Open Source Surface

10% of the composite, when it applies 4 checks · 40 pointsconditional facet open_source

For providers whose product is itself open source ONLY: does the repository publish the maintainership surface a consumer needs in order to depend on it? A vulnerability-disclosure path, a documented contribution route, a published release history, and a stated code of conduct. Not applied to closed-source products — a company with no CONTRIBUTING.md is not deficient, it is differently shaped. Not applied where the repository could not be read, either: unreadable is not missing.

This facet is conditional. It is computed for every provider so its panel can render, but it enters the composite only where it applies — 1,126 of the 27,504 scored providers in the catalog. The counts on this page are over that population, not the whole catalog, and everyone else is neither measured against it nor penalised for it. The applicability rule and the composite arithmetic are on the rubric page.

How it is scored

4 checks worth 40 points, grouped by the artifact each one reads. A facet's sub-score is its awarded points normalized against the points that were actually applicable to that provider — a check needing an artifact the provider does not publish at all is N/A, and leaves both sides of the fraction.

Open Source Surface · open_source
CheckRulePoints
Published vulnerability-disclosure pathWhere an integrator reports a vulnerability in the thing they just put into production. The rarest of the four at 35.0% and the one that most directly affects a consumer, which is why it carries the most points.a SECURITY policy is present on the provider's own product repository14
Documented contribution routeWhether the project is actually open to participation or merely published. 62.4% coverage.a CONTRIBUTING guide is present on the provider's own product repository10
Published release historyVersioned, dated artifacts — the thing a consumer checks before depending on a project. Commonest of the four at 76.0%, but priced above the code of conduct because it carries far more information about whether the project is maintained.the provider's own product repository publishes releases10
Stated code of conductA stated standard for participation. Priced lowest of the four despite being rarer than releases at 49.6%: it is the most template-prone signal in the set, frequently dropped in wholesale, and so says the least about the project that holds it.a CODE_OF_CONDUCT is present on the provider's own product repository6

The other 7 facets

Move this number. Every provider in the catalog is profiled from a public repository at github.com/api-evangelist/<provider>, and each check above names the exact artifact it reads. Publish the artifact, open a pull request, and the next scoring run picks it up — no gatekeeping and no fee. The full rubric is at apis.io/rating/, and prioritized profiling is the fast lane if you would rather have it done for you.

Scored on rubric v0.17.2 across 27,504 providers · lists rebuilt 2026-09-01 · capped at the top 500 per page.
