GitHub Date of Creation (v3.1.2)

A production-grade cross-browser extension that seamlessly injects project maturity insights directly into GitHub's UI. This is a modernized fork of the original extension, rebuilt for Manifest V3 with zero dependencies, cross-browser compatibility, and deep UI integration.

🚀 Key Features

• Project Maturity Badges (Lindy Effect):
  • 🌱 Sprout (<1 year)
  • 🌿 Established (>1 year)
  • 🌳 Mature (>5 years)
  • 🏛️ Ancient (>10 years)
• Interpretive Insights Cards (Tooltips): Hover over the injected sidebar badge to view exact creation and push timestamps along with explanations of the project's maturity status (Lindy Effect) and maintenance health metrics.
• Redesigned Options & Customizable Themes: Toggle between three different card visual themes (GitHub Native, Glassmorphism, and Compact) with a real-time interactive preview.
• API Rate Limit Quota Meter: Built-in request usage progress bar inside the options page to track your remaining GitHub API request quota.
• Cross-Browser Compatibility: Engineered to run natively on both Chromium-based browsers (Chrome, Edge, Brave, Opera, Vivaldi) and Mozilla Firefox / Firefox-based browsers (e.g. Zen Browser).
• Health Indicators: Integrated "Last push" status to differentiate between stable, long-term tools and abandoned legacy code.
• Search & Trending Support: Dates are injected directly into search results and trending pages—not just main repository pages.
• Performance First: Removed moment.js in favor of native Intl APIs, reducing memory usage and bundle size by 80%.
• Secure PAT Authentication: Automated setup for Personal Access Tokens to bypass the unauthenticated 60 requests/hour limit.

📸 Extension in Action

The userscript version includes all the same features — maturity badges, repository size, maintenance status, and per-repo refresh — without needing to install a browser extension.

⚙️ Configuration

• Rate Limiting: To avoid API errors, generate a Personal Access Token in your GitHub settings and paste it into the extension options.
• Date Format: Choose between native relative time or any custom formatting string (e.g., YYYY/MM/DD).
