Stacks, fragments and dependencies ranked by new projects over the last 7 days, 28 days and as far back as the weekly history reaches, with the change against the period before beside each count. The 7-day view also marks the entries the API counts as trending: at least 10 projects this week and a score of 1.5 or more against its average week of the prior 28 days.

Trending measures growth in use, not whether a stack works. Each stack's page shows its verification outcomes.

Showing the last 28 days, 3 Oct 2026 to 30 Oct 2026. Other ranges need JavaScript.

Projects per week, by fragment

The 6 fragments with the most projects in the last 28 days, week by week over the last 12 weeks. Fragments overlap across projects, so their lines are not stacked.

The dependency with the most new additions in the last 28 days, react, and which major versions its projects report. The range control changes only this history.

react (npm): major versions over time

Share of reporting projects on each major version, 5 weekly points from 27 Sept 2026 to 25 Oct 2026.

Each point is the share of projects reporting this package in the 28 days before it. A hidden major's share is missing, not zero, and the others are not rescaled to fill it.

Dependencies, last 28 days

Dependencies report the last 28 days through 30 Oct 2026; the range control changes only the version history. New additions are packages newly reported by projects that already reported dependencies before the window, and include packages added by applying a fragment that declares them. Counts, never rates.

How starts and trends are measured

Starts are adjusted counts from CLI telemetry, rounded to 5. Only installs seen at least 24 hours before a project starts qualify. Each period counts at most three projects per install and is capped at three times the distinct networks. Counts below five are hidden, not zero.

Trending means use has risen against that stack’s or fragment’s own recent baseline: at least 10 starts in the last 7 days and a score of 1.5 or more. The score is (last 7 days + 5) / (prior 28 days ÷ 4 + 5). It measures growth in use, not quality.

Computed 31 Oct 2026, through 30 Oct 2026. Numbers describe stacks projects, not the ecosystem.
