositories gain stars over time. Instead of just seeing your total star count today, you get a clean graph showing your growth trajectory — week by week, month by month, year by year. For small businesses building open source projects, developer tools, or community-driven products, this means you can finally answer the question: "Is our project actually growing?"

The tool works by pulling public GitHub data and creating an interactive chart. You simply paste your repository URL, and Star History generates a shareable graph showing growth patterns. This is invaluable when pitching to investors, reporting to stakeholders, or simply understanding whether your marketing efforts and product updates are actually driving adoption among developers.

Key Features

• Real-time Growth Charts — See your star history from day one, updated automatically so you always know current momentum
• Multi-Repo Comparison — Track 5+ repositories on one chart to benchmark your project against competitors or your own other projects
• Shareable Graphs — Generate embed-ready SVG images perfect for README files, pitch decks, and investor presentations
• Growth Spike Detection — Instantly spot which launches, features, or announcements actually moved the needle
• Historical Data Export — Download your star history data to analyze growth rates and predict future trends in spreadsheets
• Multiple Chart Types — Switch between line graphs and bar charts depending on what story your data needs to tell

Best For

Software development agencies tracking open source tools, SaaS companies building developer-first products, indie developers measuring community traction, startup founders preparing pitch materials, technical teams benchmarking against competitors, and maintainers of popular GitHub projects who need proof of adoption.

Pricing

100% free. No login required, no hidden paywalls, no premium tier. Star History is completely free to use.

Business ROI

Star History saves small development teams 2-3 hours per week of manual tracking and manual graph creation in spreadsheets. For startup founders, it eliminates the need to pay designers or developers $500–$2,000 to create custom growth visualizations for pitch decks. Most importantly, it gives you data-driven insight into what's actually driving adoption — so you can double down on what works instead of guessing. If tracking your project's growth has been costing you time or credibility with investors, this tool pays for itself immediately through saved hours and better decision-making.
