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.
