Hello, vx

A developer released vx, an MIT-licensed task runner and content-addressed build cache for JavaScript monorepos built on Bun, with no paid cloud dependency. In a demonstration, eight tasks across four packages ran cold in 879ms and then completed fully cached in 26ms, a 34× speedup, with configuration handled through a vx.workspace.ts file.

vx runs and caches a task graph, correctly, and stops there. It is a task runner and a content-addressed cache for JavaScript monorepos, built on Bun, with nothing hidden behind a paid cloud. Eight tasks across four packages, run cold, then run again with nothing changed: bash $ vx run build test --all --force result 8 tasks · 0 cached 0% · 879ms $ vx run build test --all result 8 tasks · all cached · 2.06s saved · 26ms The second run is 34× faster, because every key matched and every output was already on disk. A cold run spends its time in your tools, not in the runner. vx.workspace.ts .
