GitHub stars are a vanity metric. Before you raise the pitchforks, here us out.
They feel great, photograph well, but tell you almost nothing about whether anyone actually uses your project. A star is basically an applause, but not actually product adoption.
We've worked with dozens of dev-focused companies and the ones with genuinely healthy OSS projects have stopped putting star counts on the slide. They track three behaviors instead:
1. Package downloads and active installs (npm, PyPI, Docker pulls). Someone pulled the code onto a machine. That's a decision, not a bookmark.
2. Issue signal-to-noise. Repeat contributors filing real bugs = people running you in production and hitting the sharp edges. Drive-by reactions mean nothing.
3. Time-to-second-PR. First PRs are curiosity, second PRs are commitment. In the healthy projects we've measured, a returning contributor shows up inside 30 days. In the dead ones, they never do.
Stars tell you people noticed, but these three will tell you they really cared.
