Real World Testing — Wanted

▶ Watch the Real World Testing PV

[!WARNING]
Vize is experimental and in its Real World Testing phase — not a completely
production-ready toolchain yet. Breaking changes and behavior that diverges from Vue are
expected. Review the stability guide,
production-readiness checklist,
and support policy
before adopting it.

What Is Vize?

Vize is a Rust-native toolchain for Vue — one fast, vertically integrated lane
for single-file components. A single shared parser powers compilation, linting, type-checking,
formatting, and editor tooling, so your whole Vue workflow runs on the same high-performance core
instead of a patchwork of disconnected tools.

It plugs into where you already work: @vizejs/vite-plugin (Vite), the vize npm package
(project scripts and shared config helpers), the native vize binary (LSP / profiling /
specialized CLI workflows), @vizejs/vite-plugin-musea (Musea), and oxlint-plugin-vize
(Oxlint).

Everything lives in the documentation — start with
Getting Started.

Vize is in its Real World Testing phase: fix requests and PRs are very welcome, and we are looking for
reasonably large Vue projects to use as test beds.

Special thanks to:

• Blacksmith for sponsoring high-performance CI/CD runners and
  Testbox infrastructure for frequent benchmarks and real-project compatibility checks.
• Mates Inc. for allowing ubugeeei, its employee, to dedicate
  discretionary work time to OSS and for adopting Vize in the build for the company’s engineering
  website.
• OpenAI Codex for Open Source for supporting
  open-source maintainers through a program that helps keep critical OSS development moving.
• かっこかり for continuously testing Vize’s compiler and
  Vite Plugin on Misskey (~103k lines of Vue across 586
  SFCs), with timely reports as the implementation changed
  (report).
• ushironoko for compiler, linter, and CLI fix reports,
  reference implementations, and reproduction repositories.
• dannote for bringing Vize into the Elixir community through
  Volt, an Elixir-native frontend toolchain built on Vize,
  and for reporting missing pieces and sending PRs as Volt adopted Vize as a foundation.
• n13u and #frontend_phpcon_do for persistently reporting fix cases while
  building a Nuxt-based conference website with Vize, then carrying that validation all the way to
  production adoption
  (report,
  write-up).
• yamanoku for accessibility-focused feedback around Vize and for using the project in the Vue Fes
  Japan speaker-site migration documented in the v-tokyo Meetup #25 LT notes
  (write-up).
• sevenc-nanashi for using the
  VOICEVOX editor (~26k lines of Vue across 128 SFCs) as a
  real-world target for improving compiler precision
  (report).
• Everyone who has mentioned, shared, tested, or amplified Vize across the community.
