Disposable browser

A browser you throw away.

A real browser, spawned fresh, destroyed on close. Legba runs a headful Chromium on a fresh residential IP. You do the work. Then the whole browser burns. Nothing left behind.

Definition

What is a disposable browser?

A disposable browser is a real browser that exists for one job and then is destroyed. You spawn a fresh session, do your work, and close it. When it closes, the whole browser is gone. Cookies, storage, tokens, and fingerprint go with it.

It is not a private window on your own machine. The browser runs off your device, on a fresh residential IP, with a new fingerprint each time. Nothing carries in from your last session. Nothing carries out to your next one. Whatever the page does stays inside the session.

Legba is a disposable browser engine. It spawns a headful Chromium, lets a human or an agent drive it, and burns the session on close. There is no trail back to your device, your stack, or your identity.

How it works

Three calls. One throwaway browser.

Spawn the browser. Do the work. Burn it on close. The lifecycle is the same whether a human drives it or an agent does. Nothing persists unless you say so.

[ session lifecycle ]

  1. Spawn the browser.

    A real headful Chromium boots on a fresh residential IP. New fingerprint. No cookies carried in.

  2. Do the work.

    Open the link, log in, run the task. The page loads off your device, not on it.

  3. Burn it on close.

    Close the session and the browser is destroyed. Cookies, storage, fingerprint: gone.

Compared

Disposable browser vs incognito vs VPN.

Incognito hides your history from your own machine. A VPN changes your IP. A disposable browser moves the whole browser off your device, then destroys it.

Who it is for

One browser. Thrown away each time.

Anyone who needs a clean session that leaves no trail.

PRIVACY

Browse without leaving a trail.

Open accounts, read, and research without your IP, fingerprint, or history following you. The session is fresh and gone on close.

OSINT

Look without being recognized.

Visit a target site from a clean session, not your office IP. Each spawn is a new identity, so the trail does not lead back.

Connect a wallet off your machine.

Open a dapp or sign a transaction in a throwaway browser. Drainer scripts and malicious pages never touch your device.
