Third‑Party Script Budgeter

Find, measure, and control third‑party scripts and styles on your site. Quickly list external JS/CSS, estimate sizes, flag blocking scripts, and group by domain to spot heavy vendors.

Quick Start

npm install
npm run dev
# open http://localhost:3000

API

GET /api/budget?url=https://example.com

Responds with JSON summary: resource list, totals, and per‑domain aggregates.

Notes

• Sizes are best‑effort via HEAD content-length (may be null if not provided).
• Blocking script = script without async/defer/module attribute.
• Private network and non‑HTTPS targets are rejected.

Roadmap

• Har-like waterfall estimates via Preload/Resource Hints
• Budgets and allowlists with pass/fail
• CSV export and copyable remediation checklist
• Duplicate library detection (same pkg across vendors)
