# Fake-Fast Lite
|
| 24 |
+
|
| 25 |
+
**Sniffs edge-cache lipstick on a slow origin.**
|
| 26 |
+
Not a lab suite—just fast receipts you can quote.
|
| 27 |
+
|
| 28 |
+
## What it checks
|
| 29 |
+
- **TTFB (approx.)**: streamed first-byte timing (ms).
|
| 30 |
+
- **Edge/CDN hints**: `cf-cache-status`, `via`, `x-cache`, `server-timing`, etc.
|
| 31 |
+
- **Caching**: `cache-control`, `age`, `etag`, `last-modified`, `vary`, `expires`.
|
| 32 |
+
- **DOM weight tells**: `<script>` count (inline vs external), stylesheet count.
|
| 33 |
+
- **Heuristic verdict**: “Looks Clean / Borderline / Likely Fake-Fast” + score (0–100).
|
| 34 |
+
|
| 35 |
+
> ⚠️ This is a **lightweight heuristic**. It won’t replace a proper lab test (WebPageTest, Lighthouse). It’s for fast triage and public-facing receipts.
|
| 36 |
+
|
| 37 |
+
## Why this exists
|
| 38 |
+
“Fast” homepages that feel slow as soon as you click anything? That’s **edge-cache cosplay**: CDN HITs masking a sluggish origin and script buffet. This tool gives you a quick smell test.
|
| 39 |
+
|
| 40 |
+
## How it works (short)
|
| 41 |
+
- Streams a GET and stops at first non-empty chunk for **TTFB**.
|
| 42 |
+
- Collects **headers** and scans HTML to count scripts and stylesheets.
|
| 43 |
+
- Aggregates into a **score** and plain-English **verdict**.
|
| 44 |
+
|
| 45 |
+
## Limits
|
| 46 |
+
- Some sites block HEAD/GET or require JS to render.
|
| 47 |
+
- TTFB is best-effort; networks vary. Use multiple runs.
|
| 48 |
+
- No JS execution; this is an HTML/headers sniff.
