Perf Budget Auditor
Audit your frontend build against a performance budget and catch size regressions before you ship.
What it flags
- Total and initial bundle over budget.
- Individual chunks over a threshold.
- Oversized images.
- Source maps shipped to production.
- Large unminified JavaScript.
How to run
Point it at a stats.json and a perf-budget.json you control. Read-only; it does not run the bundler.
Good to know
Heuristic. It reads a manifest and file sizes, not a live browser, so it is not Lighthouse.
Questions
What does it catch that a feature review misses?
A bundle creeping over budget or a stray source map shipped to prod.
Does it change anything?
No. It is read-only and flags issues for you to act on.
Hold the line on bundle size.
