01 Build intelligence / 2026

Know what
your build ships.

A small, repeatable lab for comparing JavaScript build systems. Every number is generated from the same fixture, on the same machine, with the measurement trail left intact.

The short version

Build time is only half the story. BuildScope puts fresh-build speed, repeat-build speed, and the weight of the final artifact next to each other—so a fast command never hides a heavy result.

Lab note / 041

Keep the fixture boring.

One entry point, 36 small modules, identical output targets. The point is not to make a tool look clever; it is to make the comparison easy to rerun.
