Our first clean Relay run failed after the files were installed. The native host existed, the relay port was listening, and OpenClaw still returned zero attached tabs. That failure is the useful part of this guide: Browser Relay is a chain, not one green install message.
OpenClaw Browser Relay is the local connection path that lets OpenClaw inspect and operate an eligible Chrome tab through its extension, a loopback relay, and an authenticated Gateway or browser node. It isn't the OpenClaw-managed browser. It also doesn't grant access to every tab merely because Chrome is signed in.
What is OpenClaw Browser Relay, and when do you need it?
Browser Relay is for the moment when the task must happen in a Chrome profile that already contains an approved session. The extension uses Chrome's debugger permission on eligible tabs, then exposes those tabs through OpenClaw's local browser-control service. The browser still decides which pages the extension can touch.
The distinction matters. OpenClaw browser control also includes a managed profile and other CDP routes. Relay is the extension-specific route into an approved Chrome tab. Pick it only when that existing browser state is part of the job.
Which OpenClaw browser route fits the task?
Start with the state the task needs, not the most familiar command. The table separates control object from operating burden.
| Route | What it can do | What it cannot assume |
|---|---|---|
| Managed browser | Launch a separate OpenClaw-owned Chrome profile and produce repeatable browser state. | It doesn't inherit the cookies or tabs in everyday Chrome. |
| Browser Relay | Operate eligible tabs in an approved signed-in Chrome profile. | It can't bypass tab access, Chrome exclusions, MFA, or site policy. |
| Remote CDP | Connect OpenClaw to a separately provisioned browser endpoint. | It doesn't make endpoint exposure or credentials safe by default. |
What must be ready before installation?
As of September 10, 2026, the official Chrome extension page names three checks that belong before troubleshooting: a current OpenClaw CLI, a supported Chrome-family browser, and a running Gateway or browser node for the selected pairing. The current npm release added a fourth in our test: Node 24.16.0 or newer for OpenClaw 2026.9.3.
node --version
openclaw --version
openclaw browser extension status --json
openclaw browser profiles --json
Use the official OpenClaw Chrome extension documentation and verify the Chrome Web Store publisher before installing. A GitHub fork can be useful for research, but it doesn't define the official ID, permission model, or default behavior.
How do you install and connect OpenClaw Browser Relay?
Run the installer and keep the terminal open while Chrome completes its side of setup. On macOS, the command registers the native host and requests the Store extension. Chrome may require a full quit and reopen before it shows the request. OpenClaw doesn't approve Chrome's permission prompt for you.
openclaw browser extension install --json
openclaw gateway run
openclaw browser --browser-profile chrome tabs --jsonThat failure exposed a practical rule: don't replace identity checks with a random unpacked copy when the Store path is required. Finish Chrome's official approval flow, then verify the connected tab.
How do you verify the extension, Gateway, relay, and tab?
A good verification walks from the host outward. Our first doctor run failed because Gateway credentials were absent. After starting an isolated token-authenticated Gateway, the endpoint and plugin passed while the managed browser correctly remained not running. Starting that browser changed all seven doctor checks to pass. That control case proved the service worked, but it did not prove Relay connectivity.
# Layer 1: Gateway and browser service
openclaw browser doctor --json
# Layer 2: extension files and native host
openclaw browser extension status --json
# Layer 3: extension-backed profile
openclaw browser --browser-profile chrome tabs --json
# Layer 4: reversible action on the intended test tab
openclaw browser --browser-profile chrome snapshot --efficient| Layer | Passing evidence | What it still doesn't prove |
|---|---|---|
| Gateway | doctor says browser control endpoint reachable | No Chrome tab is attached yet. |
| Native host | registration state is owned and extension ID is approved | The extension may still be paused or disconnected. |
| Relay profile | chrome profile reports the expected tab | The tab may be the wrong account or page. |
| Task result | A low-risk action changes the intended test page and a second read confirms it | One success doesn't prove every site or future release. |
How do you diagnose common Relay failures?
Diagnose the first failing layer. Reinstalling the extension can't repair a missing Gateway token, and rotating a token can't approve a Chrome extension.
| Symptom | Likely layer | Next check |
|---|---|---|
| CLI exits before starting | Runtime | Compare node --version with the current package engine requirement. |
| GatewayCredentialsRequiredError | Gateway authentication | Pass the approved token or password and confirm the same config path is in use. |
| manualSetupRequired=true | Chrome approval or native host | Inspect installedCopy, registrations, Store request, discovered IDs, and Chrome approval separately. |
| chrome tabs returns an empty list | Relay or tab access | Open extension Settings, verify connected state, access mode, intended profile, and selected tab. |
| Wrong tab disappears after mode change | Selected tabs policy | Confirm the tab remains in the OpenClaw group and hasn't moved to an excluded URL. |
What permissions and evidence are safe to share?
The extension can inspect and operate the content of an eligible attached tab. Treat screenshots, snapshots, URLs, and console output as account data. Use a test page, redact names and tokens, and capture only the layer needed to prove the result.
Where does ego (lite) fit, and where does it not?
ego (lite) is a different browser execution route for coding agents. The ego-browser skill runs JavaScript workflows inside a dedicated Space and can use eligible, user-authorized browser state without turning the task into an OpenClaw Gateway or Relay setup. In our September 10 QA run, one Space checked eight article pages at desktop and 390-pixel mobile widths, verified headings, images, anchors, code overflow, canonicals, and a real outline click.
That doesn't fix OpenClaw. Use the ego (lite) quick start when the actual requirement is an independent browser workspace for Claude Code, Codex, or another coding agent. Stay with OpenClaw when the workflow depends on its Gateway, agent system, channels, or browser CLI.
FAQ
Is OpenClaw Browser Relay the same as the managed browser?
No. Relay connects eligible tabs from an approved Chrome profile through the extension. The managed route launches an OpenClaw-owned profile with separate state.
Does extension install success prove the Relay is connected?
No. Confirm the native host, live extension state, extension-backed profile, intended tab, and one reversible after-state.
Why does openclaw browser tabs return an empty list?
An empty list usually means no eligible tab is attached to that profile. Check the extension connection, access mode, profile selection, tab group, and excluded URL rules.
What caused GatewayCredentialsRequiredError in our test?
The CLI reached a Gateway operation without an approved token or password. Starting an isolated token-authenticated Gateway fixed that layer, then doctor exposed the next state instead of repeating the credential error.
Can Relay control incognito or chrome:// pages?
The September 10 official documentation excludes incognito, chrome://, chrome-extension://, and tabs without a usable URL. file:// also needs Chrome's separate file-access permission.
Does the Gateway token belong in a screenshot?
No. Redact tokens, cookies, account names, and private URLs. OpenClaw's JSON status is designed to omit relay keys and pairing strings, but review output before sharing it.
Can Edge use the same extension?
This guide doesn't claim Edge support because our September 10 run used Google Chrome 152 on macOS. Follow the current official browser support statement before extending the steps to another Chromium browser.
How do you remove the native host after a test?
Run openclaw browser extension uninstall-host, then inspect extension status again. Our cleanup removed eight owned artifacts and returned all four registration entries to missing.
Can ego (lite) repair a broken OpenClaw Relay?
No. ego (lite) is another execution environment for browser work. It doesn't repair OpenClaw tokens, native-host registration, Gateway pairing, or extension state.
