Citro Labs launches ego lite, a browser built for AI agents

3 Key Points

  1. What happened

    Citro Labs released ego lite, a free Chromium-based browser for macOS and Windows. It connects agents such as Claude Code and Codex, and it uses task-level workspaces called Spaces to separate the agent's pages from the user's tabs.

  2. Why it matters

    Users share one logged-in browser session while the agent works in its own Space, so people can keep browsing and hand off tasks without setting up a separate environment or letting the agent take over their open pages.

Context & Analysis

Citro Labs frames ego lite as an answer to a gap left by faster code generation: the manual work of opening a browser, logging in to staging, searching, and moving between screens. While coding agents can write code, many follow-up tasks live behind a GUI and a login, so the company wanted a browser where the user can hand off the next step rather than build a separate agent environment. Its design separates workspace and control rights by task through Spaces, and initial setup can migrate browser data from Chrome and similar browsers.

The Snapshot feature reflects a second design choice: rather than feeding the agent raw HTML, ego lite returns structured text describing roles and names of buttons, links, and inputs, while reserving DOM extraction and screenshots for cases like collecting table rows or checking a chart's appearance. Execution is split as well, with known steps batched into a single script and observation repeated at branch points. The company says its own team first used it for checking freshly implemented screens, and it is aiming the browser at non-developers who can describe what they want verified in natural language.

FAQ
Which agents can I connect to ego lite?
The company says you can connect agents you already use, naming Claude Code and Codex as examples.
How does ego lite keep the agent from disturbing my browsing?
Agents work in per-task Spaces that are separate from your tabs and profile, while you share the same login state and can step in when extra authentication is needed.
What happens to the pages the agent reads?
Browser data is managed on the device, but page content the agent reads may be passed to the model in use, so the company advises following each team's data-handling policy.
