A web UI for your terminal agent, written like it’s 2008

What it does

Hermes WebUI is a browser-based dashboard for the Hermes Agent, a self-hosted autonomous agent that remembers context across sessions and runs scheduled jobs while you are offline. The app replicates the terminal experience in a three-panel layout—sessions on the left, chat in the center, and workspace files on the right—so you can manage the agent from a browser or your phone without maintaining a separate configuration.

The interesting bit

The entire frontend is built with vanilla JavaScript and Python; there is no framework, no bundler, and no build step. In an ecosystem of 500-node-module dashboards, this is either refreshing restraint or stubborn minimalism, but it means you will not be debugging a Vite config when the agent misbehaves.

Key highlights

• Promises full parity with the Hermes CLI, including streaming responses, inline tool-call cards, subagent delegation, Mermaid diagrams, and approval flows for dangerous shell commands.
• Connects to your existing Hermes agent and models over an SSH tunnel; no extra provider keys or model setup is required.
• Session management supports projects, colored tags, archiving, pinning, and full-text search; new messages automatically queue while a turn is still streaming.
• A circular token-usage ring in the composer footer tracks context and cost at a glance, and a dedicated Control Center houses all settings and session tools.

Caveats

• Native Windows is not officially supported for the automated bootstrap; a community-maintained native setup exists, but POSIX-style file paths and bash-dependent agent tools can leak into the workspace browser.
• The optional Gateway-backed chat mode is still transitioning: attachments, cancellations, and approvals may not yet match behavior on other messaging surfaces.

Verdict

Worth a look if you already run Hermes Agent and want a no-frills, self-hosted web dashboard that stays out of your way. Skip it if you need a standalone cloud service or a polished native Windows installer.
