The catalogue, by the evidence it rests on
A listing is counted once, on the route its evidence takes. The share is of the 990 listings above the catalogue's completeness floor, the same rows every other count on this site uses.
| Route | Listings | Share | Definition |
|---|---|---|---|
| npm package | 790 | 79% | A catalogue listing whose evidence is an npm package at a pinned version, read as text from the registry's own tarball. |
| PyPI package | 133 | 13% | A catalogue listing whose evidence is a PyPI package at a pinned version, read as text and checked against the digest PyPI publishes. |
| Repository read at a commit | 67 | 6% | A catalogue listing for a hosted server, whose evidence is its public source repository read at a named commit. |
| Maker-submitted, run in the sandbox | 0 | 0% | A listing a maker submitted, scanned and run in an isolated sandbox, with a signed receipt. |
