Star history

Loading star history…

Growth

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.
Period	Stars gained	Growth	From	Measured
Last 6 hours	—	—	—	Not measured
Last 12 hours	—	—	—	Not measured
Today	+68	0.2%	28.5k on 25 Oct 2026	Daily snapshots
Last 7 days	+311	1.1%	28.2k on 18 Oct 2026	Weekly history
Last 30 days	+1.3k	4.6%	27.3k on 27 Sep 2026	Weekly history
Last year	—	—	—	Not measured

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.

Stars: 27.5k when it entered our index, 28.6k on the last capture we hold (27 Oct 2026), so +1k in that span. That span is our own measurement window, not a claim about what happened before it.

We hold 16 mentions for it, the oldest dated 30 Oct 2025 and the first written into our database on 27 Oct 2026. Thread dates come from the source, not from when we fetched them.

Oh wow :) thank you for cmux, it's a great project! The code is here: https://code.pecheny.me/pecheny/cmux or if you prefer github, https://github.com/alexander-pecheny/cmux I think I only added two features, pasting images over mosh (ssh already worked but not mosh) and a compact version of sidebar. The story behind the fork is: I had a bug with raycast, filed a PR that fixed it for me https://g…

This is fun! I switched to https://github.com/manaflow-ai/cmux for a while, but had to switch back to Ghostty due to its unreliability, high memory and CPU usage and a bunch of bugs. This makes a lot of sense, but... it'd be great to allow pulling out of a canvas into a second canvas for those of us with multiple screens (you at least end up needing one window per screen). In general it feels lik…

A Reddit search for github.com/manaflow-ai/cmux 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.

Repositories in the same collection, of a comparable size (within 5× in stars) and from a different owner, that were discussed in the same threads. Same-owner projects are excluded because they are usually pieces of the same tool, not rivals. A repository also stays out if the two never met in a discussion.
