4Price proxy checker Tool Overview
The 4Price proxy checker is a web-based utility that tests, verifies, and validates proxies in real time. It quickly shows whether a proxy is live, how fast it responds, and how reliable it appears across multiple proxy protocols.
So you can skip the tedious process of checking proxies one by one. Instead, you get live validation, speed analysis, and organized results in a single place.

Main Features of the 4Price proxy checker

Import Proxies from Multiple Sources
A solid proxy checker should make importing lists simple. 4Price handles that well, whether your proxies are stored in local files, GitHub repositories, or plain text.

File Upload: Supports .txt files and includes drag-and-drop upload functionality.
GitHub Integration: Allows direct import from popular proxy repositories using pre-configured sources.
Manual Input: Lets you paste proxies directly, with real-time counting and validation as you enter them.
Bulk Import: Supports importing proxies from multiple GitHub sources at the same time.

Advanced Testing Inside the proxy checker
This is the core of the tool. The proxy checker validates proxy usability across the major protocols and reports live progress while checks are still running.

Multi-Protocol Support: Validates HTTP, HTTPS, SOCKS4, and SOCKS5 proxies.
Concurrent Processing: Offers configurable simultaneous checks from 1-200 threads.
Timeout Control: Provides customizable connection timeout settings from 1-60 seconds.
Real-time Progress: Displays live progress tracking along with detailed statistics.

Results Management That Stays Practical
Once testing starts, reviewing the output stays straightforward. That matters when you are sorting through large proxy batches and need to separate usable entries from dead ones quickly.

Smart Filtering: Filter results by status such as working or failed, as well as by protocol type.
Export Options: Export validated proxies in TXT, JSON, or CSV formats.
Performance Metrics: Includes response time measurement and country detection.
Status Indicators: Uses clear visual indicators to show proxy health and performance.

User Interface and Live Dashboard
The interface is built for clarity and speed. On mobile, it remains easy to use; on desktop, it gives you enough visibility to track larger checking sessions comfortably.

Responsive Design: Optimized for both desktop and mobile devices.
Interactive Dashboard: Shows real-time statistics and credit balance tracking.
Progress Visualization: Includes animated progress bars and live status updates.
Clean Results Display: Presents results in an organized table with sorting and filtering options.

Technical Capabilities of the 4Price proxy checker

Supported Proxy Input Formats
The 4Price proxy checker accepts several widely used proxy formats. If your list comes from mixed vendors, shared repositories, or internal scripts, that flexibility saves prep time before validation begins.

Standard format: host:port
Protocol-specific: protocol://host:port
Authenticated: host:port:username:password
Alternative auth: username:password@host:port

Performance and Processing Features
This proxy checker is designed for bulk validation. Speed matters, but so does stable processing when you are running large lists and waiting for clean, usable output.

High-speed concurrent checking
Memory-efficient processing
Real-time result updates
Automatic duplicate detection
Error handling and recovery
