Hermes Agent vs OpenClaw
We host both agents for our customers and run both ourselves.
Here is what actually differs, with sources, and how to switch.
The short answer
Both are open-source AI agents you can self-host on a small VPS, and both store memory as plain Markdown you can read and edit. OpenClaw is the bigger project, with more stars and a large plugin ecosystem. Hermes Agent is the one we find simpler to live with: messaging platforms are built in rather than installed as plugins, its memory is bounded and easy to audit, its runtime footprint is measured in hundreds of megabytes, and its 2026 security record is calmer. If you want a personal assistant that just runs, start with Hermes. If you need OpenClaw’s plugin breadth or its Node-based extension ecosystem, it remains a capable choice.
Side by side
Figures from the GitHub API and official documentation, checked July 2026.
| Hermes Agent | OpenClaw | |
|---|---|---|
| Built by | Nous Research | OpenClaw community (launched as Clawdbot, then Moltbot) |
| GitHub community | About 214k stars, 1,700+ contributors | About 383k stars, 2,600+ contributors — the larger project |
| Runtime | Python. The installer bundles Python, Node.js, and helper tools in one step. | TypeScript on Node.js (v22.19+ or v24 recommended), runs as a daemon service. |
| Messaging platforms | 24+ built into one gateway: Telegram, WhatsApp, Discord, Slack, Signal, iMessage, Matrix, Teams, Google Chat, email, and more. | 3 in the core (Telegram, iMessage, WebChat); roughly 20 more installed as plugins. |
| Memory design | Two bounded Markdown files plus SQLite full-text search, and portable learned skills. Small enough to read in one sitting. | Workspace Markdown with daily logs plus an SQLite index. Transparent too, but grows without built-in caps. |
| Typical RAM (cloud models) | Roughly 200 to 350 MB for the CLI, 400 to 950 MB with the gateway, per community measurements. | Guides cite 1 to 2 GB as the floor and recommend 2 to 4 GB with several channels. |
| Install | One command, then a setup wizard. Dependencies are fetched automatically. | One command, then an onboarding wizard and daemon setup. Channels add plugin installs. |
| Security record (2026) | One low-severity CVE published; an independent audit flagged permissive defaults worth tightening (approvals, sandboxing). | Several critical CVEs early in the year, including a one-click remote code execution, and researchers found about 1,800 exposed instances. Patched since, with improved hardening docs. |
| Release style | Weekly versioned releases; one-command update that preserves memory and config. | Date-based releases with frequent betas across a very large monorepo. |

Where each one wins
Pick Hermes Agent if you want
- The lightest day-to-day operation: fewer moving parts, channels built in, no plugin maintenance.
- A memory you can actually audit: two small files you can read, not an unbounded archive.
- A small server bill: it runs happily on a 2 GB VPS.
- Updates that do not eat your weekend: one command, memory preserved.
Pick OpenClaw if you want
- The biggest ecosystem: the most-starred agent on GitHub, with plugins for almost everything.
- Node-native extensibility, if TypeScript is your home turf.
- The largest pool of third-party guides, videos, and community answers.
- Exotic channels the Hermes gateway does not cover yet.
What we see hosting both
Virtua.Cloud offers one-command installs for both agents, so we watch real users set up each one every week. The pattern is consistent: OpenClaw questions that reach our support are mostly about plugin configuration and things that stopped working after an update. Hermes questions are mostly about messaging platform API keys, which is one-time setup rather than maintenance.
That gap is what "simpler to operate" means in practice. It is not about the install, which is one command for both. It is about month two and month three: how often you have to intervene to keep the agent doing its job.
Our own agents run on Hermes. We keep OpenClaw images current because plenty of people rightly choose it for its ecosystem, and it deserves a properly secured home when they do.
Switching from OpenClaw: an afternoon, not a weekend
Both agents keep their memory in plain Markdown, which makes moving between them refreshingly boring.
Back up your OpenClaw workspace
Your agent's memory and daily logs live in the workspace folder. Copy it somewhere safe before touching anything.
scp -r root@your.old.server:~/.openclaw/workspace ./openclaw-backup Deploy a fresh VPS and install Hermes Agent
A clean 2 GB server keeps the migration reversible: your OpenClaw box stays untouched until you are happy.
curl -fsSL https://virtua.sh/i/hermes-ssh | bash Carry the memory over
Open your old MEMORY.md, then tell Hermes the facts and preferences you want it to keep. It stores them with its memory tool, in its own bounded format. Most people are surprised how little of the old archive they actually need.
Reconnect your channels and run both for a week
Point your Telegram, Discord, or WhatsApp credentials at Hermes with the setup wizard. Keep the old server running in parallel for a few days, then power it down once nothing misses it.
