GitHub Star History
Visualize the star growth trends of GitHub repositories, helping developers understand project popularity changes and analyze open-source project development trajectories.
Key Features
Beautiful Chart Display
Uses Chart.js to generate professional trend charts with modern dotted grid backgrounds and gradient fill effects. Charts support interactive hover showing cumulative star counts at specific time points.
Complete Data Retrieval
Retrieves complete star history records through GitHub API, including add time and user information for each star. Supports paginated data loading for large repositories with real-time progress display.
Monthly Data Aggregation
For smoother and clearer trend lines, the tool aggregates star data by month, displaying cumulative growth curves. This approach both reflects overall trends and avoids overly dense data points.
Chart Export
Supports exporting generated charts as high-resolution PNG images with filenames automatically including repository information. Exported images have white backgrounds, suitable for presentations, reports, or social media sharing.
GitHub Token Information
Why Tokens Are Needed
GitHub API has strict rate limits for unauthenticated requests (60 per hour). Using a Personal Access Token increases the limit to 5000 per hour, sufficient for retrieving complete star history of large repositories.
How to Obtain Token
- Log into GitHub account
- Visit Settings > Developer settings > Personal access tokens > Tokens (classic)
- Click Generate new token (classic)
- Enter descriptive name (e.g., "Star History Viewer")
- No permissions needed (public data requires no special permissions)
- Click Generate token
- Copy generated token (displayed only once)
Security Notice
Token is used only in your browser and never sent to our servers. All API requests go directly from your browser to GitHub. Keep token secure and don't share with others.

https://github.com/owner/repo - Example:
https://github.com/Ice-Hazymoon/MikuTools
- Format:
- In access token box, paste your GitHub Personal Access Token
- Click query button and wait for data loading
- Small repositories (<1000 stars): Completes in seconds
- Medium repositories (1000-10000 stars): 10-30 seconds
- Large repositories (>10000 stars): 30+ seconds
- View generated star history chart
- Click download chart button to save as PNG image
Chart Explanation
Axes
- Horizontal: Timeline showing years
- Vertical: Cumulative star count, automatically using K (thousand) or M (million) units
Data Points
- Each point represents cumulative star count at month end
- Hover shows specific date and star count
- Curve uses smooth interpolation for easier trend observation
Chart Title
Chart top displays repository's complete path (owner/repo); exported image filename also includes this information.
Important Notes
- Initial queries of large repositories may take longer; please be patient
- GitHub API has rate limits; frequent queries may encounter limit warnings
- Private repositories require tokens with appropriate permissions to access
- Data aggregated monthly, doesn't show daily detailed changes
API Limits
Using Personal Access Token, GitHub API limit is 5000 requests per hour. Querying one repository may require multiple requests (depending on star count); please plan query frequency reasonably.
Privacy Protection
This tool calls GitHub API directly from your browser without going through any intermediate servers. Your access token and query history are not recorded or stored.
Tool Comparison
Compared to online services like star-history.com, this tool provides more flexible customization options and offline export functionality. Compared to manual statistics, this tool offers high automation, good visualization, and complete accurate data.
