Comparison

Claude in Chrome extends Claude. Browsentic extends your browser.

Anthropic ships an extension that puts Claude in a Chrome side panel. Browsentic starts from the other end: the browser you already use, handed to whichever agent you already run. Same idea, different owner. Here is the honest version of where they overlap, where each one wins, and how to pick.

Different owners

The same idea, pointed in opposite directions

Claude in Chrome

Claude, extended into your browser

  • Anthropic’s agent, thinking in Anthropic’s cloud, acting through a Chrome side panel
  • Included with the paid Claude plans: Pro, Max, Team and Enterprise
  • One click to install from the Chrome Web Store
  • At home if you already live in claude.ai and want the same Claude everywhere

Browsentic

Your browser, extended into the agent you already run

  • Runs on the agent CLI you already pay for: Claude Code, Codex or Antigravity, switchable in one click
  • No account, no API key, no cloud service, no telemetry
  • Doubles as an MCP server, so Claude Code, Cursor or Zed drives the same logged-in tab
  • MIT licensed and source available, on Chrome and every Chromium browser

Side by side

The whole thing, in one table

Checked against Anthropic's own announcement and help center, August 2026. Their product moves; when this table drifts, an issue is the fastest fix.

Browsentic Claude in Chrome
The shape of it
The agent Claude Code, Codex or Antigravity, your pick Claude
Where it thinks On your machine; the daemon binds to loopback In Anthropic’s cloud
What it costs Nothing beyond the agent subscription you already have A paid Claude plan
Browsers Chrome, Edge, Brave, Arc: any Chromium browser Google Chrome only
Source MIT licensed, source available Proprietary
Who else can drive Any MCP client: Claude Code, Cursor, Zed share one browser Claude apps only
On the page
Read, click, type, submit Yes, and anything consequential asks first Yes, with vendor safeguards
Console and network Yes: errors, failed requests and timings, read over Chrome’s debugger Yes
Files Both directions, each gated: downloads land sealed, uploads ask first Both directions
Show it a job once Recordings: do it yourself, later say “do it like last time” Workflow recording, in the classic panel
Site knowledge Site maps: it explores any site and keeps notes, intranets included Built in for Gmail, Slack, Calendar, Docs and GitHub
While you are elsewhere
Scheduled jobs Kept in the extension; survives the agent, the client and the daemon Kept in Claude’s cloud
Long jobs Background monitors track progress without an agent or a token An agent has to keep looking
The obvious commands “Go back” and “open github.com” run locally, in milliseconds Every instruction is a model round trip
Voice Dictate in the panel, press to talk in the popup Type
Trust
Credentials Sealed into placeholders; the agent never sees plaintext 1Password integration; declines sensitive entry
Approvals A declarative policy, every rule tunable, per-site grants Ask before acting, or autonomous with fixed safeguards
Prompt injection Containment: scoped runs, a sealed agent, page text marked untrusted Detection: trained classifiers watch for suspicious patterns

No equivalent over there

What only Browsentic does

Bring your own agent

It runs on the CLI you already pay for and are already signed in to, and switching between Claude Code, Codex and Antigravity is one click in the popup. No second subscription, and no bet on a single vendor.

An MCP server, not just a panel

The daemon speaks MCP over stdio, so Claude Code, Cursor and Zed can take the wheel of the same real, logged-in tab. One browser, shared by every client you use.

The obvious commands cost nothing

“Go back”, “scroll to the top” and “open github.com” are scored against a local grammar first and run in the browser in milliseconds. No model is woken for the things a model adds nothing to.

Monitors that outlive everything

Watching an upload or a deploy runs in the extension itself. It keeps going when the agent finishes, the MCP client disconnects, or the daemon goes away, and it burns no tokens while it waits.

Dark mode with a measurement behind it

It reads what a page paints, scores contrast against WCAG, and rethemes on the page’s own terms, preferring the dark hook the site already defines over inverting everything.

Credentials the agent cannot read

A deterministic sanitizer runs on both sides of the socket. Passwords, keys, tokens and card numbers become sealed placeholders before the agent sees them, and turn back into plaintext only inside the field they are typed into.

Credit where it is due

What Claude in Chrome does that we do not

A comparison you cannot lose is not a comparison. These four are real, and two of them are why some people should pick their product over ours.

One click to install

The Chrome Web Store, versus our npx command plus a trip through chrome://extensions. Their funnel is genuinely smoother, and we know it.

Reach beyond the browser

Through Claude Desktop it can touch local files and computer control. Browsentic deliberately stops at the tab: the spawned agent gets browser tools and nothing else.

Injection classifiers

Anthropic runs trained classifiers that watch for suspicious instruction patterns. We do not. Our answer is containment: scoped runs, a sealed agent, page text marked untrusted. Both are partial; theirs detects, ours limits the blast radius.

Enterprise administration

Team and Enterprise admins get org-wide allowlists and blocklists. Browsentic has per-site grants on one machine, and nothing fleet-wide.

The short version

How to pick

Pick theirs

Pick Claude in Chrome if you live in claude.ai, want one-click installation, and are happy inside Anthropic’s walls. It is a polished product with real safety work behind it.

Pick ours

Pick Browsentic if you already run an agent CLI, want the same browser reachable from your terminal and your editor, browse in Edge, Brave or Arc, or want the whole thing local, inspectable and MIT licensed.

Nothing stops you running both. They drive different tabs and answer to different masters.

Stop describing the page. Hand it over.

Free and MIT licensed. Nothing to sign up for, no key to paste, and a fresh install connects to nothing until you redeem a pairing code yourself.
