Find out which third-party scripts are weighing your page down. No signup required.

Prerequisites

Playwright MCP (comes with Claude Code)

Trigger

"What third-party scripts are slowing my site?"
"Third-party bloat audit https://..."
"Which trackers are on my page?"

Workflow

Navigate to the URL using mcp__playwright__browser_navigate
Wait for load to settle, then pull every request with mcp__playwright__browser_network_requests
Classify each request as first-party (same registrable domain as the page) or third-party. Group third-party requests by their domain and sum transfer size + request count per domain.
Label well-known vendors by domain so the report is readable, e.g.:
- google-analytics.com, googletagmanager.com → Analytics / Tag Manager
- doubleclick.net, googlesyndication.com → Ads
- connect.facebook.net → Meta Pixel
- intercom, crisp.chat, hotjar, fullstory → Chat / Session replay
- optimizely, launchdarkly → A/B / Flags
Estimate main-thread cost: count third-party <script> resources and note any loaded synchronously in <head> (these block parsing). Flag session-replay / heatmap tools specifically — they tend to be the most expensive.
Output:

## Third-Party Bloat Report: [URL]

**18 third-party requests across 7 domains — 1.4 MB (44% of page weight)**

### Heaviest offenders
| Vendor                  | Size   | Requests | Note |
|-------------------------|--------|----------|------|
| Hotjar (session replay) | 620 KB | 5        | Loaded sync — blocks main thread |
| Google Tag Manager      | 310 KB | 4        | Fans out to 3 more tags |
| Intercom (chat)         | 280 KB | 3        | Could lazy-load on scroll |
| Meta Pixel              | 90 KB  | 2        | —    |

### Recommendations
1. Defer Hotjar until after `load`, or sample fewer sessions.
2. Lazy-load the Intercom widget on first scroll / click.
3. Audit GTM — it's pulling tags you may not still use.
