OpenClaw System Requirements: What Hardware and Software You Need

ByL.B. Kaelin

You’re about to install OpenClaw, but you’re staring at a blank terminal. You don’t know if your laptop is powerful enough, or if you need to buy new hardware. You’re worried about wasting a weekend on setup only to hit a cryptic error because your OS is wrong.

Getting the openclaw requirements | openclaw system requirements, openclaw specs wrong means frustration, not function. Your agent won’t run, or it will run so slowly it’s useless. This isn’t about checking boxes. It’s about making sure your first experience is “it works,” not “why is it broken?”

You care about this right now because you want to start building, not debugging. A correct setup is the foundation. Skip this, and everything you try to build on top will be shaky.

After this, you’ll know exactly what you need. You’ll be able to look at your current machine, give a yes or no, and know what to upgrade if it’s a no. You’ll have a clear list for your operating system, memory, storage, and the one piece of software that everything depends on.

Let’s get your system ready so your Claw can get to work.

What You Need Before Starting

Think of these as the foundation for your house. If the foundation is wrong, the house falls down. If these are wrong, OpenClaw won’t run, or it will be so slow you can’t use it.

  • A 64-bit Operating System: OpenClaw is built for modern systems. 32-bit systems are like trying to fit a truckload of furniture into a compact car. It won’t work. You need a 64-bit version of Linux, macOS, or Windows.
  • Docker and Docker Compose: This is the single most important piece. OpenClaw and all its services (like the database) run in isolated containers. Docker is the platform that manages these containers. It’s like a standardized shipping container system for software. Without it, you have to manually install and configure a dozen different programs. With it, you run one command and everything is set up correctly.
  • At least 8GB of RAM (16GB Recommended): Your Claw agent, its language model, and supporting services all need memory. 8GB is the absolute minimum. With 8GB, your system will be slow and you might run out of memory if you do anything else. 16GB gives your agent room to think and lets you use your computer normally. If you’re serious, start with 16GB.
  • At least 20GB of Free Storage: Docker images, language models, and the database need space. 20GB is for a basic setup. If you plan to use larger models or store a lot of agent history, you’ll need more. Running out of disk space during setup is a common, frustrating error.
  • A Multi-core CPU: Your agent does many things at once. A modern multi-core processor (Intel i5/Ryzen 5 or better from the last 5 years) is fine. Older dual-core processors will struggle. This is about speed, not just function.
  • Git: You’ll use Git to download the OpenClaw source code. It’s the standard tool for getting code from the internet.

Setting Up Your Environment

This is where you turn your computer into a Claw-ready machine. We’ll install the one non-negotiable dependency: Docker. Everything else happens inside Docker containers, which is why this step is so critical.

If you already have Docker and Docker Compose installed and running, you can skip to the next section. To check, open a terminal and run docker --version and docker compose version. If both commands return version numbers, you’re good.

Installing Docker and Docker Compose

Docker is the platform. Docker Compose is the tool that reads the OpenClaw configuration file and starts all the necessary services in the right order. You need both.

The installation is different for each operating system. Follow the instructions for your OS. This is the one part you’ll likely do manually. Once Docker is running, your Claw can handle almost everything else.

For Debian/Ubuntu Linux

The official Docker repository is the most reliable method. These commands add that repository to your system’s software sources and install the packages.

# Update your existing package list
sudo apt-get update

# Install packages to allow apt to use a repository over HTTPS
sudo apt-get install ca-certificates curl

# Add Docker's official GPG key
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the Docker repository to Apt sources
echo \
 "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
 $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
 sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# Update the package database again with the new repo
sudo apt-get update

# Install Docker Engine, CLI, Containerd, and Docker Compose
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# Verify the installation
docker --version
docker compose version

You should see version numbers for both Docker and Docker Compose. The final step is to add your user to the `docker` group so you don’t need to use `sudo` for every Docker command.

# Add your user to the docker group
sudo usermod -aG docker $USER

# Apply the new group membership (you will need to log out and back in, or run this)
newgrp docker

After running `newgrp docker`, try `docker ps` in the same terminal. If it returns without an error, your setup is complete.

For macOS

The easiest way is to use Docker Desktop. It bundles Docker Engine, Docker CLI, and Docker Compose into one application.

  1. Download Docker Desktop for Apple Silicon or Intel from the official Docker website.
  2. Double-click the `.dmg` file and drag the Docker icon to your Applications folder.
  3. Open Docker Desktop from your Applications folder. Follow the on-screen prompts to complete the installation. This may require entering your password.
  4. Once Docker Desktop is running, you’ll see the whale icon in your menu bar. Open your terminal and run docker --version and docker compose version to confirm.

Docker Desktop manages permissions for you, so you won’t need to add your user to a group.

For Windows

You must use Windows Subsystem for Linux 2 (WSL2). Docker Desktop for Windows integrates with WSL2. This lets you run a Linux environment where OpenClaw operates natively.

  1. Enable WSL2. Open PowerShell as Administrator and run: 
    wsl --install

    This command installs WSL2 and a default Linux distribution (usually Ubuntu). Restart your computer when prompted.

  2. Download and install Docker Desktop for Windows.
  3. Open Docker Desktop. Go to Settings > Resources > WSL Integration. Enable integration with your installed WSL2 distribution (e.g., Ubuntu).
  4. Open your WSL2 terminal (e.g., Ubuntu from the Start menu). Run docker --version and docker compose version to confirm.

All your OpenClaw work will happen inside this WSL2 terminal. Do not use the standard Windows Command Prompt or PowerShell for OpenClaw commands.

Verifying Your Setup

Now, let’s make sure Docker is working correctly. This is a quick health check. Once your Claw is running, you can give it this exact task to run for you in the future.

Open your terminal (or WSL2 terminal on Windows) and run this check.

# This command starts a test container, prints a message, and then stops.
docker run hello-world

You should see a message that says “Hello from Docker!” along with explanation text. If you see this, your Docker installation is working. If you get a permission error, ensure you’ve logged out and back in after adding yourself to the `docker` group (Linux) or that Docker Desktop is running (macOS/Windows).

You have the foundation. Your system is now ready for OpenClaw.
