Online checkers by ATMLAB
ATMLAB Checkers is a set of professional online tools for analyzing network connections, proxy servers, and browser environments. All checkers are developed with a focus on accuracy, transparency of checks, and an engineering approach without marketing “magic”.
This section brings together specialized tools that allow you to quickly verify real connection parameters, detect anonymity, data substitution, or access restrictions.
Available checkers
Proxy Checker
Proxy Checker is the core ATMLAB tool for in-depth proxy server analysis. It allows you to determine the real outgoing IP, geolocation, anonymity level, HTTPS support, presence of MITM interference, and proxy type.
The checker is suitable for testing datacenter, residential, and mobile proxies, as well as identifying unstable or insecure proxy providers.
Upcoming tools
Browser Info Checker
A tool for analyzing data that the browser transmits to websites: User-Agent, browser fingerprint, WebRTC, Canvas, headers, and other parameters used for tracking and user identification.
The checker will help you understand how unique your browser is, which data can be used for tracking, and how proxies or VPNs affect browser identification.

ATMLAB approach
All ATMLAB checkers are built on a single principle: no simulation, no assumptions — only real data obtained from the network stack, browser, and connection.
We do not limit ourselves to simple “works / does not work” checks. The goal of ATMLAB tools is to show how exactly your connection looks through the eyes of a remote server.
