Isolated Agent Spaces and Shared Browser State
Ego Lite runs on macOS and integrates with CLI agents such as Claude Code, Codex, and Cursor. During initial setup, the browser offers to migrate Chrome data, transferring existing logins, cookies, extensions, and bookmarks. The browser exposes an ego-browser skill directly to your machine's local skills directory, allowing agents to operate within background Spaces without stealing mouse focus or disturbing main browsing tabs.
Direct JavaScript Execution vs CLI Command Loops
Unlike traditional CLI automation frameworks that rely on iterative tool-call cycles, Ego Lite provides JavaScript tools—such as snapshot, fill, click, wait, navigate, and capture. Agents compose multi-step browser interactions into a single JavaScript code snippet executed on the page in one pass. Benchmark tests against Vercel's agent-browser across four complex web automation tasks demonstrated up to 2.5x faster completion speeds alongside significant token savings.
