Short answer
A star itself never disappears, but its value as a sales signal fades over months, not days. A developer is most reachable and most receptive in the weeks after they star, while the tool is still on their mind. A star from years ago is much colder, so recent stargazers are worth prioritizing.
No. Once a developer stars a repo, it stays starred until they unstar it. What decays is not the star, it is the context: the project they were evaluating, the problem they were solving, and the attention they were paying at that moment.
So the right way to think about it is signal freshness, not expiry. A recent star means someone is paying attention right now.
As a rule of thumb, the strongest window is the first few weeks to a few months. That is when the tool is freshest in the developer’s mind and a message that references it lands with real context. Beyond that, the person may have moved teams, finished the project, or simply forgotten why they starred it.
This does not make older stars worthless. It means recency is a ranking signal: reach the freshest stars first, because they convert the best per message.
GitHub records when each star happened, so a stargazer list can be ordered newest first. Working the most recent stars while they are still warm, then moving back in time, gets more out of the same list than emailing it in a random order.
WarmStars surfaces how recently each developer starred, so you can sort your outreach to the freshest signals and reach them before the moment passes.
