Notes on sveltejs/sapper

How many stars does sveltejs/sapper have?
GitHub currently reports 6,916 stars for sveltejs/sapper. The chart itself is rebuilt from historical star data, which records star actions and not unstars, so it reads as an attention signal rather than a net star count.
What does recent star activity look like for sapper?
gitdebt observed about 8 public star actions for sveltejs/sapper over the latest 90 days of archive coverage (about 4 in the latest 30). This is an approximate attention signal, not a net-star count, because unstars are not present. That's below its lifetime average activity pace, which is common for mature projects.
Is sapper still active?
Public archive data shows about 4 star actions for sveltejs/sapper in the latest 30 days of coverage. For repository activity, use the commit heatmap, commit trend, and contributor charts on this page.

Light and dark variants, alt text, and one provenance line. Provenance is text in your README, never baked into the image URL, so the chart stays cacheable.

Paste it into Claude Code, Cursor, Codex, or any coding agent with your checkout open. It carries the measured numbers, the exact snippets, and the rules — including replacing an existing star-history widget in place rather than stacking a second chart under it.
