ego (lite) is a free browser purpose-built for AI agents that need to operate real websites. It is based on Chromium and behaves like Chrome for everyday browsing, but it adds an agent layer: once you install the ego-browser skill, agents such as Claude Code, Codex, Cursor, Kiro and others can drive the browser directly, with no SDK and no remote debugging setup. You simply tell your agent what you want and it executes the task.
Its defining feature is login reuse. ego (lite) imports your entire Chrome setup in one click, so every site you are already signed into stays signed in and the agent inherits the same authenticated state. This makes it practical for automating Gmail, Notion, LinkedIn, SaaS dashboards and internal tools without maintaining selectors or login scripts. The agent works inside an isolated Space rather than your tabs, so it does not steal focus or take over your mouse.
Under the hood, ego (lite) builds semantic snapshots inside its own Chromium engine instead of injecting a script like many stock-Chrome tools. Snapshots arrive faster, actions run more reliably, and they reach into cross-origin iframes, shadow DOM and embedded widgets such as Stripe, Salesforce and Intercom. In ego's own real-world benchmark, ego-browser completed complex tasks roughly 47–63% faster than alternatives with a 93.5% success rate and a lower average cost per task. Browser data such as bookmarks, passwords and history stays on your computer. It is available for Mac and marketed as always free with no account required.
