Best UI For Hermes Agent (2026): 7 Interfaces Ranked

The best UI for Hermes Agent in 2026, for the way I work, is my own Agent OS, and the best free one is Hermes Desktop from Nous Research.

The Agent OS is my own product, so weigh that, and note that I rank it first but refuse to give it a number in my own scores table.

Hermes Desktop scores 8.8 out of 10 as my top third-party pick, and Herald OS is next at 8.3 because it is the best-looking Hermes interface I've used.

That is the verdict, and the full ranking of all seven interfaces is right below, feature by feature.

Top 3 Picks At A Glance

• 🥇 Agent OS is my number one for daily use, because it is one cockpit for Hermes, Claude and my other agents, and it is my own product inside the AI Profit Boardroom.
• 🥈 Hermes Desktop is the best free UI for Hermes Agent at 8.8 out of 10, because it is official, stable and cross-platform.
• 🥉 Herald OS is the best-looking interface at 8.3 out of 10, although it is still an alpha.

What Counts As A UI For Hermes Agent

Hermes Agent is the free, open-source AI agent from Nous Research.

A UI for Hermes Agent is anything that puts a screen on top of that agent, so you can chat with it and manage it without memorising commands.

The official docs say the front-ends talk to the same agent and share state.

That means you can start a session in one interface and resume it in another.

For this ranking I counted native apps, browser apps, a multi-agent dashboard, a 3D office and the terminal itself.

Read This First: How This Verdict Differs From My Last One

I have already reviewed nine free interfaces in my earlier ranking of the free Hermes UIs.

In that review, Hermes Desktop came first, Herald OS came second, and my own Agent OS sat in a "not scored" box at the bottom.

I wrote there that scoring my own product in my own ranking would not be fair, and I still believe that.

So here is the honest position for this post.

That list ranks free downloads, and this list ranks what I actually use every day.

The interface I use every day is the Agent OS, so it is first here, with a disclosure in the opening lines.

I have still not given it a score, and every number in the table is carried over unchanged from the earlier review.

If you only want free tools, read this page from number two downwards and the order matches the old one.

How I Scored Each UI For Hermes Agent

I gave each third-party interface a score out of 10 on four things.

Setup is how quickly you can install it and send a first message.

Stability is how reliable it felt during my own use.

Features is how much of Hermes you can control from it.

Look and feel is how pleasant it is to work in for hours.

The overall verdict is my own weighing of those four, with stability counting most.

These are opinion scores from my own use, and nobody measured them with a tool.

The 7 Best UI Options For Hermes Agent, Reviewed

1. Agent OS — My Daily Pick (My Own Product, Unscored)

The Agent OS is my AI agent operating system, which is a local dashboard where every agent I use is a page in one app.

What it is: It is one cockpit for Hermes, Claude Code and my other agents, with a shared memory underneath.

Mission Control: The home page shows the live status of every agent, what is running and what happened since I last looked.

Agent pages: Each agent has its own section with a chat panel, a file workspace and a control room.

The Hermes desk: One Hermes sits behind thirteen rooms, which are Chat, Apollo voice, Oracle, Astros, Studio, Sessions, Outreach, Mixture, Workspace, MCPs, Manage, Control Room and Goal Mode.

Profile chips: Every Hermes profile on the machine appears as a chip in the chat, and each chip has its own model, memory and rules.

Voice: The wake word is "hey Hermes", it listens in the browser, and spoken answers come back in about five seconds and land in the same chat thread.

Board: A kanban board turns bigger jobs into tickets, and a dispatcher starts a Hermes worker for each one.

Memory: Every exchange saves into an Obsidian vault of plain text files, and every agent reads that vault before it works.

Manage: The full Hermes dashboard is embedded, so sessions, models, cron jobs and skills need no terminal.

Phone: The same dashboard opens on a phone through Tailscale, in a layout built for a thumb.

Best for: It is best for people who run Hermes next to Claude or other agents and want one memory across all of them.

Cost: It is included with AI Profit Boardroom membership, and there is no public GitHub repo.

How to get it: Members download an installable zip and follow the install video.

What I don't like: It is not a free download, it runs on your own machine so remote access depends on your home internet and power, and thirteen rooms is more than a beginner needs.

I explain why it is not a public repo in my post on the Agent OS and GitHub.

2. Hermes Desktop — Verdict 8.8/10

Hermes Desktop is the native desktop app built by Nous Research, the team behind Hermes Agent.

The docs describe it as the same agent core and settings as the command line, driven through a modern interface.

You get chat with streaming tool output, a preview rail for web pages and files, a file browser, voice, cron, profiles, skills and settings.

The plugin marketplace is a big part of the score, because I found around 500 free community plugins that install in one click.

Best for: It is best for almost everybody who wants a free interface.

Cost: It is free and open source.

How to get it: You download it from the official page, or you run hermes desktop on a machine that already has Hermes.

What I don't like: Voice permissions were hit and miss on my Mac in June, and the design is functional rather than beautiful.

→ Get Hermes Desktop

3. Herald OS — Verdict 8.3/10

Herald OS is an agent-native operating system with Hermes Agent as the interface, built by an independent developer called Luke The Dev.

It opens on a dashboard that greets you, shows today's schedule and offers a "Pick up where you left off" card.

It organises work into Spaces and Missions, and it has full pages for Memory, Files and Automations.

Best for: It is best for people who want the nicest-looking screen for Hermes alone.

Cost: It is free under the MIT licence, and it is not an official Nous Research product.

How to get it: You install Hermes first, then download the build from the GitHub releases page.

What I don't like: It is an alpha, the top of the interface was slightly cut off on my screen, and the Connections page did not sync for me.

→ See Herald OS on GitHub

My full review is in my Herald OS verdict.

4. Hermes WebUI — Verdict 8.0/10

Hermes WebUI is a lightweight web app by nesquena.

The project says it aims for full parity with the command line, and it needs no build step because it is plain Python and JavaScript.

It has a three-panel layout with sessions, chat and a workspace file browser.

Best for: It is best for running Hermes on a server and using it from a phone.

Cost: It is free under the MIT licence.

How to get it: You clone the repository and run python3 bootstrap.py.

What I don't like: Remote access is your job to secure, usually through an SSH tunnel or Tailscale.

→ See Hermes WebUI on GitHub

5. Hermes Workspace — Verdict 7.9/10

Hermes Workspace is a browser command centre by outsourc-e.

It combines chat, memory, skills, files, a terminal and a kanban task board.

Version 2 was the release where I started relying on it, because it added profiles, a live inspector and an editable memory browser.

Best for: It is best for people who want a free board and inspection tools for Hermes.

Cost: It is free under the MIT licence.

How to get it: You run its one-line installer, and it needs Node 22 or later.

What I don't like: It needs the Hermes gateway and dashboard running behind it, so setup takes longer.

→ See Hermes Workspace on GitHub

6. The Terminal And TUI — Verdict 6.5/10

The terminal is where Hermes began, and the modern terminal UI opens with hermes --tui.

The docs call the TUI the recommended way to run Hermes interactively.

It scores top marks for setup and features, because nothing else needs installing and nothing is hidden.

Best for: It is best for developers and remote servers.

Cost: It is free, because it ships with Hermes.

How to get it: You install Hermes and run the command.

What I don't like: It is the least friendly screen on this list, which is why its look and feel score drags the verdict down.

7. Hermes3D — Unscored, Because I Have Not Tested It

Hermes3D is a 3D virtual office for AI agents that you run on your own infrastructure, built by LukeTheDev.

I have not installed it, so this section is a summary of its GitHub README and not a review.

The README calls it an independent, community-driven front-end that is not affiliated with the teams behind the agent backends it connects to.

It describes a shared 3D office where you watch agents work in real time, a 2D pixel office for low-power machines, standups, pull request review, a kanban view, fleet chat and approvals.

It connects to Hermes through a bundled gateway adapter, and it also has a demo gateway that needs no agent at all.

One thing to know is that the repository's short About line calls it a 3D engine for games and simulations, while the README describes an office for agents.

Best for: It may be best for people who want to see a team of agents as a place, once they have tried it.

Cost: It is free under the MIT licence.

How to get it: You clone the repository and run it with Node.js 20 or later, and it does not install Hermes for you.

What I'd check first: It has one release from August 2026 and no pushes since late August, so check the repo for activity before you rely on it.

Feature-By-Feature Verdict On The Top Five

Agent OS vs Hermes Desktop: The Head-To-Head

This is the comparison that matters most for this keyword, so here is my straight answer.

Hermes Desktop wins on cost, because it is free and the Agent OS needs a membership.

Hermes Desktop wins on simplicity, because it is one app with one agent.

Hermes Desktop also wins on trust, because it is the official app from the people who make Hermes.

The Agent OS wins when Hermes is not your only agent.

My heavy building runs through Claude Code, and my long-running jobs run through Hermes.

In the Agent OS those are two pages of one app that read the same vault, so I never explain my business twice.

The Agent OS also wins on voice for me, because the wake word sits in the browser and re-arms itself each visit.

The two are not rivals in practice, because both sit on the same Hermes install.

I still keep Hermes Desktop installed, and you should start there if you are new.

Interfaces I Left Off This List

I kept this ranking to seven so that it stays useful.

The built-in admin panel that opens with hermes dashboard is a settings screen more than a daily interface, and I cover it in my Hermes Agent dashboards roundup.

Hermes Pixel Office, StarNet and Hermes Cloud are all reviewed and scored in my earlier ranking of the free interfaces.

I have not repeated them here, because nothing about my view of them has changed.

How To Choose The Right UI For Hermes Agent

Choose Hermes Desktop if you are new, because it is free, official and hard to break.

Choose the Agent OS if you already run two or more agents and want one screen and one memory.

Choose Herald OS if looks matter most and you can live with alpha rough edges.

Choose Hermes WebUI if your agent lives on a server and you want it on your phone.

Choose Hermes Workspace if you want a free kanban board and a live inspector.

Choose the terminal if you are a developer and speed matters more than comfort.

Leave Hermes3D as a weekend experiment until you have tested it yourself.
