Vessel: app and UI for Hermes Agent

AI browser that shows every action in a real window for Hermes, OpenClaw or any provider

What Vessel does

Instead of running automation invisibly, Vessel renders pages like a normal browser so the AI's navigation, form-filling and research are visible as they happen; you can approve sensitive actions once or for a scoped run or domain, reject with steering, undo recent changes, or take over manually at any point. Durable conversation threads, a cross-source run inbox, named sessions, checkpoints, notes, bookmarks and page-change tracking make longer, interrupted browsing work recoverable rather than lost when a session ends.

Power users reach the same foundation through a Command Bar for harness-driven workflows, a Supervisor Sidebar with ten live tabs, and support for external agents, MCP clients and browser-automation tooling, with a built-in chat assistant covering Anthropic, OpenAI, Ollama, llama.cpp, Mistral, xAI and other providers. Linux is the most mature install target today; macOS release packaging is available building from source, and the project describes itself as early software.

Key features

Visible, real-browser-window automation instead of a hidden headless run
Approve, reject-with-steering or undo controls over AI-driven browser actions
Durable sessions, checkpoints, notes and bookmarks for interrupted multi-day research
Command Bar and Supervisor Sidebar for harness-driven and MCP-client workflows
BYOK support for Anthropic, OpenAI, Ollama, llama.cpp, Mistral, xAI and more

When to use it

Running longer AI-assisted research sessions that survive being closed and reopened
Letting a Hermes or OpenClaw agent browse and fill forms with visible human approval
Connecting an external MCP client to a real, supervised browser instead of a headless one

Who it is for: People who want AI-assisted browsing they can watch and interrupt, and developers who want MCP or agent access to a real, supervised browser.

How it fits with Hermes Agent

Vessel lists Hermes Agent, alongside OpenClaw, as a supported way to drive the browser, in addition to connecting any other API provider directly.

FAQ

What is Vessel?

Vessel is an AI-assisted web browser built on Chromium that keeps every AI action visible in a real browser window, so you can watch, approve or redirect the work instead of guessing what a hidden automation run did.

Does Vessel work with Hermes Agent?

Yes, it is described as usable with Hermes Agent or OpenClaw, and it also connects to any other API provider you supply directly.

How do I install Vessel?

The fastest path is the Linux AppImage from GitHub Releases; it is also available with npm install -g @quanta-intellect/vessel-browser, or by running npx @quanta-intellect/vessel-browser without installing it.
