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.
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.
Go to Proxy CheckerA 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.
Preview the toolPick the checks you need — each one is a separate, real request, not an estimate.
Country, region and city the exit node actually resolves to.
The address a remote server really sees behind the proxy.
Whether a target URL is reachable through the proxy at all.
Support for encrypted tunnels via the CONNECT method.
Detects proxies quietly rewriting the traffic passing through them.
HTTP, HTTPS or SOCKS — verified rather than assumed.
Which identifying headers leak your original address.
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.
