Browser Profiles
Give any browser tab its own login — a profile with separate cookies, storage, and history — so you can be signed in to the same site as two different accounts at once, and an agent driving a tab acts as the account you chose.

Why You Need This
How this feature boosts your daily productivity
A normal browser gives you one cookie jar, so being signed in twice to the same site means an incognito window, a second browser, or logging out of the tab you were just using. Inside 1DevTool that pinch was tighter, because you and the agent shared one session — testing a signed-in flow kept clearing the login you needed a moment later. Profiles fix it at the source: each is a self-contained identity, any tab can point at any profile, and a tab handed to browser automation inherits the exact profile you picked. New tabs follow a default you set, or stay on one Shared session until you decide to split them. Each profile even tells sites whether to Look like Chrome so sign-ins and checkouts behave, and keeps its own history you can browse or wipe.
How It Works
Get started in 4 simple steps
Make a profile in Settings → Browser
Open Settings → Browser → Profiles and press Add profile. Each one is a self-contained login with its own cookies, storage and history, listed beside the built-in Shared session.
Point a tab at it from the toolbar
Every tab has a profile picker in its toolbar. Choose Open this tab as and the tab reloads on that profile's cookie jar, while the tab beside it keeps its own.
Set a default, or stay shared
Pick a default profile for new tabs, or leave everything on the one Shared session — a single cookie jar for the whole app — until you want to split logins.
Choose how sites see it
Per profile, choose Look like Chrome so sign-ins and checkouts behave normally, or 1DevTool's native identity for the rare page that needs it. Browse or wipe each profile's history in the same place.

Why It Matters
The productivity impact of having browser preview built into your workspace
Two Accounts, No Incognito
Being signed in twice to one site stops meaning a second browser or a private window. A second tab on a second profile is the whole trick.
The Agent Acts As Who You Chose
A tab driven by browser automation uses the same session you see, so "act as this account" becomes the profile you picked instead of whatever login happened to be active.
Logins That Do Not Bleed
Work, Staging and a throwaway test account keep separate cookie jars, so testing a signed-out flow never clears the signed-in one you needed next.
Sign-Ins That Just Work
Look like Chrome keeps checkouts and OAuth pages behaving normally, so a separate identity does not cost you the pages that care which browser you are.
