OAI/OpenAPI-Specification

Prefer this fork only if you need its historical 2.0 planning direction or its local fixtures/examples. For most adopters, upstream is the better choice because this fork is stale, far behind, and materially divergent.

Prefer this fork only if you specifically need its SmartAPI-specific schema and fixture customizations. For most adopters, upstream is the better choice because this fork is heavily behind and likely missing current spec and workflow improvements.

Prefer this fork only if you specifically need an old, stable OpenAPI snapshot or have legacy customization already built on top of it. For active spec work, tooling, or adoption today, upstream is decisively better.

Prefer upstream unless you specifically need legacy Swagger-era content. This fork looks like an archival, heavily outdated branch with limited practical value for new OpenAPI work.

Choose upstream unless you explicitly need a frozen snapshot. This fork offers no added functionality and is significantly behind, so it is best treated as an archival or personal baseline rather than a practical adopter choice.

Prefer upstream for almost any active use. This fork only makes sense as a frozen reference or archival copy; it offers no added functionality and is far behind the canonical repository.

Choose this fork only if Russian-language accessibility is the priority. For anything that depends on current OpenAPI spec text, schema accuracy, or active maintenance, upstream is the safer choice.

Prefer upstream unless you specifically need this fork's old issue-template customization or example-file tweaks. It is too stale to trust as a current OpenAPI Specification source, but it may still be useful as a historical snapshot or for very narrow workflow purposes.
