These overlap but are not the same job: esbuild is a raw, ultra-fast bundler, while Vite is a full build tool that uses esbuild (and Rollup) internally.
esbuild (Go) is a low-level bundler/transpiler prized for speed. Vite is a higher-level build tool and dev server that uses esbuild for dev transforms and Rollup for production builds, adding HMR, plugins, and framework integration.

In CI
Most apps want Vite: it gives a complete pipeline (dev server, HMR, plugins, framework presets) and produces optimized Rollup builds while still using esbuild for speed. Reach for esbuild directly when you need a minimal, ultra-fast bundling/transpiling step in a script or tool and do not need a framework-aware build. In practice, using Vite already means you are leaning on esbuild under the hood.
Speed it up
Cache dependencies and the build cache keyed on your lockfile to avoid cold rebuilds. Both run the same on CI runners; faster managed runners shorten the build step on large apps.
Benchmark on your repository before choosing
Build-tool benchmarks published by vendors use repositories chosen to show a difference. Yours is the only one that matters, and both a cold and a warm measurement are needed because CI mostly runs cold.
Terminal
# cold: no cache, the CI condition
rm -rf node_modules/.cache dist && time <tool> build
# warm: the local development condition
time <tool> build
# and the one people forget: incremental after a one-line change
echo "// touch" >> src/index.ts && time <tool> build
The verdict
Building an app or framework project: Vite for the full, optimized pipeline. Need a minimal ultra-fast bundler in a script: esbuild directly. They are different layers - Vite already uses esbuild for you.
