ego lite: a browser built for you and your AI agents to work side by side
Citro Labs ships a desktop browser that gives each agent its own isolated Space — no tab fights, no login friction. Tasks run 2.5× faster than agent-browser on complex workflows, and the browser inherits your Chrome data from day one.
The 60-second version
ego lite is a macOS browser rethought for human-AI collaboration — each agent gets an isolated Space, tasks run via JavaScript functions instead of CLI loops, and it inherits your Chrome session so logins don't need redoing.
Key points
- Each agent runs in its own fully isolated Space inside the same browser — multiple agents can work in parallel without interfering with the user's tabs.
- Browser capabilities are exposed as JavaScript functions the agent calls directly, not CLI commands — complex workflows are up to 2.5× faster than agent-browser with fewer tokens.
- Inherits Chrome data (logins, cookies, extensions, bookmarks) on first launch — no login friction for automated tasks.
- Any agent CLI (Claude Code, Codex, Cursor) can drive it through the 'ego-browser' connection layer. Free, MIT-licensed on GitHub.
Verdict. ego lite solves a real pain point for anyone running agentic workflows — parallel workspaces and token-efficient JS function calls are genuinely novel. The macOS-only limitation and early-stage benchmark claims are worth watching, but the architecture is the most thoughtful browser-for-agents design so far.
The problemBrowser automation hits a wall
When an AI agent needs to do something in a browser — fill a form, scrape a page, manage a SaaS account — the current options all involve compromise. Browser automation frameworks like Browser-Use and agent-browser are libraries the agent calls, but they ship no browser of their own, so the agent needs a separate instance to drive and your logins rarely carry cleanly. AI browsers like ChatGPT Atlas and Perplexity Comet ship a built-in agent, but only that one agent can drive — you can't bring your own Claude Code, Codex, or Cursor.
Either way, you and the agent end up fighting for the same tabs, or the agent runs headless without your session state.
The solutionOne browser, two lanes
ego lite, from Citro Labs, is a desktop browser designed from the ground up for shared human-agent browsing. It gives each agent a dedicated, isolated Space — a parallel workspace inside the same browser that doesn't touch your tabs. You browse up front; agents work in the background. Multiple agents can run in their own Spaces simultaneously.
ArchitectureHow it works
ego lite has three design pillars:
- Isolated Spaces — Each agent runs in its own fully independent workspace. The user can see which Space has an active agent at any time, take it over, or stop it. Multiple agents can work in parallel without collisions.
- JavaScript functions, not CLI commands — Instead of emitting separate CLI tool calls (snapshot, think, click, wait, snapshot again), ego lite exposes browser capabilities as JavaScript functions the agent calls directly. The agent writes one snippet that composes the whole task into a single output — up to 2.5× faster and far fewer tokens than the CLI approach.
- Chrome data inheritance — On first launch, ego lite asks whether to migrate your Chrome data. Say yes, and the agent inherits your existing logins, cookies, extensions, and bookmarks. No re-authentication for every automated task.
Benchmarks2.5× faster than agent-browser
Citro Labs benchmarked ego lite against Vercel's agent-browser on four complex browser automation tasks. ego lite finished each task up to 2.5× faster with substantially fewer tokens. The harder the task, the wider the gap.
ComparisonHow it stacks up
ego lite claims several capabilities that no single existing tool combines: multitasking in parallel, reusable skills via the skills.sh ecosystem, Chrome data inheritance, compressed semantic input, and the ability for any external agent CLI to control it — all while running as a full daily-use browser that stores data locally.
AvailabilityFree, open-source, macOS first
The ego lite browser app is a free download. The skill connector and open-source components are MIT-licensed. The GitHub repo already has over 1,600 stars. For teams and power users, the roadmap includes Windows and Linux builds, and a 'experience accumulation' feature that distills successful agent actions into reusable tools for up to 5× faster task completion over time.
