Free Bulk Proxy Checker

Introduction

This tool provides a fast and efficient way to check the status, type, speed, and anonymity level of a list of proxies in bulk. It supports common proxy protocols: HTTP, SOCKS4, and SOCKS5.

Paste your proxy list (in IP:Port format) into the text area and click Check Proxies. Results appear below, categorized for easy filtering. Use the Copy [Filter] button (next to the filter tabs) anytime to grab the currently visible results.

How It Works

The checker operates in two main parts:

1. Frontend (Your Browser): Parses input, manages the checking queue (up to 10 concurrently), sends requests to the backend, displays results, and handles UI interactions like filtering and copying.
2. Backend (This PHP Script): Receives a request for a specific proxy (/?proxy=...), uses PHP cURL to test connections via HTTP, SOCKS5, SOCKS4 to its own /?myip endpoint. This endpoint returns connection details as seen through the proxy. The backend analyzes this response to determine status, type, speed, and anonymity, sending the results back as JSON.

Features & Uses

• Bulk Checking: Test large lists quickly.
• Multiple Protocols: Auto-detects HTTP, SOCKS4, SOCKS5.
• Speed & Anonymity: Measures connection time and classifies anonymity (Elite, Anonymous, Transparent).
• Concurrency: Checks up to 10 proxies simultaneously.
• Filtering & Retry: Easily view results by status and re-check errors.
• Copy Results: Copy the currently visible (filtered) proxy list and their status at any time.
• Responsive: Works on desktop and mobile.

Common Uses:

Verify proxy lists, find working proxies for tasks, monitor proxy pools, select proxies by criteria.

FAQ

Anonymity Levels?

• Elite: Hides proxy usage and your IP.
• Anonymous: Hides your IP but signals proxy usage (e.g., VIA header).
• Transparent: Reveals proxy usage and your IP (e.g., X-Forwarded-For header).
• Unknown: Could not be determined (connection fail, bad response).

Why 'Dead' or 'Error'?

• Dead: No successful connection on any protocol within timeout.
• Error: Network issue, timeout during check, proxy access denied, invalid response, or script error. Tooltip may give details.

Speed Accuracy?

The time reflects connection to the internal endpoint via the proxy. Good for relative comparison, affected by server/proxy load and network path.

Is it Safe?

The checker connects *through* your proxies to its *own* endpoint. It doesn't store your list long-term. Use proxies from trusted sources responsibly.
