vuejs/core

Choose this fork only if you need its release/tooling customizations or runtime-dom experimentation. If you want a current Vue core baseline, upstream is the safer default because this fork is stale and heavily diverged.

Prefer this fork only if you specifically need its local Vue-core modifications and are willing to absorb merge and testing debt. If you want a current, well-supported Vue base with the broadest upstream compatibility, upstream is the safer choice.

Prefer this fork only if you need its release/workflow automation or you are intentionally building on a customized Vue core. If you want a stable base that tracks current Vue fixes and compatibility work, upstream is the better choice.

Prefer upstream unless you specifically need this fork’s customized runtime/tooling behavior and can absorb the maintenance burden. This fork is for owners of a bespoke Vue stack, not adopters who want current Vue compatibility.

Prefer this fork if your goal is learning or teaching Vue internals, not adopting a current framework baseline. For production work, upstream Vue core is the better choice because this fork is stale and heavily diverged.

Prefer this fork only if you specifically need its older, customized Vue core behavior. If you want current Vue features, fixes, and tooling, upstream is the better default.

Choose this fork only if you need the specific customizations it carries and can afford to maintain a divergent framework codebase. If you just want Vue with current upstream fixes, the main repository is the safer choice.

Prefer this fork only if you want a study-oriented, heavily annotated Vue snapshot with custom size-check tooling. If you need a production Vue base, the fork is too stale and too divergent from upstream.

Prefer this fork only if its local compiler/SFC and workflow changes are exactly what you need and you are willing to own a stale, highly divergent codebase. If you want current Vue behavior, ecosystem compatibility, or low-maintenance adoption, upstream is the better choice.
