My Hermes Agent OS GitHub verdict is simple: the Herald OS repo at github.com/iamlukethedev/Herald-OS is the cleanest interface I've seen for Hermes Agent, but it's alpha software and it shows in a couple of places.
Herald OS is a free, open-source operating system that uses Hermes Agent as the interface for everything.
You talk or type to Hermes, and it works across the whole machine.
I installed it, used every page, and scored each part honestly below.
You'll get the repo facts, every install route, a feature-by-feature review, a comparison with Hermes Desktop, the problems I hit and who should install it.
The Verdict On Hermes Agent OS GitHub In One Table
I'd give Herald OS 4 out of 5 overall, and here's how each area scored.
| Area | My score out of 10 | Why |
|---|---|---|
| Design and polish | 9 | It's super clean, and I think it looks nicer than Hermes Desktop. |
| Hermes integration | 9 | It runs your normal Hermes install, so my automations synced across quickly. |
| Organisation | 9 | Spaces finally answer the "separate clients" question I get every week. |
| Settings depth | 8 | Almost everything is adjustable, from runtimes to voice speed. |
| Safety controls | 8 | Approval tiers, auto-approve and an audit log are all built in. |
| Install experience | 7 | There are six routes, but the Mac build needs a quarantine command. |
| Connections | 3 | The page didn't work or sync for me in this alpha. |
| Maturity | 5 | It's version 0.1, released on 6 October 2026, so expect rough edges. |
The headline is that the core experience is excellent and the edges are unfinished.

What Is In The Hermes Agent OS GitHub Repo?
The repo's description calls Herald OS an agent-native operating system with Hermes Agent as the interface.
These are the facts I checked in the repo and the GitHub API on 8 October 2026.
| Item | Detail |
|---|---|
| Repo | github.com/iamlukethedev/Herald-OS |
| Author | Luke The Dev, an independent developer |
| Affiliation | None, because the README says it isn't affiliated with Nous Research |
| Licence | MIT |
| Status | Alpha (0.1) |
| Latest release | v0.1.0-alpha.1, published 6 October 2026 |
| Stars and forks | 155 stars and 20 forks when I checked |
| How it plugs in | A standard Hermes install plus a Hermes plugin called herald-os-bridge |
Herald OS doesn't fork Hermes Agent.
Nous Research's own repo, github.com/NousResearch/hermes-agent, stays separate, and Herald OS runs on top of whatever version you've installed.
How To Install Herald OS From GitHub
Every route needs Hermes Agent and a model provider first.
curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
source ~/.zshrc
hermes setup
The provider can be a Nous Portal account or an API key for OpenRouter, OpenAI, Anthropic, a local model and others.
Then pick your route from the releases page.
| Route | Key commands or files | My take |
|---|---|---|
| Mac app | The mac-arm64 DMG, then xattr -dr com.apple.quarantine "/Applications/Herald OS.app" |
This is the quickest way to try it, on macOS 13 or later with Apple Silicon. |
| Herald OS Linux | Join the two ISO parts with cat, check the sha256, then write it to an 8 GB USB stick |
This is the full OS on Fedora, with updates you can roll back. |
| Arch | makepkg -si in packaging/arch/herald-os-bin, then herald-os setup |
It's not on the AUR yet, so you build it from the repo. |
| Omarchy | The Arch package, then herald-os omarchy install |
It follows Omarchy's theme and adds Super+Alt shortcuts. |
| Other Linux | Unpack the tarball to /opt/herald-os, then herald-os setup and herald-os-app |
It runs as an app inside your current desktop. |
| Virtual machine | brew install qemu zstd, then bash linux/vm/try.sh |
It boots the whole OS on an Apple Silicon Mac. |
On a Mac, Herald OS takes over the screen, so Cmd+Ctrl+F toggles fullscreen and Cmd+Q quits.
I'll be honest about how I installed it.
I asked Claude to set it up, and it was done in about two minutes.

Herald OS Features Reviewed One By One
Dashboard: 9 out of 10
The dashboard greets you with "Good morning, Julian. Your day already in motion."
It shows today's schedule from your scheduled tasks and a section called "here's what needs attention".
Voice input sits right there, so you can talk instead of typing.
Recent screenshots from your desktop show up too, which I found surprisingly useful.
Pick up where you left off: 8 out of 10
Hermes looks at the names of your recent documents, projects, chats and calendar events, then suggests where to continue.
You can toggle it on or off.
The README says it reads names and dates rather than file contents, and that it's off until you switch it on.
I'd knock a point off only because it sends those names to your model provider, so privacy-minded users should check the exclusions first.
Chat: 8 out of 10
The chat is normal Hermes chat with two extras called Preview and Sources.
Sources let you add files that Hermes can read, and you can start a new conversation any time.
Spaces: 9 out of 10
Spaces split your work into Ideas, Work and Personal.
You can add new spaces, such as one per client, and set a default space.
This is the best answer I've seen to the question I get inside the AI Profit Boardroom about running separate companies and clients from one Agent OS.
Missions: 8 out of 10
Missions let you give Hermes an active goal, like building out a new website.
It plans the work step by step, so you're managing a project rather than firing off prompts.
Memory: 7 out of 10
The Memory page shows everything Hermes remembers about you.
It's useful, but it surprised me, because my Telegram details were sitting right there on screen.
Be careful what you screen-share.
Files: 8 out of 10
Files covers recent, favourites, projects, downloads, shared and deleted.
It's simple and it works.
Automations: 9 out of 10
You can manage automations and switch them on or off.
Mine synced across Herald OS, Hermes Desktop and my Agent OS, because it's the same Hermes underneath.
That included a daily 6am to-do recap, a daily Japanese lesson and morning inbox triage.
Connections: 3 out of 10
Connections is where tools, apps and external connections are meant to live.
It didn't work or sync for me.
That's the nature of open-source alpha software, and I could have asked Claude to fix it, but it's the weakest part right now.
Settings: 8 out of 10
The settings are deep, and this is where Herald OS feels like a real operating system.
| Settings area | What you can change |
|---|---|
| Model | Your preferred model, which showed GPT-6 Astra on my machine through a CLI |
| Agents | Where agents run tasks, including Docker, and how many background agents you allow |
| Behaviour | Remember preferences, auto-approve on or off, and activity history for background work you forgot |
| General | Launch fullscreen, default space, default projects folder, do not disturb, stay awake, screen saver, dictation and quit session |
| Look | Colours and themes |
| Software access | Coding agents and local models such as Claude Code, Codex and LM Studio, which you can add or remove |
| Plugins | Paste a GitHub link to add a plugin |
| Hermes Agent | A section for Hermes itself |
| Usage | Tokens used, your plan and your token balance |
| Voice | Voice engine, speed, local or live voice, a test button and a list of voice commands |
| Everything else | Privacy, notifications, networks, storage and accessibility |
Do not disturb mutes a bell notification sound, which I was glad to find.
The voice setup feels a bit like Jarvis once it's tuned.
Interface quality: 7 out of 10
The sidebar is resizable, which is nice.
But the interface was cut off slightly at the top on my screen, which is a classic alpha rough edge.

Herald OS Vs Hermes Desktop
Both run the same Hermes Agent underneath, so this is really a choice of interface.
| Question | Herald OS | Hermes Desktop |
|---|---|---|
| Who makes it? | Luke The Dev, independently | It's a separate desktop app for Hermes |
| Does it look good? | Yes, and I think it looks nicer | It's clean but more of a chat app |
| Does it organise work? | Yes, with Spaces, Missions and a dashboard | It's mainly profiles and chats |
| Do automations sync? | Yes, because it shares the same Hermes | Yes, because it shares the same Hermes |
| Is it mature? | No, it's alpha 0.1 | I've used it for longer, so it feels steadier to me |
| Is it free? | Yes, under MIT | Yes |
Back in March and April, the old way was Hermes in a terminal, and it was messy.
Both of these are the new way, and Herald OS is the prettier of the two.
If you like adding abilities, the Hermes Agent plugins marketplace works alongside either one.
The Problems I Hit With Herald OS
The Mac build isn't notarized by Apple yet, so macOS blocks it until you run the xattr quarantine command.
Connections didn't work or sync for me.
The interface was cut off slightly at the top of my screen.
The README itself tells you to keep backups of anything you let an agent touch.
The repo's own known limits say the Linux ISO has been tested in a virtual machine but not yet on real PC hardware.
None of these stopped me using it, but they're why it gets 4 out of 5 and not 5.
Updates, Rollback And Reporting Bugs
On Herald OS Linux, herald-os update installs a new version and herald-os rollback takes you back.
On a Mac, you download the new DMG and replace the app.
On Arch and Omarchy, you run git pull and makepkg -si again, and from source you run git pull and npm run bootstrap.
To report a bug, open an issue on the repo, and the template asks for what happened, steps, platform, versions and logs.
Security issues go privately through the repo's Security tab, not in a public issue.
Model and provider problems belong on the Nous Research hermes-agent repo instead.
Who Should Install Herald OS From GitHub?
You should install it if you already use Hermes Agent and want a beautiful interface without giving up your setup.
You should install it if you juggle several clients or businesses and want Spaces to keep them apart.
You should wait if you need everything rock solid today, or if you rely on Connections for your workflow.
