Xplor — The Grok-Native Browser

Features

A browser that does the work.

Grok doesn't just chat in a sidebar — it drives the browser, organizes your tabs, and runs tasks while you keep going.

Agentic Grok side panel

A built-in Grok that doesn't just chat — it drives your browser: opens and organizes tabs, browses for you, with its thinking shown live as it works.

Auto-organized tab groups

Your tabs sort themselves into tidy, topic-named groups the moment an agent opens them. Or just say “organize my tabs” and Grok groups them by what they are.

Scheduled & background tasks

Schedule Grok to run a task on a repeat or at a set time, and watch it from the sidebar. Background agents work in hidden tabs and never steal your focus.

The “Grok it” button

A floating Grok button on every page. Summarize the long read, fact-check the claims (“Is this true?”), explain it, or turn it into an app — one click.

Grok Build

Describe an app in plain words and Grok writes it, then runs it live in a tab. Keep iterating just by chatting — every build keeps its own folder and conversation.

Grok Search home

New tabs open Grok Search. Type a query and it runs on grok.com with full context — Web and Imagine modes built in.

In-app auto-update

Xplor keeps itself current and verifies every byte before it installs — Sparkle on macOS, a verified in-app updater on Windows and Linux.

MCP & agent-ready

Xplor ships as an MCP server with an always-on local gateway, so agents like Grok, Claude, and Cursor can drive the browser natively — tabs, navigation, clicks, screenshots.

Agentic by default

Grok drives the browser, not just the chat.

The side panel opens tabs, organizes them, browses, and runs tasks in the background — while your active tab stays exactly where you left it.

An agentic Grok side panel Live

A built-in Grok that doesn't just answer — it drives your browser. Ask it to open and organize tabs or go research something, and watch its thinking stream live as it works. No extension, no copy-paste, no second window.

Tabs that organize themselves

The moment an agent opens tabs, they sort into tidy, topic-named groups — named by the conversation behind them — alongside native Bookmarks and Scheduled groups. Already drowning in tabs? Just say “organize my tabs,” and Grok looks at what's open and groups it by what it is.

▦ Auto-named groups — by conversation topic, the instant tabs open
★ Native Bookmarks group — always open, with a gear to the manager
↻ “Organize my tabs” — Grok regroups everything on demand

Scheduled & background tasks Live

Schedule Grok to run a task on a repeating interval or at a set time, and watch it from the Scheduled section of the sidebar. Background agents do their work in hidden tabs — a default-deny FocusArbiter guarantees your active tab never gets yanked away.

A few looks at Xplor doing its thing.

Build apps by describing them Ready

Type what you want on the Apps page and Grok writes the files for you — you watch it think and build in real time. The finished app runs live in a preview right beside the chat. Don't like something? Just tell Grok, and it edits the app in place, remembering everything from before.

The “Grok it” button

Every page gets a floating Grok button. One click and Grok works on what you're actually looking at — pick an action:

↳ Summarize this — the long read, in seconds
✓ Is this true? — fact-check the claims on the page
… Explain this — break it down in plain language
✦ Analyze / Build app from page — go deeper, or turn it into an app

All of Grok in one toolbar

A single glass toolbar follows you across Grok Build, Grok Web, Imagine, Groki, and X — even as an overlay on grok.com, x.com, and Grokipedia. Jump between Grok's services without leaving the page, and hide it whenever you want focus.

Make it yours

Your new tab, your backdrop.

Every new tab opens Grok Search on a beautiful landscape by default — or make it yours. Set your own background image for light and dark mode by drag‑and‑drop or browse, and Xplor remembers it. It switches automatically with your theme.

New tab with a custom light background — New tab with a custom **light** background

New tab with a custom dark background — New tab with a custom **dark** background

The background picker panel — The gear opens a per‑mode **background picker**

Drag and drop an image — **Drag & drop** any image — or browse your Mac

Built for agents, too

An API the agent layer deserves.

Xplor runs an always-on local gateway and ships as an MCP server — so any agent can drive it, with no launch flags and no setup dance.

# Always-on local gateway — no launch flags, no setup.
CDP        ws://127.0.0.1:9333     # Playwright / Puppeteer compatible
Agent API  http://127.0.0.1:9334   # navigate · text · click · type · screenshot · tabs

# …or register the bundled MCP server, and your agent
# (Grok, Claude, Cursor) gets native browser tools.

# Drive Xplor with your agent — no flags, no setup.

# 1. Discover the gateway: read ~/.xplorer/gateway.json
#    { "url": "http://127.0.0.1:9334", "cdp_url": "ws://127.0.0.1:9333", "token": "…" }
#    Send  Authorization: Bearer <token>  on every request (loopback-only, token-gated).

# 2. High-level Agent API — http://127.0.0.1:9334  (one round trip per action)
#    Tab ids come from GET /tabs, e.g. "12:0".
GET  /tabs                          -> { tabs: [ { id, url, title } ] }
POST /tabs               {url}       -> open a new tab
POST /tabs/{id}/navigate {url}       -> navigate (resolves on load)
POST /tabs/{id}/text                 -> { title, url, text }   # clean readable text
POST /tabs/{id}/axtree               -> accessibility tree     # ground click targets
POST /tabs/{id}/click    {selector}
POST /tabs/{id}/type     {selector, text}
POST /tabs/{id}/press    {key}       -> e.g. "Enter"
POST /tabs/{id}/screenshot           -> { data: "<base64 png>" }   # works on background tabs
POST /tabs/{id}/eval     {expression} -> run JS, awaits promises

# 3. Raw CDP — ws://127.0.0.1:9333   # point Playwright / Puppeteer here, no flags.

# 4. MCP (recommended): register sdk/xplorer_mcp.py (stdio, stdlib-only) and your
#    agent gets native tools — xplorer_tabs, xplorer_navigate, xplorer_read_text,
#    xplorer_click, xplorer_type, xplorer_press, xplorer_screenshot, xplorer_eval.
#    It auto-discovers the running browser via ~/.xplorer/gateway.json.

# Agents drive tabs while Xplor is in the background; hidden tabs stay live.

# Quick check (shell):
TOKEN=$(python3 -c "import json,os;print(json.load(open(os.path.expanduser('~/.xplorer/gateway.json')))['token'])")
curl -s -H "Authorization: Bearer $TOKEN" http://127.0.0.1:9334/tabs
