Find Me Internet 🌐

Find Me Internet is a high-performance, scalable proxy scanner and tester written in Go. It is designed to ingest thousands of proxy links (VLESS, VMess, Trojan, Reality, etc.), filter out dead nodes efficiently using "cheap" network checks, and rigorously test survivors using a real Sing-box core.

It uses a "Funnel Architecture" to minimize resource usage, allowing it to scan 100,000+ proxies without crashing your system.

🚀 Architecture

The system processes proxies through a multi-stage pipeline:

graph LR
    A[Source File/URL] --> B(Parser)
    B --> C{Dedup}
    C -- New --> D{Cheap Filter}
    C -- Duplicate --> X[Discard]
    D -- TCP/TLS OK --> E(Sing-box Core)
    D -- Fail --> X
    E -- Latency OK --> F(GeoIP Enricher)
    E -- Fail --> X
    F --> G[JSONL Sink]

🛠️ Prerequisites

1. Go 1.21+ installed.
2. Sing-box Binary: The engine that powers the tests.
3. GeoLite2 Database (Optional): For country detection.

📦 Installation

1. Clone & Dependencies

git clone https://github.com/sajadMRjl/find-me-internet.git
cd find-me-internet
go mod tidy

2. Install Sing-box

Download the latest release for your OS from Sing-box Releases.

• Extract the binary.
• Place it in the ./bin/ folder (or anywhere you like).
• Linux/macOS: Ensure it is executable: chmod +x ./bin/sing-box

3. Setup GeoIP (Optional)

• Register for a free MaxMind account.
• Download the GeoLite2-Country.mmdb.
• Place it in ./data/.

⚙️ Configuration

Create a .env file in the root directory:

# --- General ---
LOG_LEVEL=INFO           # Options: DEBUG, INFO, WARN, ERROR
MAX_WORKERS=50           # Concurrency limit for Sing-box instances

# --- Timeouts ---
TCP_TIMEOUT=2s           # Max time for "Cheap" TCP connect
TEST_TIMEOUT=10s         # Max time for "Expensive" HTTP test
TEST_URL=http://cp.cloudflare.com  # The target to fetch

# --- Paths ---
SING_BOX_PATH=./bin/sing-box
INPUT_PATH=./data/proxies.txt
OUTPUT_PATH=./data/valid_proxies.jsonl
GEOIP_PATH=./data/GeoLite2-Country.mmdb

🏃 Usage

1. Prepare Input: Add your raw proxy links (one per line) to data/proxies.txt.
2. Run the Scanner:

go run cmd/main.go

3. View Results: Valid proxies are streamed to data/valid_proxies.jsonl.

tail -f data/valid_proxies.jsonl

Output Example

{"link":"vless://uuid@1.2.3.4:443...","type":"vless","address":"1.2.3.4","port":443,"latency_ms":145,"country":"DE"}
{"link":"vmess://...","type":"vmess","address":"5.6.7.8","port":80,"latency_ms":210,"country":"US"}
