Display the date of creation and maintenance status for GitHub repositories.

Stop guessing whether a GitHub repository is a battle- tested titan or a project abandoned years ago.

GitHub Date of Creation seamlessly adds repository creation dates, maintenance status, and maturity badges directly into the GitHub UI. Originally a popular Chrome extension, this tool has been completely rewritten from scratch as a lightning- fast, zero- dependency userscript.

🔥 Features

Maturity Badges (The Lindy Effect): Quickly assess project age with visual indicators next to the date.

🌱 Sprout (< 1 year)

🌿 Established (> 1 year)

🌳 Mature (> 5 years)

🏛 Ancient (> 10 years)

Omnipresent Insights: Dates are not only on the repo page. They are added asynchronously into Search Results and Trending pages, saving you countless clicks.

Maintenance Status: View exactly when the repository was last pushed. Identify inactive projects instantly.

Historical Context: Receive fun, contextual timestamps (e. g., "Created around the time React 0. 0.3 launched!").

Blazing Fast: No moment. js, no jQuery, and no bloat. Uses native Intl APIs, a debounced DOM mutation observer to keep your browser smooth, and parallel fetching to avoid network delays.

⚙ How to Access Settings (Important!)

This script has a built- in, dark- themed settings modal. To access it:

1. Open any page on GitHub.

2. Click your Tampermonkey / Violentmonkey extension icon in your browser toolbar.

3. Click " ⚙ Settings" under the script name.

From here, you can toggle relative/absolute time, customize the exact date format, and add a Personal Access Token.

⚠ Beating the GitHub API Rate Limit

By default, GitHub limits unauthenticated API requests to 60 per hour. If you browse many search results, you' ll reach this limit quickly, and the dates will stop displaying.

The Fix:

1. Generate a free GitHub Personal Access Token (PAT) (You do not need to select any scope boxes; a blank token works perfectly).

2. Open the script Settings (via the Tampermonkey menu).

3. Paste your token and click Save. Your limit is now 5, 000 requests per hour.
