ego(lite) gives AI agents a separate browser Space, but isolation remains a question

The Chromium-based browser aims to let agents use existing logins without disrupting a person’s tabs, but mixed review results suggest careful setup and supervision are still needed.

For people trying to run AI agents inside a browser without destroying their own workflow, ego(lite) is pitching a very specific answer: a Chromium-based browser that keeps a person’s normal tabs, sessions and extensions intact while agents work in a separate Space. The user behind the original post says that, after struggling with Claude Code’s browser control and with other agent setups that either discarded logins or took over the whole window, ego(lite) felt unusually close to a standard browser with an extra workstation for automation. The official site says the browser can import Chrome data, reuse signed-in sessions and store data locally, although those are the developer’s claims rather than independent proof of security or reliability.

That first impression matters because browser automation often fails at the most ordinary point of friction: authentication. According to the official quick-start guide, ego(lite) can import bookmarks, passwords, cookies and extensions during onboarding, and macOS may ask for the keychain password at that stage. The guide also says the browser can scan for installed agents and place an ego-browser skill into the relevant skill directory automatically. In the account posted on V2EX, that happened with no manual configuration, which reduced the setup burden that usually comes with browser tooling.

The workflow is designed around separation rather than replacement. The documentation says agents use a dedicated Space, where their tabs can be watched, taken over or stopped, while the user continues browsing elsewhere. The skills documentation describes ego-browser as a bridge that lets an agent work with the browser’s logged-in state, and positions it against both browser extensions and command-line browser tools. The same idea appears in the GitHub project page, which presents the product as a way for agents to use a person’s logged-in browser without interrupting everyday use.

In practical terms, that separation is the product’s main promise. The V2EX writer says the browser no longer hijacks the active tab or scrambles the whole window, which is a common complaint with direct browser control. When the agent needs attention, the user can step in to handle a login prompt or verification challenge, then hand control back. That is also consistent with the official Claude Code guide, which recommends switching to Code mode, enabling bypass permissions and taking over the browser for verification rather than trying to enter sensitive details through the prompt.

There are, however, caveats that matter for anyone considering it seriously. The official materials should be read as vendor documentation, not neutral testing, and the GitHub project page does not prove the entire browser is open source. An independent review published in September 2026 reported mixed results, including a case where the wrong browser profile was selected and other runs that were slower or more awkward than expected. It also warned that separate Spaces may not fully isolate cookies, suggesting that a dedicated profile may still be the safer choice for agent work. Taken together, the material points to a promising but still maturing approach: one that reduces the worst browser-automation annoyances, but does not eliminate the need for careful setup and manual supervision.
