🧠What LoginDeck is and how it works

LoginDeck is an antidetect browser: one app that runs many separate browsers on your computer, so several accounts on the same website never look like they share a machine. It also automates those browsers, so work you'd otherwise repeat by hand runs on its own.

🧩 Profiles: one browser per account#

Everything in LoginDeck starts with a profile. A profile is a whole browser of its own:

• its own cookies, storage and cache, so a login in one profile is invisible to the others;
• its own fingerprint — the operating system, graphics card, screen size, fonts, language and timezone a site reads;
• its own proxy, so it browses from an address you choose;
• its own extensions, and its own saved logins and 2FA codes if you add them.

Profiles appear one per row on the All profiles page. Press Run on a row and a browser window opens for that profile alone. See Create a browser profile.

🧬 Fingerprints: a machine that adds up#

Keeping cookies apart is the easy half. The harder half is looking like one real computer.

LoginDeck generates each profile's machine from a single seed, then reads every trait off that one choice, so the values agree with each other: a Windows profile reports Windows fonts and a graphics card a Windows PC would have. Randomising each value on its own would produce combinations no real computer has, which is a louder signal than not hiding anything.

You don't have to pick any of it. Create a profile and the fingerprint is built for you. See What a browser fingerprint is.

🌐 Proxies: where each profile browses from#

A proxy is the address a profile appears to browse from. In LoginDeck you can:

• save proxies in a library and point profiles at them,
• type a one-off proxy for a single profile,
• or use your own Android phone as a mobile exit.

When a profile's proxy is checked, its timezone and language follow the proxy's exit country, because a clock that disagrees with the address is one of the easiest mismatches for a site to spot. See Which proxy should I use?

🖥️ Browser engines#

LoginDeck doesn't drive your everyday Chrome. It ships its own browsers:

• Chromium — the default engine, with full support for automation, the Paste-as-human tool and cookie sync. Several Chrome versions are available, and a profile runs on the version picked in its editor.
• Firefox — a second engine, built on Camoufox. Automation and cloud cookie sync are Chromium-only for now.

The engines download separately from the app, once, and every profile that picks a version shares it. See Chrome or Firefox, and which browser version.

⚡ Flows: automation without code#

A Flow is a job you draw instead of writing. Place steps, wire them from start to end, and run the Flow on one profile or hundreds. A run drives the profile's real browser, with the same fingerprint, proxy and cookies as pressing Run yourself.

• Steps find things on the page by what they are — their text, their label — rather than by a fragile selector, so a Flow survives a site redesign.
• You can describe the job in words and let LoginDeck's AI build the Flow for you.
• Flows can run on a schedule, and there are ready-made templates to start from.

See What Flows are and what they can do.

🔄 Sync: your deck on your other computers#

Your profiles live on your disk. If you sign in on a second computer, LoginDeck brings the deck with you: profiles, saved proxies (including their passwords), folders, tags and Flows sync on every plan. On paid plans the logins travel too, so a profile opens already signed in on the other machine.

Everything is encrypted on your computer before it's uploaded. See What syncs between your computers and How your data is protected.

👤 Who it's for#

LoginDeck is built for people who run more than one account on the same platforms:

• ad buyers with several ad accounts, or one per client;
• agencies and freelancers who need each client's work kept apart, with staff scoped to only their folders;
• sellers on marketplaces with more than one storefront;
• anyone managing a set of social accounts who wants the routine parts automated.

ℹ️ Good to know#

• Windows 10/11 (64-bit) today. A macOS build is on the way; the site still says macOS is coming soon.
• The free plan is real: 10 profiles on 2 computers, no card, no expiry. See The free plan.
• Nothing runs in our cloud. The browsers run on your computer, which is why there's no per-hour cost and no queue.
• No antidetect browser makes you invisible. For an honest list of what can and can't be changed, read What no antidetect browser can change.
