The biggest question in the AI agent world right now is which agent is actually better — Hermes Agent or OpenClaw. After a month of testing both on the same tasks, the answer isn't what most people expect: they are not even the same kind of tool.
The best way to understand why is to look at how each one was actually built.
Opposite origins, opposite architectures
OpenClaw exists because someone wanted their AI to respond directly inside WhatsApp. They needed a bridge between an AI model and a messaging platform, so they built one — and that bridge became the entire product. That foundation still drives how everything works today.
Everything in OpenClaw flows through one central process: the Gateway. The Gateway handles channel routing, session management, tool dispatch, and events. The product is built around connecting your AI to as many platforms as possible.
Hermes Agent started from the opposite direction. NousResearch built it as a personal AI agent first, and the messaging integrations came after. The core of Hermes is not the gateway — it is the learning loop, where the agent creates its own skills from the work you give it and improves those skills over time.
OpenClaw: gateway first, agent lives inside it. Hermes: agent first, messaging is one way to reach it.
That distinction sounds subtle. It changes everything about how you use them.
- OpenClaw is built for people who want to control every behaviour explicitly
- Hermes is built for people who want the agent to learn and adapt on its own
The numbers
| OpenClaw | Hermes Agent | |
|---|---|---|
| GitHub stars | 370,000+ | 100,000+ (hit 100K in first 7 weeks) |
| Skill marketplace | ClawHub — 40,000+ community skills | Growing, smaller, newer |
| Messaging platforms | 50+ (WhatsApp, Telegram, Discord, Slack, iMessage, Matrix, WeChat, LINE, Signal, Google Chat, Email, browser) | 20+ (Telegram, Discord, Slack, WhatsApp, Signal, and others) |
| Self-generating skills | ❌ | ✅ |
| Multi-agent routing | ✅ | ❌ |
Infrastructure: both need a server
Both tools run on a persistent server. Both connect to Telegram and other messaging platforms. Both need an AI model provider (OpenRouter works for both). Neither works as a phone-only app — the Gateway/agent must run somewhere 24/7.
The phone apps for OpenClaw (iOS and Android) are nodes that connect to the server, not replacements for it. If your server sleeps, the phone disconnects.
Options for the server: your always-on Windows laptop + Cloudflare Tunnel, a home server, or a VPS (~$9/month on Hetzner or Hostinger).
Where OpenClaw is clearly stronger
1. Platform coverage — 50+ messaging integrations vs Hermes's 20+. If you need iMessage, Matrix, WeChat, LINE, Google Chat, or Email alongside the usual suspects, OpenClaw is the only option. Hermes covers the popular platforms but nothing close to 50.
2. Multi-agent routing — OpenClaw lets you run different agent personalities on different channels, contacts, or groups simultaneously. A casual agent for personal DMs, a professional agent for work Slack, a community manager for Discord — all through the same gateway. Hermes does not do this. It is one agent with one persistent identity.
3. Ecosystem — ClawHub has 40,000+ community-built skills covering e-commerce automation, customer support triage, content scheduling, and more. If someone has already built the workflow you need, you install and move on. Hermes's skill library is growing but significantly smaller on day one.
4. Explicit control — OpenClaw's configuration is entirely transparent.
soul.md defines the agent's identity. memory.md stores persistent context.
tools.md controls what the agent can access. Every behaviour is a file you
wrote, can read, and can edit. Nothing happens that you didn't configure.
Where Hermes Agent is clearly stronger
1. Self-improving learning loop — the defining feature, and nothing else in open-source AI agents has it right now.
When Hermes finishes a complex task, it pauses, looks back at the steps it took, and if it found a good approach, it writes a reusable skill file and saves it. The next time it encounters a similar problem, it searches its own skill library first before solving from scratch.
NousResearch's internal testing: agents with 20+ self-created skills complete similar tasks 40% faster than a fresh instance. A research task that took 15 minutes of back-and-forth on day one takes a single message by week three.
The skill library also curates itself: an autonomous curator runs on a 7-day cycle, consolidates overlapping skills, and removes anything you stopped using. The library stays useful without manual maintenance.
2. Cross-session recall — Hermes has full-text search across all past conversations. Ask it to find something you discussed 3 weeks ago and it pulls the exact conversation. OpenClaw has vector search over memory files, but Hermes's cross-session recall is noticeably better in practice.
3. Development pace — Hermes went from v0.1 to v0.8 in 2 months with 209 pull requests. Browser integration, remote backends, and the autonomous curator all shipped in that window. OpenClaw cannot match this pace right now.
4. Less manual configuration — with OpenClaw you write every rule, every personality detail, every tool permission by hand. With Hermes, you interact naturally and it learns your preferences through the memory system and self-generated skills. Less setup overhead.
