Your repo’s stars
are people. Meet them.
A GitHub star looks like a number. It’s really a developer who chose to pay attention to your work. WarmStars turns that number into the named people behind it: who they are, where they work, how recently they starred, and a public email for the ones who left one. Meet the stars of your repo, then reach the ones worth reaching.

From a star to a name to a conversation.
A star is the warmest signal a developer gives you for free. WarmStars turns that quiet signal into a person you can understand and meet, in three steps.
Point it at a repo
Drop in any public repository: your own, a competitor’s, or any tool your buyers already use. WarmStars pulls the full stargazer list, however large.
owner/name or a github.com URL
Stars become people
Each star is matched to a real profile and enriched with company, role, location, influence, and how recently they starred, so a bare username turns into a person you can actually act on.

Meet the ones worth meeting
Filter by follower reach, repo count, or how recently they starred. Work the ones that matter on a built-in board, moving them through New, Contacted, and Replied with notes as you go, or export to CSV and your own tools. You reach out on your terms.

One scan engine, every job to do.
The signal each team reads differs. The repo you point it at differs. The output, a named audience of developers who already care, does not.

Warm only works if it’s clean.
Reaching a developer who raised their hand is the whole point, so the data behind it has to be public, traceable, and easy to opt out of. That isn’t a footnote here. It’s the design.
Publicly available sources
WarmStars surfaces information developers made public: public GitHub profiles, public commit metadata, and public package registries like npm. No private data, no logins bypassed, no lists bought from brokers.
Graded, never guessed
Every email carries a confidence tier, from verified down to likely, so you always know how sure we are. We never guess an address, and we never identify someone by their display name alone.
One list, honored every time
A built-in do-not-contact list is checked by both email and GitHub login before anything is returned. Anyone can remove themselves and stay removed across every future scan, or ask us to erase their data entirely, which we honor everywhere.
You send. You own it.
WarmStars gives you research, not a send button. You decide who to contact, and you are responsible for reaching out lawfully under CAN-SPAM, GDPR, and the rules where your recipients are. We never email anyone for you.
Export it, then it’s yours
Take everything as CSV or push it to your CRM. We don’t resell what you scan, and there are no per-contact unlock fees hiding behind the results.
Every star has a name. Go meet yours.
Point WarmStars at a repo, see the developers who raised their hand, and reach the ones who left a public door open. Your first two scans are free.
