CachingEvery task has a key
Every task has a key
A task you never cache still has a key. Change its inputs and every cached task after it runs again, so you never get a build made for old inputs.

CachingPerformanceWhat a run does not do
What a run does not do
A run does no cleanup at exit, never walks the shared store, and shows no "time saved" it did not measure.
announcementWhat vx is, and what it refuses to be
What vx is, and what it refuses to be
vx runs and caches your task graph, correctly, and nothing else. How a run works, and what will never be inside.

Turborepo runs and caches. Nx adds a platform. vx is the runner with open plugin points, and nothing behind a paid cloud.

Performance, modularity, extensibility. In that order.
Three priorities in a fixed order settle every design choice in vx: performance, then modularity, then extensibility. Nine rules follow.
PerformanceNo daemon, and still quick when nothing changed
No daemon, and still quick when nothing changed
vx has no background process watching your files. A run with nothing to do stays quick, and it can never act on a stale view of the tree.
designExplicit over magical: why vx never guesses your inputs
Explicit over magical: why vx never guesses your inputs
vx never guesses what a task reads. A trace says what a task read once, after it ran. A cache key has to be right before the task runs.
ExecutionOne command per task; the shell is the API
One command per task; the shell is the API
A vx task is one shell command. That one rule is why remote runs, the sandbox and cache replay all work without special cases.
DXOne binary, nothing to install underneath
One binary, nothing to install underneath
vx ships as one self-contained file per platform. No Node to pick, no Bun to install, no daemon.
PluginsA plugin fills one stage, often in under 25 lines
A plugin fills one stage, often in under 25 lines
vx is a pipeline with a named hook at every stage. A plugin fills only the stage it needs, and most example plugins are under 25 lines.

Your machine is always the last place a task can run, and the local cache is always asked first. A dead remote never breaks a build.
