Why ego(lite) is better than Kimi Chrome extension

Both keep execution local, but they put the agent in different places. ego(lite) gives any compatible coding agent a full Chromium surface for search, research, extraction, forms, testing, and other web work, while Spaces keep its activity separate and parallel.

The agent never fights you for your browser again

Because every task gets its own Space (a separate workspace inside the same browser), agents can run in parallel without ever touching the tabs you're using, and everything stays visible while it works.WebBridge works the opposite way: the agent operates inside the same Chrome or Edge window you already have open (the very window you're trying to use), so you and the agent end up sharing one browser.

Faster on both tasks, measured against Kimi WebBridge

WebBridge's agent (even running Kimi's own K3 model at high reasoning effort) works through Chrome DevTools Protocol tool calls: one click, one read, one keystroke at a time. On two real tasks, ranking OpenAI's X posts took WebBridge 4 minutes 57 seconds, and the Expedia flight-booking task took 15 minutes 26 seconds.ego(lite) reads the page as a compressed Snapshot and batches several actions into a few lines of JavaScript per turn. On the two tasks shown here, it completed both runs faster with fewer model turns.

Time to finish the same tasks, shorter is better

Task 1: Rank OpenAI's X posts from the last 7 days

  1. ego(lite)
    87 s
  2. Kimi WebBridge (K3 high)
    297 s

Task 2: Expedia: search, filter, and fill a flight booking

  1. ego(lite)
    166 s
  2. Kimi WebBridge (K3 high)
    926 s

Both keep things local and open: ego(lite) adds parallel tasks

Credit where it's due: WebBridge is free, keeps everything running locally, and works with agents beyond Kimi's own, including Claude Code, Cursor, and Codex. But it's still one browser window shared between you and the agent, one task at a time.ego(lite) keeps that same local, open approach and adds parallel Spaces on top, so several tasks can run at once, using whatever agent you already have.

One app instead of a three-piece bridge that can fall out of sync

WebBridge really is a bridge: Chrome, the WebBridge extension, and the Kimi desktop app's local service all have to be running and correctly paired before an agent can control a page. Moonshot's own FAQ documents this as a common problem: the extension shows as disconnected if the local service isn't running yet, and actions like snapshot or click can fail if another extension conflicts with WebBridge.ego(lite) collapses all of that into a single install, because ego(lite) is the browser. Import your Chrome profile, run /ego-browser, and there's no separate service to pair and nothing else that can conflict with it.

Make it a seamless transition

If WebBridge already connects your CLI agent to a browser, you know the workflow. ego(lite) keeps it and removes the sharing and the pairing.

1

Download ego(lite)

Download ego(lite) and import your Chrome profile in one click. The logged-in sessions WebBridge borrows from your window come along as real profile state.

2

Run your first task with /ego-browser

Run /ego-browser inside Claude Code, Codex, Cursor, or the CLI agent you were pointing at WebBridge. No extension, no desktop-app pairing.

Paste into your agent

/ego-browser Open ego.app and join the waitlist

3

Watch it work

Re-run your last WebBridge task and keep using your own browser while it executes: the agent works in its Space, you work in yours.

Keep Kimi Explorer if you like its summarize-and-ask reading workflow; ego(lite) replaces the agent-drives-the-browser layer, not the page assistant.

When to use each tool

Choose ego(lite) when

  • You want agents in their own Spaces, running tasks in parallel, while the tabs you're using stay yours.
  • You want one install instead of three pieces: no extension, no desktop-app pairing to fall out of sync. Import your profile and run /ego-browser.
  • You care about per-task speed: compressed Snapshots plus batched multi-action JavaScript beat WebBridge's step-by-step CDP tool calls: 87s vs 4:57 on the same X-research task, 166s vs 15:26 on the same Expedia flight task.
  • Your logins matter and should be real profile state, imported once, not borrowed from whatever window is open.

Choose Kimi Chrome extension when

  • You're already in the Kimi ecosystem (Kimi Code CLI and the desktop app), and WebBridge is the native fit.
  • You specifically want agents driving the exact Chrome or Edge you already have open, unchanged, with its live sessions.
  • You want to stay in your current browser entirely: no new browser to install or switch to, just an extension in the one you use.

FAQ

What is Kimi Chrome extension?

Moonshot AI ships two Chrome extensions under the Kimi name. Kimi Explorer is a reading assistant: summarize the page you're on, ask questions about it, get writing help without switching tabs. Kimi WebBridge, released in May 2026, is the agent one; it pairs with the Kimi desktop app to let CLI agents (Kimi Code CLI, Claude Code, Cursor, Codex) operate your existing Chrome or Edge window locally, with cookies and logins intact and page content staying on your device. WebBridge's local-first, agent-agnostic design is genuinely good, and philosophically the closest thing to ego(lite) in the extension world.

What's the difference between Kimi Explorer and Kimi WebBridge?

Kimi Explorer is a page assistant: summarize the article you're reading, ask questions about it, draft text. Kimi WebBridge is agent infrastructure: paired with the Kimi desktop app, it lets CLI agents operate your Chrome or Edge window locally. If you're comparing against ego(lite), WebBridge is the relevant one.

Is ego(lite) a good alternative to Kimi WebBridge?

Yes, if you want the same local, agent-agnostic approach without sharing your window or the three-piece pairing. ego(lite) runs agents in their own Spaces in parallel, imports your Chrome profile so logins persist, and needs one app instead of an extension-plus-desktop-app pair. WebBridge wins if you specifically want agents driving the exact browser you already have installed, unchanged.

Is Kimi WebBridge reliable once it's set up?

Moonshot's own help center documents two common failure modes worth knowing before you rely on it: the extension shows disconnected when the local Kimi service isn't running yet, and actions like snapshot or click can fail when another installed extension (scraping tools, AI assistants) conflicts with WebBridge, which the FAQ suggests troubleshooting by disabling other extensions one at a time. ego(lite) has no local service to keep running and no extension it can conflict with, since it is the browser.

Does ego(lite) work with Kimi Code CLI?

Any CLI agent that writes code can plug in through the open-source, MIT-licensed ego-browser shell. That includes custom agents. Claude Code, Codex, Cursor, Gemini CLI, and Opencode are the documented entry points; a code-writing CLI agent like Kimi's connects the same way.

Can I keep browsing while the agent works?

In ego(lite), yes: agents run tasks in their own Spaces and never take the tabs you're using, and you can watch or take over any Space. With WebBridge, the agent operates the window you have open, so an active task and active browsing compete for the same session.

Is ego(lite) free?

Yes: free, no subscription, data stored locally, and the ego-browser shell is MIT-licensed open source. You bring your own agent and pay only whatever that agent already costs you.

How can I integrate Kimi Code without an API or CLI?

A desktop assistant or browser extension can provide a guided UI path, while a coding CLI exposes scripts and automation hooks. If you do not have an API or CLI, keep the workflow human-triggered: define the task in the product UI, review the browser actions, and export the result. ego(lite) is explicitly agent-driven through /ego-browser, so it still requires a compatible code-writing agent rather than pretending a missing integration exists.

Why might Kimi work glitch or consume quota mid-task, and how can I reduce it?

Long browser tasks can spend quota on repeated snapshots, retries, tool calls, and recovery after a disconnected bridge. Reduce surprises by splitting work into bounded steps, setting a time and token budget, saving intermediate results, and requiring pass, fail, or blocked status with evidence. ego(lite)'s local Spaces and batched actions can reduce browser round trips, but your model still has its own limits and costs; inspect the run instead of assuming a failed task completed.

Give your agent a real browser

Free, runs on your computer, imports your Chrome profile in one click. Works with Claude Code, Codex, Cursor, and any CLI agent that writes code.
