OpenClaw vs Hermes Agent (2026)

At a glance

Star counts and versions come from GitHub on our daily refresh (last 17 Oct 2026). OpenClaw also records about 3,964,886 npm downloads a week; we don't track a comparable download count for Hermes, so it's unknown here.

What they're like to use

Both live in the chat apps you already use, so you message your agent like a person. OpenClaw leans into everyday life admin: inbox, email, calendar, flight check-in, browsing and filling in forms1. Hermes leans into getting better over time: it keeps memory across conversations, writes its own skills from what it learns, runs scheduled tasks you describe in plain language, and spins up isolated subagents for parallel work2.

Neither is a sign-up product. You'll install it, connect a model provider and pay for that model's usage yourself. Hermes offers optional Nous Portal tiers (Free, Plus, Super, Ultra) for model access, but we couldn't verify their prices2.

Security: two very different stories

OpenClaw: lots of fixes, good defaults, your responsibility

OpenClaw publishes vulnerabilities as GitHub advisories; we counted 722 published between 31 Jan and 11 Sep 2026, 14 of them critical4. Its policy treats one Gateway as one trusted boundary, "not a hostile multi-tenant security boundary"9, and it documents a hardened baseline: local-only Gateway with token auth, a messaging-only tool profile, workspace-only file access and shell execution denied or always-ask3. Our Is OpenClaw safe? guide covers this in detail.

Hermes: an honest threat model

Hermes's SECURITY.md is refreshingly direct: "The only security boundary against an adversarial LLM is the operating system."5 Its approval gate, redaction and allowlists are described as heuristics, not guarantees5. Two details matter in practice:

• The default terminal backend runs on your host, and choosing a sandboxed terminal backend confines only shell and file tools, not code execution, MCP servers, plugins or skills5.
• For untrusted input (web pages, email, several users), the supported setup is to wrap the whole process, using the Docker image or Compose, or NVIDIA OpenShell5.

On the plus side, API keys and gateway tokens are stripped from subprocess environments by default5. There's no bug bounty5. GitHub returned no published advisories for the repository8; that could mean fewer reported problems or less formal disclosure, and we can't tell which.

Which should you choose?

• You want the widest choice of chat apps and the biggest community: OpenClaw16.
• You want the agent to learn routines and run scheduled briefings: Hermes, with auto-generated skills and natural-language scheduling2.
• You'll feed it untrusted email or web content: either, but in a container. Hermes documents whole-process Docker wrapping as the supported posture5; OpenClaw documents a hardened baseline and an audit command39.
• Several people will share it: neither is built as a multi-tenant boundary95. Run separate instances per person.
• You don't want to run servers: neither. Look at hosted agents in the buyer's guide; prices are on /pricing.

Setup checklist for either

1. Run it on a dedicated machine or VM, not your main laptop.
2. Use a separate phone number or account for chat channels.
3. Start with read-only tools; add sending and shell access one at a time.
4. Keep model API keys in the agent's secret store, never in chat.
5. Subscribe to release notifications and update weekly.
