A blazing-fast, multi-platform library for analyzing webpage quality with **115 metrics** (92 HTML-based + 23 network-based) organized across **7 categories**, with **8 professionally-tuned profiles** for different page types.
> **⚠️ Breaking Change in v1.0.2**: Product profile reverted to e-commerce focus. Software/SaaS pages should use "general" or "homepage" profiles instead. See [CHANGELOG.md](CHANGELOG.md#breaking-changes) for migration guide.

```rust
use webpage_quality_analyzer::analyze;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let report = analyze("https://example.com", None).await?;
println!("Score: {}/100, Quality: {}", report.score, report.verdict);
Ok(())
}
```
### JavaScript/TypeScript (WASM)
```bash
npm install @webpage-quality-analyzer/core
```
```javascript
import init, { WasmAnalyzer } from '@webpage-quality-analyzer/core';
await init();
const analyzer = new WasmAnalyzer();
const report = await analyzer.analyze('<html>...</html>');
console.log(`Score: ${report.score}/100`);
```
### C++
```bash
wget https://github.com/NotGyashu/webpage-quality-analyser/releases/download/v1.0.0/cpp-package-v1.0.0-linux-x64.tar.gz
tar -xzf cpp-package-v1.0.0-linux-x64.tar.gz
```
```cpp
#include "webpage_quality_analyzer/webpage_quality_analyzer.hpp"
int main() {
auto report = wqa::Analyzer::analyze("https://example.com");
std::cout << "Score: " << report.score() << "/100" << std::endl;
return 0;
}
```
### CLI Tool
```bash
# Linux/macOS
wget https://github.com/NotGyashu/webpage-quality-analyser/releases/download/v1.0.0/wqa-cli-v1.0.0-linux-x64.tar.gz
tar -xzf wqa-cli-v1.0.0-linux-x64.tar.gz

## 🌟 Key Features
### 3-Tier API Design
**Level 1: Simple** - One function call
```rust
let report = analyze("https://example.com", None).await?;
```
**Level 2: Builder** - Custom configuration
```rust
let analyzer = Analyzer::<DefaultRuntime>::builder()
.with_profile_name("news")?
.enable_linkcheck(true)
.build()?;
```
**Level 3: Config Files** - YAML/JSON/TOML
```rust
let analyzer = from_config_file("config.yaml")?;
```
### Advanced Customization
**Adjust Metric Weights**:
```rust
analyzer.with_metric_weight("word_count", 1.5)?
.with_metric_weight("readability_score", 2.0)?
```
**Custom Penalties & Bonuses**:
```rust
analyzer.add_penalty_below("word_count", 300.0, 10.0)?
.add_bonus_above("readability_score", 80.0, 5.0)?
```
**Output Filtering** (98.8% size reduction):
```rust
let compact_report = analyzer.run_compact(url, html).await?;
```
### Batch Processing
**Parallel Analysis** (up to 180+ pages/second):
```rust
let reports = analyze_batch_urls_parallel(urls, None).await?;
```
**High-Performance Mode**:
```rust
let reports = analyze_batch_high_performance(urls).await?;
```

## 📈 Performance
Benchmarked on typical webpages:
| Small (<10KB) | 92 HTML | <100ms | <10MB | 200+ pages/s |
| Medium (50KB) | 115 Full | <500ms | <15MB | 150+ pages/s |
| Large (100KB+) | 115 Full | <1000ms | <20MB | 100+ pages/s |
**Optimizations**:
- ✅ DOM caching (elements cached, reused 115 times)
- ✅ Connection pooling (persistent HTTP connections)
- ✅ Parallel batch processing (Arc<Semaphore>, max 10 concurrent)
- ✅ Zero-copy metric scorers (Arc<dyn MetricScorer>)
- ✅ Optimized JSON serialization (field selectors)
