Your competitor’s stargazers are the most engaged users in your category, and the list is public. WarmStars scans any repo, including one you do not own, and turns each star into a named developer at a real company, so you can see exactly who is adopting the alternative.

See who is starring the competition.
Anyone can point WarmStars at a competing repo. The star list is open, and every star is a developer who went out of their way to bookmark a tool in your space. Scan it and the anonymous count becomes named accounts: which companies are trying the alternative, who champions it inside them, and a public email for many. That is a map of your market that no analyst report hands you.
Company lands next to every star, so you can build a named list of the companies adopting a competitor and hand it to sales as accounts worth a conversation.
starred_at shows when each developer bookmarked the repo, so a burst of recent stars tells you where a competitor is gaining ground before it shows up in a revenue number.
Save the accounts to a board, or export them to CSV or JSON. It is intelligence you can route, not a slide you screenshot.
Every scanned stargazer carries the context that decides whether an account is worth a look, and when a competitor started winning it.
emailA public, reachable address where the developer left one, so an account you spotted becomes a person you can reach.
companyThe account behind the star, so a competitor’s user base becomes a named list of companies, deduped against your own.
starred_atWhen the developer starred the repo, so you can watch a competitor’s momentum by the shape of their recent stars.
One star on a competitor’s repo becomes a named engineer at a real account: evidence of exactly who is shopping the alternative, and worth a call.
