pnpm dlx always fetches a fresh package while pnpm exec runs the project's local binary

The two commands look interchangeable and are not. pnpm exec runs a binary from the project's node_modules/.bin, fails if it is not installed, and therefore uses the version the lockfile pins. pnpm dlx ignores the project's dependencies, downloads the named package into a temporary store, and runs it.

That makes pnpm dlx the equivalent of npx for one-off tools, and the wrong choice inside a package script, where it introduces an unpinned network fetch into every run. It is also the reason a script that works locally can pick a different major version on a machine with a cold cache.

pnpm run and bare pnpm <script> both resolve local binaries the same way pnpm exec does, so scripts need no prefix at all. When a one-off tool is genuinely wanted, pin it: pnpm dlx tool@1.4.0. pnpm caches dlx downloads, so repeated invocations of the same pinned version do not re-fetch.
