README

Vessel: Your Agent's Browser

Open source chromium-based browser for persistent web agents. Linux is the most mature install target today, and macOS release packaging is available from source.

Vessel gives external agent harnesses a real browser with durable state, MCP control, and a human-visible supervisory UI. It is built for long-running workflows where the agent drives and the human audits, intervenes, and redirects when needed.

Built for agent harnesses such as Hermes Agent, OpenClaw, and other MCP clients
Keeps browser state alive with named sessions, pinned tabs, editable/exportable bookmarks, annotated checkpoints, action undo, and structured page visibility
Keeps humans in the loop with approvals, runtime controls, and a visible browser instead of a headless black box

Vessel is in active development and currently makes no security assurances. Use and deploy it with care.

Fastest Install Today

Linux AppImage from GitHub Releases:

Download the latest Vessel-<version>-x64.AppImage
Mark it executable: chmod +x Vessel-*.AppImage
Launch it: ./Vessel-*.AppImage
Open Settings (Ctrl+,) and confirm the MCP endpoint shown there

Install via npm

npm install -g @quanta-intellect/vessel-browser
vessel-browser

Or run it directly without installing:

npx @quanta-intellect/vessel-browser

Source Install

curl -fsSL https://raw.githubusercontent.com/unmodeled-tyler/quanta-vessel-browser/main/scripts/install.sh | bash

Development From Source

Vessel development uses Node.js 22. If you use fnm, run fnm use from the repo root to pick up .node-version.

fnm use
npm install
npm run dev

If you want extra local AI tracing in development, create an optional src/main/telemetry/trace-logger.local.cjs file. Vessel will load it only in local dev builds, and packaged production builds ignore it.

Why Vessel?

Most browser automation stacks are either headless, stateless, or designed around a human as the primary operator. Vessel is built around the opposite model: the browser is the agent's operating surface, and the human stays in the loop through a visible interface with clear supervisory controls.
