# katproxy
A sleek, minimal, high-performance proxy list stream & active TCP latency prober.
Features dark glassmorphism aesthetics, live SVG countdown timer, one-click copy suite (IP:Port, cURL, raw lists), multi-protocol filtering (HTTP, SOCKS4, SOCKS5), and live round-trip latency metrics.
---
## ⚡ Architecture
- **Backend (Android Tablet / Termux)**:
- Aggregates thousands of proxies from premier GitHub sources (`monosans/proxy-list`, `TheSpeedX/PROXY-List`, `hookzof/socks5_list`).
- Active background TCP socket connection tester measuring real round-trip latency (`ms`).
- REST API running on port `5050`, tunneled via Cloudflare Tunnel as `katproxy-api.oiupoyt.space`.
- **Frontend (Cloudflare Pages)**:
- Fast, zero-dependency static web application located in `public/`.
- JetBrains Mono typography, smooth 60fps micro-animations, quick actions, responsive on desktop and mobile.
---
## 🚀 API Endpoints
| Method | Endpoint | Description |
|---|---|---|
| `GET` | `/api/health` | Service health status and uptime |
| `GET` | `/api/stats` | Total proxies, verified alive count, protocol counts, avg ping |
| `GET` | `/api/proxies` | Paginated list with `protocol`, `alive`, `search`, `sort`, `country` filters |
| `POST` | `/api/refresh` | Trigger immediate upstream re-fetch and probe cycle |
| `GET` | `/api/raw` | Raw plaintext list (`ip:port` or `format=url`) for curl / bash pipelines |
### Examples
```bash
# Get 5 fastest SOCKS5 proxies
curl "https://katproxy-api.oiupoyt.space/api/proxies?protocol=socks5&alive=true&limit=5"
# Raw IP:PORT stream for CLI scripts
curl -s "https://katproxy-api.oiupoyt.space/api/raw?protocol=socks5&alive=true" | head -n 10
```
---
## 🛠 Cloudflare Pages Deployment (Frontend)
1. Connect this GitHub repository (`oiupoyt/katproxy`) to Cloudflare Pages.
2. Build Settings:
- **Framework preset**: None
- **Build command**: None (leave empty)
- **Build output directory**: `public`
3. Deploy! The frontend automatically connects to `https://katproxy-api.oiupoyt.space`.
---
## 📱 Tablet Backend Setup
```bash
# On the tablet (Termux)
cd ~
git clone https://github.com/oiupoyt/katproxy.git katproxy
cd katproxy/backend
npm install
node --max-old-space-size=256 server.js
```
