Spec churn index ​

How often does a new version of a provider's published API description break a client written against the one before? SHAPI replays the whole history of the [APIs.guru openapi-directory](https://github.com/APIs-guru/openapi-directory), the largest public collection of OpenAPI specs, and diffs every spec against its previous version.

Directory commit: [f04b8d0bcd39](https://github.com/APIs-guru/openapi-directory/commit/f04b8d0bcd39c52e1cf3ad7a5fe744709832ae49) (2026-04-20, CC0-1.0).

Totals: 103,799 spec edits across 5,818 spec files. 102,455 version pairs compared, and 7,714 of them breaking.

What counts as breaking ​

A new version is breaking when it does at least one of these, compared with the version before:

  • removes an operation;
  • removes a 2xx response;
  • removes a parameter, or requires one that was optional or new;
  • removes a response property or a schema;
  • changes a property's type;
  • removes an enum value.

Added enum values and new error statuses don't count here. The diff is the one SHAPI's spec-history replay uses, with Swagger 2.0 specs mapped onto OpenAPI 3 first.

Ranking ​

Providers with at least 10 version pairs, ranked by the low end of the 95% interval of their breaking rate, so a provider with a few versions doesn't outrank one with hundreds by chance.

Limits ​

  • The directory is a mirror. A version here is one APIs.guru commit, not necessarily one provider release. Several releases can land in one commit, and a commit can re-render a spec the provider didn't change. Specs whose description only changed form compare as equal.
  • A spec is not the API. It describes what the provider says the API does. A behaviour change that the spec doesn't mention is invisible here, which is what SHAPI's canaries are for.
  • Not every spec is compared. Added, renamed and deleted spec files have no previous version to compare against. Specs over 3 MB (601 versions) and versions that don't parse (445) are skipped.

Reproduce it ​

bash
git clone --no-checkout --single-branch https://github.com/APIs-guru/openapi-directory.git packages/bench/.cache/apis-guru
pnpm --filter @shapi/bench bench:spec-churn

The script is packages/bench/scripts/spec-churn.ts. It writes packages/bench/results/spec-churn.json, which this page shows.
