@yukiakai/proxy-probe

A proxy testing CLI for single and batch proxy evaluation.

Why?

Testing proxies at scale is messy:

• large files → crash or memory spike
• inconsistent formats
• slow sequential testing

@yukiakai/proxy-probe focuses on:

• streaming processing (low memory)
• concurrent testing
• clean output separation

Features

• Test single proxy or proxy list from file
• High-performance concurrent pool testing
• Retry support for unstable proxies
• Streaming + chunk processing (safe for large files)
• Supports HTTP / HTTPS / SOCKS4 / SOCKS5

Installation

npm install -g @yukiakai/proxy-probe

Usage

Test a single proxy

proxy-probe url http://127.0.0.1:8080

Test proxies from file

proxy-probe file proxies.txt --out-dir ./output

Options

--out-dir <path>        Output directory (file mode)

Input format

Each line:

http://user:pass@host:port
socks5://host:port

Output

File mode

Generated files:

success.txt    # working proxies
error.txt      # failed (timeout, refused, etc.)
invalid.txt    # malformed input

Example

proxy-probe file proxies.txt --out-dir ./out

Notes

• Large files are processed in chunks → no memory overflow
• Order is not guaranteed due to concurrency
• Designed for testing availability, not anonymity level
