Deploy OpenClaw on AWS or Hetzner Securely with Pulumi and Tailscale

Engin Diri — Mon, 26 Jan 2026 00:00:00 +0000

Update (January 2026): The lobster has molted into its final form! From Clawdbot to Moltbot to OpenClaw. With 100k+ GitHub stars and 2M visitors in a week, the project finally has a name that’ll stick. The CLI command is now openclaw and the new handle is @openclaw. Same mission: AI that actually does things. Your assistant. Your machine. Your rules. See the official getting started guide for updated installation instructions.

Update (April 2026): Refreshed for OpenClaw 2026.4.27. Upstream now recommends Node 24, but the cloud-init script in this post still installs Node 22 — both work. If you’d like Node 24, change the nvm install 22 lines to nvm install 24.

The short version: Deploy OpenClaw to AWS or Hetzner with a Pulumi TypeScript program that provisions the VM, installs Docker, Node, and OpenClaw, then joins the instance to your Tailscale network so the gateway and browser ports stay private. One pulumi up to deploy, one pulumi destroy to tear down. Total cost: about $33/month on AWS or $7/month on Hetzner.

OpenClaw is everywhere right now. The open-source AI assistant gained 9,000 GitHub stars in a single day, received public praise from former Tesla AI head Andrej Karpathy, and has sparked a global run on Mac Minis as developers scramble to give this “lobster assistant” a home. Users are calling it “Jarvis living in a hard drive” and “Claude with hands”—the personal AI assistant that Siri promised but never delivered.

The Mac Mini craze is real: people are buying dedicated hardware just to run OpenClaw, with some enthusiasts purchasing 40 Mac Minis at once. Even Logan Kilpatrick from Google DeepMind couldn’t resist ordering one. But here’s the thing: you don’t actually need a Mac Mini. OpenClaw runs anywhere: on a VPS, in the cloud, or on that old laptop gathering dust.

With all this hype, I had to try it myself. But instead of clicking through the AWS console or running manual commands on a VPS, I wanted to do it right from the start: infrastructure as code with Pulumi. Why? Because when I inevitably want to tear it down, spin up a new instance, or deploy to a different region, I don’t want to remember which buttons I clicked three weeks ago. I want a single pulumi up command.

Dan got the assignment right:

In this post, I’ll show you how to deploy OpenClaw to AWS or Hetzner Cloud (if you want European data residency or just want to spend less). We’ll use Pulumi to define the infrastructure and Tailscale to keep your AI assistant off the public internet.

What is OpenClaw?

OpenClaw is an open-source AI assistant created by Peter Steinberger that runs on your own infrastructure. It connects to WhatsApp, Slack, Discord, Google Chat, Signal, and iMessage. It can control browsers, generate videos and images, clone your voice for voice notes, and run scheduled tasks via cron. There’s a skills system for extending functionality, and you can run it on pretty much anything: Mac Mini, Raspberry Pi, VPS, laptop, or gaming PC.

The difference from cloud-hosted AI? OpenClaw runs on your server, not Anthropic’s. It’s available 24/7 across all your devices, can schedule automated tasks, and keeps your entire conversation history locally. Check the official OpenClaw documentation for the full feature list.

Prerequisites

Before getting started, ensure you have:

Pulumi CLI installed and configured
A Pulumi Cloud account
AWS account (for AWS deployment)
Hetzner Cloud account (for European deployment)
Anthropic API key
Node.js 22+ installed (Node 24 recommended; the cloud-init script in this post installs Node 22 inside the VM)
Tailscale account with HTTPS enabled (one-time setup in admin console)

This guide uses Anthropic’s API, but OpenClaw works with other providers too. Check the providers documentation if you’d rather use OpenAI, Google Gemini, or a local model via Ollama.

Understanding OpenClaw architecture

OpenClaw uses a gateway-centric architecture where a single daemon acts as the control plane for all messaging, tool execution, and client connections:

Component	Port	Description
Gateway	18789	WebSocket server handling channels, nodes, sessions, and hooks
Browser control	18791	Headless Chrome instance for web automation
Docker sandbox	-	Isolated container environment for running tools safely

The Gateway connects to messaging platforms (WhatsApp, Slack, Discord, etc.), the CLI, the web UI, and mobile apps. The Browser component lets OpenClaw open web pages, fill forms, scrape data, and download files. Docker sandboxing runs bash commands in isolated containers so your bot can execute code without risking your host system.

Setting up ESC for secrets management

Deploying OpenClaw means handling sensitive credentials: API keys, auth tokens, cloud provider secrets. You don’t want these hardcoded or scattered across environment variables. Pulumi ESC (Environments, Secrets, and Configuration) stores them securely and passes them directly to your Pulumi program — the same pattern Pulumi uses to eliminate long-lived CI secrets across 70+ repos.

Create a new ESC environment:

pulumi env init <your-org>/openclaw-secrets

Add your secrets to the environment:

values:
 anthropicApiKey:
 fn::secret: "sk-ant-xxxxx"
 tailscaleAuthKey:
 fn::secret: "tskey-auth-xxxxx"
 tailnetDnsName: "tailxxxxx.ts.net"
 hcloudToken:
 fn::secret: "your-hetzner-api-token"
 pulumiConfig:
 anthropicApiKey: ${anthropicApiKey}
 tailscaleAuthKey: ${tailscaleAuthKey}
 tailnetDnsName: ${tailnetDnsName}
 hcloud:token: ${hcloudToken}

To find your tailnet DNS name, go to the Tailscale admin console, look under the DNS section, and find your tailnet name (e.g., tailxxxxx.ts.net). This is the domain suffix used for all machines in your Tailscale network.

Then create a Pulumi.dev.yaml file in your project to reference the environment:

environment:
 - <your-org>/openclaw-secrets

This approach keeps your secrets out of your codebase and passes them directly to OpenClaw during automated onboarding. To prevent stack-level overrides of these values, see locking down ESC values with fn::final.

Securing with Tailscale

By default, deploying OpenClaw exposes SSH (port 22), the gateway (port 18789), and browser control (port 18791) to the public internet. This is convenient for testing but not ideal for production use.

Tailscale creates a secure mesh VPN that lets you access your OpenClaw instance without exposing unnecessary ports publicly. When you provide a Tailscale auth key, the Pulumi program:

Removes gateway and browser ports from public access
Keeps SSH as fallback for debugging if Tailscale setup fails
Installs Tailscale on the instance during provisioning (after other dependencies)
Enables Tailscale SSH so you can SSH via Tailscale without managing keys
Joins your tailnet automatically using the auth key

The Pulumi program installs Docker, Node.js, and OpenClaw first, then configures Tailscale last. This ensures that even if the Tailscale auth key is invalid or expired, you can still SSH in via the public IP to troubleshoot.

To generate a Tailscale auth key:

Go to Tailscale Admin Console
Click “Generate auth key”
Enable “Reusable” if you plan to redeploy
Copy the key and add it to your ESC environment

Deploying to AWS

Let’s walk through the complete AWS deployment. Create a new Pulumi project:

mkdir openclaw-aws && cd openclaw-aws
pulumi new typescript

Install the required dependencies:

npm install @pulumi/aws @pulumi/tls

Do not use t3.micro instances for OpenClaw. The 1 GB memory is insufficient for installation. Use t3.medium (4 GB) or t3.large (8 GB) instead.

The Pulumi program

Running OpenClaw on AWS means setting up a VPC, subnets, security groups, an EC2 instance, SSH keys, and a cloud-init script that installs everything. That’s a lot of clicking in the AWS console. The Pulumi program below defines all of it in code.

Replace the contents of index.ts with the following:

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
import * as tls from "@pulumi/tls";

const config = new pulumi.Config();

const instanceType = config.get("instanceType") ?? "t3.medium";
const anthropicApiKey = config.requireSecret("anthropicApiKey");
const model = config.get("model") ?? "anthropic/claude-sonnet-4";
const enableSandbox = config.getBoolean("enableSandbox") ?? true;
const gatewayPort = config.getNumber("gatewayPort") ?? 18789;
const browserPort = config.getNumber("browserPort") ?? 18791;

const tailscaleAuthKey = config.requireSecret("tailscaleAuthKey");
const tailnetDnsName = config.require("tailnetDnsName");

// Generate a random token for gateway authentication
const gatewayToken = new tls.PrivateKey("openclaw-gateway-token", {
 algorithm: "ED25519",
}).publicKeyOpenssh.apply(key => {
 // Create a deterministic token from the public key (take first 48 hex chars)
 const hash = require("crypto").createHash("sha256").update(key).digest("hex");
 return hash.substring(0, 48);
});

const sshKey = new tls.PrivateKey("openclaw-ssh-key", {
 algorithm: "ED25519",
});

const vpc = new aws.ec2.Vpc("openclaw-vpc", {
 cidrBlock: "10.0.0.0/16",

 },
 ],
 tags: { Name: "openclaw-rt" },
});

new aws.ec2.RouteTableAssociation("openclaw-rta", {
 subnetId: subnet.id,

});

const securityGroup = new aws.ec2.SecurityGroup("openclaw-sg", {

});

const keyPair = new aws.ec2.KeyPair("openclaw-keypair", {
 publicKey: sshKey.publicKeyOpenssh,
});

const ami = aws.ec2.getAmiOutput({
 owners: ["099720109477"],
 mostRecent: true,

Deploying to Hetzner

Hetzner Cloud is a solid choice if you need European data residency or want to spend less money. Spoiler: it’s a lot less money.

Hetzner has similar concepts to AWS but different names. EC2 instances become Servers. Security groups become Firewalls. Same idea, different provider. The resource types come from @pulumi/hcloud.

Create a new project for Hetzner:

mkdir openclaw-hetzner && cd openclaw-hetzner
pulumi new typescript

Install the Hetzner provider:

npm install @pulumi/hcloud @pulumi/tls

The default server type cax21 is an ARM-based (Ampere) instance with 4 vCPUs and 8 GB RAM. ARM instances cost less for the same compute. If you need x86 architecture, use ccx13 or similar CCX series instead.

The Hetzner Pulumi program

Replace index.ts with the following:

import * as pulumi from "@pulumi/pulumi";
import * as hcloud from "@pulumi/hcloud";
import * as tls from "@pulumi/tls";

const config = new pulumi.Config();

const serverType = config.get("serverType") ?? "cax21";
const location = config.get("location") ?? "fsn1";
const anthropicApiKey = config.requireSecret("anthropicApiKey");
const model = config.get("model") ?? "anthropic/claude-sonnet-4";
const enableSandbox = config.getBoolean("enableSandbox") ?? true;
const gatewayPort = config.getNumber("gatewayPort") ?? 18789;
const browserPort = config.getNumber("browserPort") ?? 18791;

const tailscaleAuthKey = config.requireSecret("tailscaleAuthKey");
const tailnetDnsName = config.require("tailnetDnsName");

// Generate a random token for gateway authentication
const gatewayToken = new tls.PrivateKey("openclaw-gateway-token", {
 algorithm: "ED25519",
}).publicKeyOpenssh.apply(key => {
 const hash = require("crypto").createHash("sha256").update(key).digest("hex");
 return hash.substring(0, 48);
});

const sshKey = new tls.PrivateKey("openclaw-ssh-key", {
 algorithm: "ED25519",
});

const hcloudSshKey = new hcloud.SshKey("openclaw-sshkey", {
 publicKey: sshKey.publicKeyOpenssh,
});

const firewallRules: hcloud.types.input.FirewallRule[] = [

Cost comparison

Before deploying, let’s compare the costs between AWS and Hetzner for running OpenClaw 24/7:

	AWS (t3.medium)	Hetzner (cax21)
vCPUs	2	4
Memory	4 GB	8 GB
Storage	30 GB gp3 (+$2.40/mo)	80 GB NVMe (included)
Traffic	Pay per GB	20 TB included
Architecture	x86 (Intel/AMD)	ARM (Ampere)
Hourly price	$0.0416	€0.0104 (~$0.011)
Monthly price	~$33 (with storage)	€6.49 (~$7)
Annual cost	~$396	~$84

Hetzner gives you double the vCPUs, double the RAM, at less than a quarter of the price. The trade-off? ARM architecture instead of x86. But OpenClaw doesn’t care - it’s just Node.js and Docker.

Prices are for on-demand instances as of January 2026. AWS prices are for us-east-1; Hetzner prices exclude VAT. Both include standard networking and storage. Check AWS EC2 pricing and Hetzner Cloud pricing for current rates.

Running the deployment

With your ESC environment configured in Pulumi.dev.yaml, deploy with:

pulumi up

After deployment completes, you’ll see outputs similar to:

Outputs:
 gatewayTokenOutput : "786c099cc8f8bf20dbebf40b8b51b75cf5cdab25..."
 privateKey : [secret]
 publicDns : "ec2-x-x-x-x.compute-1.amazonaws.com"
 publicIp : "x.x.x.x"
 tailscaleUrlWithToken: "https://ip-10-0-1-x.tailxxxxx.ts.net/?token=786c099..."

The tailscaleUrlWithToken output provides the complete URL with authentication token. Copy and paste it into your browser to access the OpenClaw web UI.

Output names vary slightly between providers: AWS uses publicIp and publicDns, while Hetzner uses ipv4Address. The Tailscale hostname is derived from the instance’s private IP (AWS) or server name (Hetzner).

Automated onboarding

The Pulumi program runs OpenClaw’s non-interactive onboarding during instance provisioning. It uses your Anthropic API key from ESC, binds the gateway to loopback with Tailscale Serve as the HTTPS proxy, generates a secure gateway token (exported in Pulumi outputs), installs the daemon as a systemd user service, and configures trustedProxies and controlUi.allowInsecureAuth to skip device pairing when accessed via Tailscale.

The cloud-init script runs openclaw onboard --non-interactive with all necessary flags, then configures the gateway for secure Tailscale access. Your instance is ready as soon as provisioning finishes.

Access the web UI

Please wait 3-5 minutes after pulumi up completes. The cloud-init script runs after the instance launches and needs time to install Docker, Node.js, OpenClaw, and Tailscale, then run the onboarding process and start the daemon. Periodically refresh the page until it loads. If the page still doesn’t load after 5 minutes, see Verify the deployment to troubleshoot.

The easiest way to access the OpenClaw web UI is to use the tailscaleUrlWithToken output from Pulumi:

# Get the full URL with token
pulumi stack output tailscaleUrlWithToken

Copy and paste this URL into your browser. The URL includes both the Tailscale MagicDNS hostname and the authentication token, so you can access the web UI directly.

Finding your tailnet DNS name: Go to the Tailscale admin console and look under the DNS section for your tailnet name (e.g., tailxxxxx.ts.net). You can also find your machines and their MagicDNS hostnames in the Machines tab.

Token-based authentication provides an additional layer of security on top of Tailscale’s network-level authentication. Only devices on your tailnet can reach the URL, and the token prevents unauthorized access if someone gains access to your tailnet.

From the web UI, you can connect messaging channels (WhatsApp, Discord, Slack), configure skills and integrations, and manage settings.

Verify the deployment (optional)

If you encounter issues accessing the web UI, you can SSH into your instance to troubleshoot:

# Check your Tailscale admin console for the new machine
ssh ubuntu@<tailscale-ip>

# Check OpenClaw gateway status
systemctl --user status openclaw-gateway

Test your assistant

Open the gateway dashboard using the tailscaleUrlWithToken output and use the built-in chat to test your assistant:

Your personal AI assistant is now running 24/7 on your own infrastructure, accessible securely through Tailscale.

Redeploy OpenClaw with one command

With your infrastructure defined in Pulumi, you can move OpenClaw to a new region, rebuild it, or tear it down with pulumi destroy, without remembering which console buttons you clicked.

Get started

Security considerations

When self-hosting an AI assistant, security matters. OpenClaw’s rapid adoption meant thousands of instances spun up in days, and not everyone locked them down. The community noticed:

The tweet isn’t exaggerating. A quick Shodan search shows exposed gateways on port 18789 with shell access, browser automation, and API keys up for grabs:

Don’t let your instance be one of them.

Concern	Without Tailscale	With Tailscale
SSH access	Public (port 22 open)	Public fallback + Tailscale SSH
Gateway access	Public (port 18789 open)	Private (Tailscale only)
Browser control	Public (port 18791 open)	Private (Tailscale only)
API keys in transit	Exposed if gateway accessed over HTTP	Protected by Tailscale encryption
Attack surface	3 open ports	1 open port (SSH fallback)

SSH remains accessible as a fallback even with Tailscale enabled. This allows you to troubleshoot if Tailscale fails to connect. Once you’ve confirmed Tailscale is working, you can manually remove the SSH ingress rule from your security group for maximum security.

My recommendations:

Always use Tailscale for production
Rotate your auth keys periodically
Use Pulumi ESC for secrets instead of hardcoding
Enable Tailscale SSH to avoid managing keys manually
Monitor your Tailscale admin console for unauthorized devices
Remove the SSH fallback after confirming Tailscale works if you want zero public ports

What’s next?

Now that OpenClaw is running, you can install skills (voice generation, video creation, browser automation), set up scheduled tasks with cron, invite colleagues to your tailnet for shared access, or connect additional channels like WhatsApp and Discord.

Conclusion

Deploying OpenClaw with infrastructure as code means you can reproduce your setup anytime, version control it, and tear it down with a single command. Adding Tailscale keeps it private - no exposed ports, no hoping you configured your firewall correctly at 2am.
