GitHub Stargazers Checker is a focused, free online tool that reports the public stargazer health of a GitHub repository: total stargazers, stars added over a chosen period, growth rate, forks, watchers, open issues, recent stargazers, and a stargazer growth timeline. Paste a repository URL or owner/repo into the primary input, run the check, and copy or download a dated report — no sign-in required.
Check any repository's stargazer health
On the first screen, paste a GitHub repository URL or an owner/repo string into the Primary input, pick a time range and contributor sort, and run the check. The GitHub Stargazers Checker reports total stargazers, stars added in the selected period, the growth rate, forks, watchers, open issues, top contributors, and a stargazer growth timeline. Read the dated evidence report in the output panel, then copy it as text or export it as JSON.
How to check a repository's stargazers
Paste a GitHub repository URL (for example https://github.com/owner/repo) or a bare owner/repo string into the primary input and run the check. GitHub Stargazers Checker reports the total stargazers, the number of stars added within the selected time range, the period-over-period growth rate, forks, watchers, open issues, recent top contributors, and a stargazer growth timeline. Every finding is reported as evidence with a stated limitation, so you can tell a verified figure from a simulated estimate.
How recent and growth are measured
The time-range selector on the first screen lets you choose last 90 days, last 180 days, last year, or all time. The growth rate is computed as stars added in the period divided by the total at the start of the period. The timeline renders deterministic per-week star additions so you can see acceleration or a plateau at a glance.
What every report contains
A report always records the repository input, the checks performed, the observed metrics with status and detail, the timestamp of the run, and the limitations of the check. Reports are generated deterministically in the browser from public metadata and can be copied as text or exported as JSON for your own records.
How your inputs and reports are handled
All analysis runs locally in your browser against public metadata fixtures. No account, sign-in, or payment is required. If the live evidence service is unreachable, the tool clearly labels the run as a local deterministic simulation so the report never overstates what was verified. You decide what to do with a report — the tool never publishes anything on your behalf.
Frequently Asked Questions
What does the GitHub Stargazers Checker measure?
It reports total stargazers, stars added within the selected time range, the growth rate, forks, watchers, open issues, recent top contributors, and a stargazer growth timeline for a public GitHub repository.
Do I need a GitHub account or a token?
No. Paste a repository URL or owner/repo and run the check. No account, token, or payment is required, and the tool runs from the first screen.
How current are the stargazer numbers?
Results reflect the public metadata observed at the time of the run. Each report carries a timestamp and states the limitations of the checks it contains so stale or unverifiable figures are not presented as fact.
Why is a run sometimes labelled as a simulation?
When the live evidence service is unreachable, the tool uses deterministic local metadata and clearly labels the run as a simulation so the report never overstates what was verified.
Can I keep or share a report?
Yes. Every report can be copied as text or exported as JSON from the output area. The tool never posts a report anywhere; sharing is always your own action.
