Hermes Agent vs OpenClaw: The Open-Source Agent Race Just Flipped
OpenClaw was the open-source agent of the moment in January. By late May, Nous Research's Hermes Agent has taken the top spot on OpenRouter. How to think about which one to install, and where each still wins.
In January, OpenClaw was the open-source agent of the moment. By late May, Nous Research's Hermes Agent has taken the top spot on OpenRouter and crossed 140,000 GitHub stars in under three months. That's not a tied race anymore. But OpenClaw isn't dead, and they're solving different problems.
Here's how to think about which one to actually install this weekend.
Hermes is built around memory. OpenClaw is built around control.
This is the cleanest way to split them.
Hermes Agent's pitch is "the agent that grows with you." Persistent memory across every session, plus a skills system: when Hermes works out how to solve a problem, it writes itself a skill document and files it. Next time, it knows. That document is portable too — Nous made it compatible with the agentskills.io open standard, so you can share skills across instances.
OpenClaw's pitch is "your own personal AI assistant. Any OS. Any platform." It ships with 100+ built-in skills out of the box, optimized for actually doing things on your machine: read and write files, run shell commands, browse websites, send emails, hit APIs. It's a digital worker, not a friend that remembers your birthday.
If you mostly want an agent that runs jobs, OpenClaw is more useful on day one. If you want an agent that gets meaningfully better the longer you live with it, Hermes is the one.
The integration story is different
Hermes connects through messaging platforms. One gateway process, and you can talk to it from Telegram, Discord, Slack, WhatsApp, Signal, or your terminal. The mental model is: there's an agent, and you talk to it from wherever you happen to be.
OpenClaw is more system-level. It plugs LLMs into local software through its skills and plugin ecosystem. The mental model is: there's a worker on your machine that can touch anything you let it touch.
This matters for how you use them. Hermes feels like a colleague you message. OpenClaw feels like a script you delegate to.
The security picture is not the same
On security: OpenClaw has had a rough quarter. A remote code execution flaw, hundreds of malicious third-party extensions caught in the wild, and warnings from both Palo Alto Networks and Cisco that the broad system access makes it a high-value target. None of that means OpenClaw is unsafe to run, but it means you need to actually think about permission control, sandbox it where you can, and audit any extension before you install it.
Hermes is younger and has had less time to be tested in the wild. That cuts both ways: fewer known issues, but also less battle-testing. If you're putting an agent on a machine that touches anything sensitive, Hermes's smaller attack surface (fewer extensions, fewer integration points) is currently the safer bet. Revisit in six months.
Install effort
Hermes: a single curl command on Linux, macOS, or WSL2. No prerequisites — it installs the dependencies for you. This is the smoothest install of any agent I've run this year.
OpenClaw: also one-command, but the configuration story is heavier because you'll want to tune permissions before you let it loose. Plan on an hour, not five minutes, before you actually trust it with real work.
Which one I'd pick today
If you're a developer and you want an agent you'll use daily for the next year, install Hermes. The memory and skills system pays off compound interest the longer you run it, and the safer default permission model means you spend less time auditing.
If you want a programmable worker to automate a specific workflow today — clean up a Downloads folder, monitor a feed and post to Slack, batch-rename a thousand files — OpenClaw is the right tool. It's been doing this longer and the skill library is bigger.
If you're not sure which describes you, install both. They don't conflict. Hermes for the long-running thing you talk to, OpenClaw for the workflow you fire and forget.
What this means for the rest of 2026
The Steinberger move to OpenAI in February, with OpenClaw transitioning to non-profit foundation stewardship, was the signal that the open-source agent race wasn't going to be a one-horse story. Hermes filling the gap this quickly is the second half of that signal.
Two months from now, I expect to be running both, and writing about whatever displaces them.
