fix(build,dev,info): name the server builder instead of assuming Nitro - #1671
…d the server
The startup banner and the dev UI's info view listed the installed Nitro
version even when another server builder, such as @nuxt/vite-server, was
configured. The banner now checks the configured server builder, and the
dev server reports the app's builders to the dev UI, which also lets the
info view name the configured app builder instead of assuming Vite.

Install footprint and published tarball
Each version installed on its own into an empty project with nothing but @nuxt/cli as a dependency, so the tree is exactly the CLI and its transitive dependencies. npm cache is warm and the registry is only consulted for metadata, so install wall time is indicative, not a network benchmark.

Interleaved runs on a shared runner: trust the deltas, not the absolute timings. The dev, restart and build suites run locally via pnpm bench:cli.
System calls cannot be simulated consistently and are left out of the measure. The reported value understates the real cost. Switch to the Walltime instrument to measure them.
nuxt info printed the installed Nitro version even for apps built with
another server builder. It now prints a Server builder row in the same
name@version form as Builder: nitro@2.13.6 by default, or the package
server.builder names, such as @nuxt/vite-server@4.6.4. In --json the
nitroVersion key becomes serverBuilder.

fix(dev,build): leave Nitro out of the versions when it does not build the server
fix(build,dev,info): name the server builder instead of assuming Nitro
Nov 9, 2026
The dev server now sends server-builder and Nitro metadata to the dev UI, which uses it when displaying versions. The nuxt info output reports the server builder instead of a standalone Nitro version. The startup banner omits the Nitro version when the configured server builder is not Nitro.
The server-builder display changes are mergeable after normal checks. A narrowly named custom builder could be mislabeled, but the supported first-party Vite output behaves as tested.

…fter building
nuxt info now reads the 'vite' and 'nitro' shorthands Nuxt accepts for
server.builder as the packages they stand for, so it no longer reports
the vite package's version for @nuxt/vite-server. The dev server also
reports the stack again once Nuxt has built, because a server builder
defined inline only describes itself while it builds.

Declare a Nitro version in the fixture
When no Nitro or Nuxt installation is reachable from the temporary project, the command returns nitro without a version. This assertion then fails and breaks the test suite.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Include the Vite server-builder version.
When server.builder is vite or @nuxt/vite-server, this return reports only vite, even if @nuxt/vite-server has a resolvable version. Both nuxt info output formats therefore omit the version shown in the PR objective. Resolve @nuxt/vite-server for both spellings, append its version when available, and update the assertion in packages/nuxt-cli/test/unit/commands/info-run.spec.ts Line 115.
