prometheus/blackbox_exporter has 5.9k stars and gained +32 of them in the last 30 days, a 0.5% change. It is written in Go, grouped under observability, released under Apache-2.0. A merged pull request waits a median of 5.2 days from opening to merge, measured on 39 pull requests. Last pushed on 26 Oct 2026.
Star growth per time window: stars gained, growth percentage, the star count at the start of the period, and whether the figure was measured from our own two-hour intraday snapshots, daily snapshots, or GitHub’s rebuilt star history, for the last 6 hours, the last 12 hours, today, the last 7 days, the last 30 days, and the last year. A period with no current measurement is left blank rather than shown as zero.

A period with no current measurement is left blank: a delta needs a measurement at both ends of the period. The 6- and 12-hour periods need two intraday measurements exactly that far apart, the day-and-longer periods need snapshots on both dates, and the last year also needs star history from a year ago, which we keep for one year.

A Reddit search for github.com/prometheus/blackbox_exporter runs while this page is rendered, at most once every 6 hours per repository. What it finds is stored in our database (25 posts per fetch, at most 200 repositories a day), so the numbers on this site can be reproduced later. Reddit's feed has no scores or comment counts, so none are shown.

Star history
Weekly, from GitHub's stargazers history, over a 30-day window.
Shares topics with
Repositories that share at least two topics with this one: most shared topics first, then stars gained in the last 24 hours.
Stars: 5.9k when it entered our index, 5.9k on the last capture we hold (24 Oct 2026), so +22 in that span. That span is our own measurement window, not a claim about what happened before it.
It has never shown up on GitHub Trending while we were watching, so there is no arrival to compare against.
Where it stands
Every position is against the 59,266 repositories measured today — not global GitHub figures.
