+minimal proxy list aggregator and live TCP latency prober.
 
 ↗ [katproxy.oiupoyt.space](https://katproxy.oiupoyt.space)
 
+## features
 
----
+- autofetches public proxy lists from multiple upstream sources
+- concurrent non-blocking TCP socket prober measuring live round-trip latency
+- clean, square brutalist dark interface with interactive constellation background
+- protocol filters (HTTP, HTTPS, SOCKS4, SOCKS5)
+- instant search, sort by latency, and alive-only filter
+- one-click copy for `host:port`, cURL commands, and proxy URLs
+- export full proxy lists as `.txt` or copy all visible to clipboard
+- auto-refresh timer loop with manual re-probe trigger
 
-## Overview
+## backend (rust)
-
-katproxy collects proxies from multiple public repositories (`monosans/proxy-list`, `TheSpeedX/PROXY-List`, `hookzof/socks5_list`), normalizes them, and runs concurrent TCP socket checks to verify responsiveness and record round-trip latency.
-
-The backend runs as a lightweight daemon on an Android tablet (Termux) exposed via Cloudflare Tunnel. The frontend is a static web app hosted on Cloudflare Pages.

-| Method | Endpoint | Parameters | Description |
-|---|---|---|---|
-| `GET` | `/api/health` | — | Service uptime and status |
-| `GET` | `/api/stats` | — | Total count, alive count, protocol breakdown, avg latency |
-| `GET` | `/api/proxies` | `protocol`, `alive`, `search`, `sort`, `limit`, `page` | Filtered and paginated proxy list |
-| `GET` | `/api/raw` | `protocol`, `alive`, `format` (`ip:port` or `url`) | Plaintext list for shell scripts and curl |
-| `POST` | `/api/refresh` | — | Trigger upstream re-fetch and verification cycle |

-# Stream raw IP:PORT pairs
+# run in development
-curl -s "https://katproxy-api.oiupoyt.space/api/raw?protocol=socks5&alive=true"
+cargo run
+
+# or run optimized release
+cargo run --release
 ```

-## Architecture
+## license
-
-- **Backend (`/backend`)**: High-performance Rust (Axum + Tokio) service running on port `5050`. Features non-blocking TCP socket prober and automated refresh background worker.
-- **Frontend (`/public`)**: Vanilla JavaScript, CSS, and HTML with JetBrains Mono typography, auto-refresh countdown, and one-click copy actions.
-- **Tunnel**: Managed by `cloudflared` routing `katproxy-api.oiupoyt.space` to `localhost:5050`.
