OpenClaw vs Hermes: Which Self-Hosted AI Agent Should You Run?
OpenClaw vs Hermes compared in plain language: memory, safety, apps and cost, which one to pick, and how to switch without losing anything.
OpenClaw vs Hermes is the question we hear most from people choosing a self-hosted AI assistant. Both are free and open source, both live in the chat apps you already use. What still separates them is what each one is built around, and how safe it is the day you install it.
OpenClaw vs Hermes: the short answer
Section titled “OpenClaw vs Hermes: the short answer”OpenClaw is an always-on hub. Your chat apps, your phone and your laptop all talk to that hub, and it decides which assistant answers. It shines when several people, several devices and several channels need to share the same assistants.
Hermes is a single assistant that keeps notes about you and gets better the longer you use it. It shines for one person, on a cheap server, doing the same kinds of work for months.
If you want one helper that improves over time, choose Hermes. If you want a shared hub for a team or a household full of devices, choose OpenClaw. Either way, keep it off the open internet. More on that below.
Side by side
Section titled “Side by side”| OpenClaw | Hermes | |
|---|---|---|
| Who makes it | A non-profit foundation with big-name sponsors | Nous Research, a company that also sells hosting |
| How you talk to it | WhatsApp, Telegram, Slack, Discord, iMessage and 20+ more | 27+ chat platforms, strongest in Chinese business apps |
| Does it remember you | Re-reads its notes every message; slower and pricier recall | Short notes always loaded, plus a searchable history |
| Does it improve itself | Yes, it can write and fix its own skills | Yes, and it goes further: it learns from experience |
| Safety out of the box | Trusts the operator; protective sandbox is off by default | Asks before risky actions; hides your secrets from code it runs |
| Apps and voice | Native Mac, iPhone, Android, Windows and Linux apps, voice wake-word | Desktop app for Mac, Windows and Linux; no phone apps from the makers |
| Community size | Larger, with the biggest add-on store | Smaller but growing faster |
| Paid hosted option | None from the makers | Yes, from Nous Research |
Both projects change almost daily, so treat this as a September 2026 snapshot.
Will it remember me?
Section titled “Will it remember me?”This is the clearest difference. Hermes keeps a short set of notes it reads every time, and it can search everything you have ever discussed when it needs an older detail. OpenClaw re-sends its whole notes file with every message, which costs more and makes finding old facts slower. One vendor test found Hermes recalled facts far faster, and an academic benchmark found Hermes did better with most of the AI models it tested. If you expect your assistant to know you well in six months, Hermes has the edge.
Which one is safer?
Section titled “Which one is safer?”Neither one is safe to leave on the open internet or to run on the computer that holds your passwords. Their records differ, though.
Serious flaws fixed this year. OpenClaw had several critical ones, including bugs that let a attacker take control of the hub. Hermes has a shorter list, though a few of its fixes are unclear in public databases. Keeping either one current is the first defence. Claworc publishes ready-to-use images for both and lets you update an instance with one click. Optionally backup your instance before the update.
Tens of thousands of OpenClaw installs found open on the internet. Security scanners counted more than a hundred thousand hubs reachable by anyone, many of them takeable. Better use Claworc to avoid such kind of incidents.
Malicious add-ons in the skill store. A security audit found roughly one in eight add-ons in OpenClaw’s store was malware, mostly password stealers. Hermes can install from the same store, so it inherits the risk.
Stored passwords and keys. Researchers found OpenClaw keeping AI provider keys in plain text files that common malware hunts for. Hermes hides secret-looking values from code it runs. Claworc sidesteps the problem for both: the agent only ever gets a stand-in key, and your real keys stay on the Claworc server.
Protection by default. OpenClaw ships with its protective sandbox switched off, and its own docs say the new team features are “not a security boundary.” Hermes asks permission before risky commands.
Microsoft’s security team put it bluntly this year: OpenClaw should be treated like untrusted software holding your passwords. That is fair for both projects, and it is exactly the problem Claworc is built to solve.
Which should I pick?
Section titled “Which should I pick?”| If you want… | Pick | Why |
|---|---|---|
| A personal assistant I’ll keep for years | Hermes | Its notes and self-written skills compound over time |
| An assistant on my Mac and phone, with voice | OpenClaw | Native apps and a wake-word; run it on a dedicated machine |
| Assistants my whole team shares | OpenClaw | Shared sessions and roles, with isolation added on top |
| Help writing and running code | Hermes | Works directly in your project and takes redirection mid-task |
| Recurring tasks that run on their own | Hermes | Scheduled jobs keep their memory between runs |
| Anything touching sensitive data | Neither alone | Run whichever you choose behind Claworc’s locked door |
Pick by the row that matches you, not by which project is more popular.
Can I switch later?
Section titled “Can I switch later?”Yes. Both projects ship a migration tool that imports the other’s notes, skills and settings, and they use the same format for skills. In Claworc, an OpenClaw agent and a Hermes agent are simply two instances in the same dashboard, with the same chat, browser, terminal and file manager. So switching is:
- Back up the current agent from the Backups page.
- Create a new instance and choose the other assistant.
- Restore the backup into the new instance, so the old notes are where the migration tool expects them.
- Run the migration from the built-in terminal.
- Check the notes files in the Files tab before pointing your chat channel at the new agent.
- Keep both for a week, then retire the one you like less.
For whoever administers it, the migration is a single command in either direction:
hermes claw migrate # OpenClaw -> Hermesopenclaw migrate hermes # Hermes -> OpenClawThere are no AI keys to move, because they never lived inside the agent: just tick the same models for the new instance. Reconnecting email or a calendar to the new agent is one sign-in popup.
The bottom line
Section titled “The bottom line”OpenClaw vs Hermes is a real choice: a shared hub with the biggest ecosystem and the heaviest security baggage, or a personal assistant with safer defaults and a better memory. Choose by the table above. Then run it inside Claworc, so the choice stays reversible and the safety story is the same either way. The quickstart gets a first instance running in a few minutes.
