ego-lite

The fastest browser for AI agents to run web automation

English · 简体中文 · 日本語 · 한국어 · Português · Español · Français · Italiano · Русский

ego (lite) is a browser where you and your AI agents work in parallel. Your agents run their browser tasks in their own Spaces, isolated workspaces inside the same browser, while you keep browsing in yours, so no agent ever takes the browser away from you. And the automation itself finishes faster, on fewer tokens.

Existing tools like browser-use and agent-browser are a bridge to the browser, not a browser of their own: they need a separate one to drive, your browser data rarely carries over intact, the connection is unstable, and you and the agent end up fighting over control of the browser. ego lite is one browser designed from the start for the two of you to share. No extra setup, and the agent can always reach your real logins and tabs through ego-browser.

Quick Start

ego lite runs on macOS today, a Windows closed beta is coming soon, and Linux is on the roadmap.

1. Install

Pick whichever fits your flow.

1.1 Download the macOS app

Click to download, then open it to install. Either way, ego lite adds the ego-browser skill to every agent's skills directory on your machine.

1.2 Add the skill with npx

Install just the ego-browser skill:

npx skills add citrolabs/ego-lite

The first time your agent runs a browser task, it walks you through installing the ego lite app.

1.3 Let your agent set it up

Paste this into your agent:

Set up ego lite for me: https://github.com/citrolabs/ego-lite

Read `skills/ego-browser/references/install.md` and follow the steps to install ego lite.

On first launch, ego lite asks one question, whether to migrate your Chrome data. Say yes and your agent inherits your existing logins, cookies, extensions, and bookmarks.

2. Try your first task

In your agent CLI, type /ego-browser followed by a space, then describe what you want in plain language:

ego-browser follow @ego_agent on x.com for me

The agent picks up the ego-browser skill, opens the page in its own Space, reads a Snapshot (the page turned into structured text), acts on the page, and reports back, all while your own tabs stay untouched.

Your browsing data, cookies, and everything else the browser holds stay on your device. ego lite keeps its data collection deliberately narrow: simple product signals, like whether you've set ego lite as your default browser.

Highlights of ego lite

Feature	What it does
Code-based, not CLI-based: faster runs on fewer tokens for complex tasks	The capabilities ego lite exposes to the agent are wrapped as JavaScript functions the agent calls directly. The agent gets to do what it does best: write code, composing a multi-step task into a single output instead of getting stuck in a "call two commands, look at the result, call two more commands" loop. Compared to the conventional CLI approach, complex workflows finish far faster, with higher task success rates, far fewer tool calls per task, and a much lower cost per task.
A dedicated Space for every agent	ego lite gives each agent its own fully isolated Space. You browse up front, your agent works in the background, and they don't get in each other's way. You can see which Space has an agent running at any moment, and take it over or stop it whenever you want.
Your agents multitask in Spaces, parallel workspaces inside the same browser	Each Space gets its own AI agent or its own task, all running at the same time. Claude Code enriching 10 leads in 10 parallel Spaces. Codex scraping 5 competitor sites in 5 more. They don't collide or steal your tabs. Your mouse stays where you left it.
The strongest page Snapshot on the market	Thanks to customization inside the browser engine, ego lite produces the highest-quality page snapshots, the view text-only models rely on to "see" and act on a webpage. It reliably handles tough cases like deeply nested iframes, exactly where other approaches consistently break down.
Any agent can drive it through ego-browser	ego-browser is the connection layer between any agent CLI (Claude Code, Codex, Cursor, or a custom one) and ego lite. It exposes the browser as a set of in-page JavaScript tools: snapshot, fill, click, wait, navigate, capture. The agent writes a JavaScript snippet calling those tools, and ego-browser runs it on the page in one pass.
Experience accumulation that makes your agent faster the more you use it (coming soon)	Most of an agent's time on browser tasks goes to trial and error. ego lite's official Skill distills every successful action into reusable tools and workflows, so similar tasks down the line run up to 5x faster.

ego lite vs existing products

Most tools can automate a browser. The real questions are what browser the agent gets, whether you can keep working at the same time, and whether the tool is built for the agent you already use or a built-in one.
