Few direct dependents and gaining.
markup5ever: only 91 crates name it directly; most of its downloads come in through html5ever; downloads don't spike on releases.
How this verdict is decided (4 rules)
- Usage: crates.io reverse dependencies (crates that list it as a dependency): 10,000+ = foundational, 1,000+ = widely used, 100+ = established, under 100 = few direct dependents.
- Direction: the median quiet day in the last 30 days of the window against the first 30, read against the median tracked crate (the whole field moved +39% from late summer to October, so a raw trend says nothing). 10%+ ahead of the field = gaining; 10%+ behind = losing ground; otherwise steady. Steady with no release in 2+ years = quiet for years.
- Release spikes: the median release-window day against the quiet-day baseline: under 1.15x = no spike, 1.15x to 1.3x = small bumps, 1.3x or more = jumps on release days.
- Release recency: days since the newest version that was not yanked, from crates.io publish times.

The numbers in one paragraphmarkup5ever got 48,421,592 crates.io downloads from Jul 27, 2026 to Oct 23, 2026. 2% of them landed within 2 days of one of its 1 release. On the other 87 quiet days it got a median of 511,767 a day, about 3,582,369 a week. Capping release days at that baseline leaves 48,404,637 release-adjusted downloads for the window.
What this means if you're choosing a dependency
- You rarely add this one yourself. Only 91 crates name it directly; its downloads arrive through html5ever.
- Actively released. 0.40.0 shipped 43 days ago (Sep 11, 2026).
- Still pre-1.0 (0.40.0). Under Cargo's semver rules a 0.x minor bump may break you, so pin the minor version (
markup5ever = "0.40") and read the changelog on upgrades. - Fit check: license MIT OR Apache-2.0, edition 2021, needs Rust 1.85 or newer (from the latest version's manifest).
- Compare it by the baseline, not the raw count. 2% of its 48,421,592 downloads in the window landed within 2 days of a release; the steady number is 511,767 a day.

How we compute this
crates.io counts every download, including CI runners, mirrors and bots that fetch each new version, so raw counts run high (why, in The Manual). We split the last 89 days into release windows (the day a version of markup5ever was published, plus the next day) and quiet days, and use the median quiet day as the baseline: an upper bound on steady use, never a head count. The method and data come from our study of 90 days of crates.io data from 69 crates, featured in This Week in Rust #674; check any crate live with the real-downloads checker.
