Real downloads for the top 300 Rust crates
Deciding whether to depend on a crate? Each page gives a plain verdict from 4 stated rules, the real downloads under the release spikes, who depends on it, and the alternatives. Method from our crates.io study, featured in This Week in Rust #674.
300 crates. Enter opens the first match.
Short answer31 of these 300 crates have 10,000+ dependents; 171 shipped no version in the 90-day window and 39 none in 2+ years. Among those that shipped, the median crate got 3% of its downloads within 2 days of a release, and for 91 of them release days ran less than 15% above normal. The whole field rose +36% from late summer to October, so we judge each crate's trend against the field.

Method and limits
Release window = the day a version was published plus the next day (crates.io timestamps, UTC). Baseline (real downloads a day) = median downloads over the other days. Quiet days still include CI and caches, so the baseline is an upper bound on people, never a head count. Verdicts use 4 rules: dependents, trend against the field, release spikes and release recency (listed on every crate page). A crate gets a page with 80+ days of data and 10,000+ all-time downloads. Data from the public crates.io API at one request every 2 seconds (data access policy); last fetch Oct 24, 2026. Why raw counts run high: The Manual.
