What is a GitHub stargazer?

Starring saves a repo to a developer’s list of stars so they can find it again, and it signals that the project is worth their attention. It is the most common way developers keep track of tools they like or want to try.

Because a star is a deliberate, public action, a repo’s star list is a roster of people who raised their hand about that project on purpose.

A watcher subscribes to a repo’s activity and gets notified about issues and releases. A fork is a full copy of the code someone made to build on or contribute back. A stargazer simply bookmarked and endorsed it.

Stars are the lightest and most common of the three, which is exactly why the star list is the broadest, most useful signal of interest in a project.

A star is opt-in intent. The developer went looking, found the tool, and flagged it. That is a warmer starting point than a bought list of strangers, because the first line of a message can name the exact repo they starred.

The catch is that the star list is just usernames. To act on it you need the named person behind each one. WarmStars scans a repo’s stargazers into named profiles with company, role, and a public email for many of them, using public data only.
