Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.

Signal	Value	What it measures	Window	Observed	Source
GitHub stars	1	Number of GitHub accounts that bookmarked this repository since it was created. It is a bookmark count, not installs, not active users and not quality.	cumulative, all time	2026-08-06	GitHub
Last commit	2026-07-30	Date of the most recent push to any branch. This is the strongest cheap indicator of whether the project is still maintained.	point in time	2026-08-06	GitHub
Open issues	8	Open issues plus open pull requests, as GitHub counts them together. A high number can mean an active project or an abandoned one.	as of fetch	2026-08-06	GitHub

These share tags the maintainers applied themselves, such as dns, osint, reconnaissance, security. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
