Browser Relay

Let AI agents use the same Chrome browser you use every day.

Browser Relay lets an AI agent join the Chrome browser you already use through an agent-native Skill + CLI. It does not launch a blank automation profile, keep pulling another browser window to the foreground, or make you log in again. You and the agent work in the same everyday browser — locally or across multiple machines.

Use it when the task lives in a browser that already has the right login, extensions, device trust, or network access: operate your desktop browser from an agent on your phone, reach an internal system through the already-authenticated browser on your work computer, or let one agent work across browsers on several machines.

Real Chrome, not a throwaway profile

Most browser automation spins up a fresh, empty browser profile. That is fine for testing, but useless for agents that need your authenticated web apps — SaaS dashboards, admin panels, internal tools, documents, private sessions — where a headless browser or a fresh profile simply is not logged in.

Browser Relay is that missing layer:

• Your actual Chrome session — cookies, localStorage, extensions, and login state, shared as-is.
• No pop-up automation browser — it never spawns a separate window or opens tabs behind your back; navigation reuses an attached tab.
• Local or remote — one agent can drive browsers on this machine or several other machines through an outbound relay connection, with no public browser port exposed.
• Agent-first — install the bundled Skill so Claude Code, Codex, Cursor, Windsurf, and other agents know when and how to use the inspectable CLI.
• Local-first boundary — the relay binds to 127.0.0.1 by default.

Provenance

Based on chengyixu/openclaw-browser-relay, with auto-attach behavior inspired by blakesabatinelli/openclaw-chrome-relay. Repackaged as a general-purpose local browser bridge for AI agents, without the OpenClaw-specific gateway, token auth, or platform bindings.

Architecture

Local
  AI Agent ──Skill + CLI──▶ Relay server (Node, 127.0.0.1)
                                        │ WebSocket
                                        ▼
                                 Chrome extension ──chrome.debugger / CDP──▶ your Chrome tabs

Remote (Remote Relay)
  AI Agent ──HTTPS──▶ public relay (relay.linso.ai) ◀──WSS── Chrome extension ──▶ your Chrome tabs

Local mode is the default: the agent talks to a relay server on 127.0.0.1, which forwards Chrome DevTools Protocol commands to the extension.

Remote mode exposes nothing. When you turn on Remote Relay, the extension connects out to a public relay service; a remote CLI reaches that same service, which routes each command down to your browser over the existing connection — no open ports, no local server on the network. Use the default hosted relay, or run your own on Cloudflare in one click (see below).
