WHAT IS OPENCLAW

OpenClaw is a self-hosted AI assistant that connects to your messaging platforms and runs 24/7 on your own machine. It started as Clawdbot, got rebranded to OpenClaw in early 2026, and has since become the most popular open-source AI agent in the world with over 345,000 GitHub stars.

You install it on your computer or a server, connect it to Telegram, WhatsApp, Discord, Slack, or any of its 24+ supported messaging platforms, and it becomes an always-on AI assistant you can talk to from your phone. It has a skill marketplace called ClawHub with over 13,000 community-built skills that you can install to make your agent more capable.

How to install OpenClaw:

The fastest way is npm. Open your terminal and run:

npm install -g openclaw

Then run:

openclaw init

This walks you through a setup wizard where you choose your AI provider (OpenAI, Anthropic, or a local model through Ollama), connect your messaging platform, and configure your first agent. The whole setup takes about 30 minutes.

You can also install via Docker:

docker pull openclaw/openclaw:latest

Or on Windows through WSL2 which gives you a Linux environment. Native Windows support exists but WSL2 is the recommended path.

Requirements: Node.js v22 or higher, Git, and an API key for your model of choice (or Ollama for local models).

WHAT IS HERMES AGENT

Hermes Agent is an open-source autonomous AI agent built by Nous Research, the lab behind the Hermes and Nomos language models. It launched in February 2026 and has been growing fast because of one feature no other agent has: a built-in learning loop where the agent creates skills from experience and gets better over time without you programming anything.

Hermes runs on your machine, remembers what it learns across sessions, and supports Linux, macOS, and Windows (native PowerShell installer or WSL2). It is MIT licensed and completely free. All your data stays local with no telemetry and no cloud lock-in.

Official website: hermes-agent.org GitHub: github.com/NousResearch/hermes-agent Documentation: hermes-agent.nousresearch.com/docs Quickstart: hermes-agent.nousresearch.com/docs/getting-started/quickstart Skills Hub: agentskills.io

How to install Hermes Agent:

One command on macOS or Linux:

curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash

This installs everything automatically including Python, Node.js, ripgrep, ffmpeg, the repo, the virtual environment, and the global hermes command. No sudo needed. The only prerequisite is Git.

On Windows (native, no WSL required):

Open PowerShell and run:

iex (irm https://hermes-agent.nousresearch.com/install.ps1)

Or download the Hermes Desktop installer from hermes-agent.org for both the GUI and CLI.

After installing, run:

hermes setup --portal

This logs you into Nous Portal with one OAuth which gives you access to 300+ models plus web search, image generation, text-to-speech, and a cloud browser all through one subscription. Or you can use your own API keys for OpenAI, Anthropic, OpenRouter, or any OpenAI-compatible endpoint.

Hermes can run on almost anything. A $5 VPS with 1 CPU and 1GB RAM handles it fine when using cloud APIs. It can also run on a GPU cluster, serverless infrastructure, or your laptop.

THE 3 THINGS HERMES DOES BETTER

1. Self-Learning Loop

This is the single biggest difference and the main reason people are switching.

OpenClaw skills are static. You write a skill or install one from ClawHub and it works the exact same way every time forever. It never adapts. It never improves on its own.

Hermes skills are self-evolving. Every time Hermes completes a task it analyzes what it did and saves the workflow as a reusable skill automatically. Run the same type of task 50 times and by the end it is genuinely faster and better because it learned from every single run without you telling it to.

On top of that Hermes has a built-in curator that runs every 7 days in the background. It reviews which skills are being used and prunes the ones that are not. So instead of getting bloated over time like OpenClaw, Hermes stays lean and fast the longer you run it.

To configure the curator: hermes config set curator.interval 7d (default is 7 days, you can set it to nightly or any interval you want).

1. Checkpoints and Rollback

Before Hermes touches any of your files it takes a full snapshot of your working directory. If something goes wrong you type /rollback and everything goes back to exactly how it was before the agent made changes. One command. Full restore.

OpenClaw does not have this. If an agent edits the wrong file or deletes something you have to manually undo everything yourself.

1. Reliability and Security

OpenClaw has had serious stability and security issues in 2026. Every update tends to break existing setups and users report spending 30 minutes after each update fixing things. On the security side, researchers found 9 CVEs in 4 days earlier this year and discovered that 12% of skills on ClawHub were actually malware. Over 135,000 OpenClaw instances were found exposed on Shodan.

Hermes has zero reported CVEs. It has namespace isolation, container hardening, and credential rotation built in. Updates are less frequent but focused and nothing breaks when you update.

THE 4 THINGS OPENCLAW STILL DOES BETTER

1. Bigger Skill Ecosystem

ClawHub has over 13,000 community-built skills compared to Hermes' smaller Skills Hub at agentskills.io. If you need a skill for a very specific integration or workflow there is a much higher chance someone already built it for OpenClaw.

1. More Messaging Integrations

OpenClaw supports 24+ messaging platforms out of the box including WhatsApp, Telegram, Discord, Slack, iMessage, SMS, and many more. Hermes supports Telegram, Discord, Slack, and WhatsApp with more being added.

1. Easier Initial Setup

Most people report getting OpenClaw running in about 30 minutes with the setup wizard. Hermes setup is faster now with the one-line installer but configuring multiple agents, skills, and workflows can take 2 to 4 hours for a full production setup.

1. Larger Community

OpenClaw has over 345,000 GitHub stars and a massive community creating tutorials, guides, and skills. If you get stuck there are more resources, more YouTube videos, and more people who can help. The Discord community is very active.

WHICH MODELS TO USE

For OpenClaw: Claude Sonnet 4.6 is the community standard for daily use. Covers 90% of workflows. Claude Opus 4.6 for complex multi-step reasoning. Kimi K2.5 is currently the number one community vote winner on the OpenClaw leaderboard. MiniMax M2.7 for budget-conscious setups with generous quotas.

For Hermes: Claude Sonnet 4.6 is the top recommendation because tool calling reliability is the most important factor for an executor agent. DeepSeek V4 at $0.30/$0.50 per million tokens is the budget option with 90% cache discounts. MiniMax M2.7 is optimized specifically for Hermes through a collaboration with Nous Research. Any model through Nous Portal (300+ models with one subscription) or OpenRouter (200+ models).

To switch models in Hermes at any time: hermes model (interactive selector) or hermes chat --model "anthropic/claude-sonnet-4" for a specific session.

To switch models in OpenClaw: update the model field in your config file or use the dashboard model catalog.

WHO SHOULD USE WHICH

Use Hermes if: Reliability matters more to you than having the biggest skill library. You are running agents on client projects where broken updates or security issues are unacceptable. You want agents that get better over time without you doing anything. You want rollback protection when agents are working on important files. You are comfortable with a slightly longer initial setup for a more stable long-term experience.

Use OpenClaw if: You need the largest possible ecosystem of pre-built skills. Your workflow requires connecting to a specific messaging platform or service that Hermes does not support yet. You want the fastest possible setup with the most community resources available. You are building something where the massive ecosystem of tutorials and community support matters more than self-learning capabilities.

Use both together if: You want the best of both worlds. The supervisor-builder workflow is the most popular way to run them together. OpenClaw acts as the supervisor handling planning, scheduling, and multi-platform communication. Hermes acts as the builder handling task execution and self-improvement. OpenClaw delegates work to Hermes. Hermes executes and learns. OpenClaw reviews the results. You get OpenClaw's superior orchestration and integrations combined with Hermes' self-learning and reliability.

RUNNING THEM TOGETHER: THE SUPERVISOR-BUILDER PATTERN

Step 1: Install both on the same machine or server.

Step 2: Connect OpenClaw to all your messaging platforms (Telegram, Slack, WhatsApp, etc). This is how you communicate with your agent team.

Step 3: Connect Hermes to OpenClaw as the execution layer. Tell OpenClaw to route all execution tasks to Hermes and keep planning and delegation for itself.

Step 4: Give them a workflow. Start with a daily briefing: check inbox, summarize what needs a response, pull calendar events, send the briefing to Telegram. OpenClaw handles the orchestration. Hermes handles the execution and saves the workflow as a reusable skill.

Step 5: Stack more workflows. Content monitoring. Client follow-ups. Research. Each one runs in parallel. Each one self-improves through Hermes' learning loop.

The result is an agent team where OpenClaw handles what it is best at (orchestration, multi-platform communication, large skill ecosystem) and Hermes handles what it is best at (reliable execution, self-learning, safe file operations with rollback). Together they cover each other's weaknesses.

COST COMPARISON

OpenClaw: Free and open source. No licensing cost. API costs depend on your model choice ($3-15 per million tokens for Claude Sonnet/Opus). Can run locally with Ollama for zero API cost but lower quality. VPS hosting: $5-20/month depending on usage.

Hermes: Free and open source. MIT license. API costs same as OpenClaw since it uses the same models. Nous Portal subscription covers 300+ models plus web search, image gen, TTS, and browser. Can run on a $5 VPS with 1 CPU and 1GB RAM using cloud APIs. Serverless deployment possible through Modal for near-zero idle cost.

THE BOTTOM LINE

Both tools are powerful and both are free. OpenClaw has the bigger ecosystem, more integrations, and a massive community. Hermes has the self-learning loop, better security, and more reliable updates.

If you are just starting with AI agents and you want the easiest path with the most support, OpenClaw is the safer bet. If you want an agent that genuinely improves over time and you value stability over ecosystem size, start with Hermes. If you want the most capable setup possible, run both together in the supervisor-builder pattern and let each tool do what it does best.
