GitHub Stars
Total stars on the project's repository, which is a rough gauge of popularity among developers.
A GitHub star is a bookmark a developer adds to a repository they find interesting or useful. The total star count is a cumulative measure of a project's interest and recognition in the technical community. It grows slowly and reflects reputation rather than the current pace of work. A high number suggests a strong developer community, but it can be inflated artificially, so treat it as context rather than a standalone signal. Best read alongside the commit count (current activity).
In plain words
How many people on GitHub 'liked' (starred) the project's code. Many stars = the project is well known and respected among developers. It's a reputation measure that grows slowly. It doesn't tell you what's happening with the project today.
Example
Bitcoin Core and Ethereum have tens of thousands of stars, which is a mark of global recognition. A fresh project with 50 stars is only starting to build a developer community.
