Kalkan has four engines: Kalkan Native (recommended), our own Chromium build that produces the fingerprint inside the browser's C++ code; Kalkan (Chrome patch), which drives the real Google Chrome on your computer with a patched driver; Kalkan Edge, the same layer on your installed Microsoft Edge; and Firefox. Build flows without code and run them across hundreds of profiles at once; your profiles, cookies and sessions stay on your own computer.
Go to URL, click, type, wait, scroll: line up the steps, give each profile its own data with variables, run them on the profiles you pick.
How it works SyncThe leader sits top-left in an equal grid. Mouse, clicks, scrolling and keys are mirrored to every profile in real time.
How it works 4 enginesPick the engine per profile: Kalkan Native with the fingerprint in its C++ code (recommended), your real Google Chrome, your Microsoft Edge, or Firefox.
How it works
In the visual flow builder you pick steps from a list and put them in order: go to URL, click, type, wait, scroll. Variables such as {{username}} give every profile its own data. The flow runs on the profiles you choose at the concurrency you set.

The first profile becomes the leader at the top-left of an equal grid; the others tile next to it. Every mouse move, click, scroll and keystroke in the leader is mirrored to every other profile in real time.
In Kalkan you choose each profile's engine: Kalkan Native (recommended), our own Chromium build that produces the fingerprint in the browser's C++ code; Kalkan (Chrome patch), which drives the real Google Chrome on your computer with a patched driver; Kalkan Edge, the same layer on your installed Microsoft Edge; and Firefox. All four share the same profiles, proxies and sync.
The typical antidetect browser approach and Kalkan's, side by side.
Kalkan
The table compares common approaches, not any specific product. No tool can guarantee going undetected on every site; Kalkan's job is to give you consistent, separate profiles that look like real devices.
Real screenshots: profiles, profile creation with a device preview, no-code RPA and sync.
Passing detection sites is the baseline. Kalkan's real job is identities that never resemble each other and never contradict themselves — across thousands of profiles.
Profiles are built from real device models, not random values. GPU, CPU, screen, language and time zone never contradict each other.
Import HTTP and SOCKS5 proxies in bulk; Kalkan tests each one, finds its country and sets the profile's time zone, language and location to match.
The cookie robot sends the profiles you pick around popular and the exit country's local sites, accepts cookie banners like a person and builds a realistic cookie / history footprint — so your accounts don't look freshly minted.
Kalkan's diagnostics test every profile with the checks sites use. All traffic goes through a local tunnel: no proxy headers, DNS in the exit's country, no UDP around the proxy.
Added in Kalkan 1.3.27 – 1.3.30. They arrive on their own when the app updates itself.
A profile's camera now behaves like the claimed model in every technical detail: its resolution and frame-rate list, brightness, exposure, focus and zoom ranges, facing direction and photo size all come from the model. Your own camera's values never reach the page.
New profiles' audio fingerprint matches the values real computers report and differs from profile to profile. The microphone's sample rate and channel count and the audio latency come from the profile's device, not from your hardware.
A profile's graphics card shows in WebGL and WebGPU the values that card really reports. Combinations no real card produces are no longer drawn, and cards in older profiles that Windows could never report are repaired on their own.
With UDP-capable SOCKS5 proxies, HTTP/3 is now verified with a real STUN measurement and turned off when UDP leaves from another IP. Dropped connections move to a new one on their own, and packet loss under heavy traffic is gone. WebRTC delay and port follow the real network of the exit.
The layer that carries a profile's identity is measured against stock Chrome in every release with a battery of current detection techniques. The browser's own error messages, stack depth and timing probes no longer give it away, and the identity is in place from the first line in every tab, frame and worker.
Your logins survive even when you close the browser with the X. In sync, clicks that navigate reach every window and a page always fills its window. The proxy bypass list works with one rule format on every engine: domain, subdomains, port, IP and CIDR.
Profiles are modelled on real OEM machines, not random values: GPU generation, CPU, screen and laptop/desktop traits all match.
Per-profile, persistent, natural-looking render noise. Same profile, same hash every time; two profiles never match.
HTTP / SOCKS5 per profile, with a kill-switch against WebRTC, UDP and DNS leaks. Time zone, language and location follow the IP.
Do it once, it happens in every profile. Windows tile evenly on your screen; clicks target the same element, not the same pixel.
Human-like mouse and typing; build flows and run them across hundreds of profiles at the concurrency you choose.
The system test checks your GPU, Chrome version and engine patches; if something is off it tells you how to fix it.
Sign up with your email; the 3-day trial starts at once.
Setup takes a minute; the system test checks your computer automatically.
Add a proxy, create a profile in one click and open it. Kalkan handles the rest.
Every plan includes all four engines (Kalkan Native, Kalkan, Kalkan Edge, Firefox) with full fingerprint protection. Plans differ by profile count, how many run at once, and RPA.

What is Kalkan? An overview of the Windows antidetect browser Kalkan: its engines, profile management, proxy pool, sync, no-code RPA, Turkish/English/Russian interface and plans.

Windows 10 (22H2) and Windows 11, 64-bit. The Kalkan engine needs Google Chrome installed and Kalkan Edge needs Microsoft Edge (Kalkan guides you if one is missing); the app downloads the Kalkan Native and Firefox engines itself.
There are four engines and you pick one per profile. Kalkan Native (recommended) is our own Chromium built with 150+ C++ patches in its source: GPU (WebGL and WebGPU), canvas, audio, screen, fonts and hardware values come from the browser's own code, not from scripts injected into the page, and agree everywhere, workers included. The app installs it in the background and keeps it up to date. Kalkan (Chrome patch) drives the real Google Chrome installed on your computer with a patched, Patchright-based driver. Kalkan Edge runs the same layer on your installed Microsoft Edge; the profile carries Edge's own identity and never signs itself in to your Windows account. Firefox is our Firefox-based engine; besides Windows, macOS and Linux profiles run on it.
No tool can honestly promise that. Kalkan keeps your profiles consistent and apart with real Chrome, real device models and a leak-free network identity. Proxy quality, your behaviour and the platform's rules shape the outcome too.
