OpenClaw AI VPS Requirements: What You Need to Run It (2026)

You are about to spend real money on a server, and you would rather not guess. 

Buy too little and your agent freezes or crashes without warning. Buy too much, and you are paying monthly for headroom you will never use.

The  OpenClaw AI VPS requirements are simpler than most guides make them sound, once you know what actually drives the number. 

This guide gives you the exact specs for your situation, explains why each matters, and tells you what you need beyond the server itself.

Most people only need to answer one real question before choosing a plan: 

Will this agent stay text-only, or will it eventually browse the web and run multiple instances? 

That single decision determines almost everything else about what you should buy.

The Short Answer

For a single text-only agent, 2 vCPUs, 4 GB of RAM, and 20-40 GB of SSD storage are sufficient. 

Run Ubuntu 22.04 or 24.04 LTS, and ensure Node.js 22 or later is available. 

If you plan to use browser automation or run more than one agent, plan for at least 4 vCPUs and 8 GB of RAM instead.

That single paragraph covers most people’s actual question. 

The sections below explain why those numbers are what they are, so you can size up or down with confidence rather than guessing.

These figures assume a dedicated VPS running only OpenClaw AI, not a shared server handling other workloads. 

If your server already runs other applications, add these numbers on top rather than assuming they overlap.

Text-Only Agent: The Baseline Setup

If your agent lives on Telegram or WhatsApp, answers messages, and does not touch a browser, 2 vCPUs and 4 GB of RAM is a genuinely comfortable fit.

The OpenClaw gateway itself uses somewhere between 400 MB and 800 MB of memory at idle, leaving plenty of room for the operating system and normal message traffic.

Give this setup 20 GB of SSD storage rather than the bare minimum. 

Logs, session files, and memory data accumulate faster than people expect, and starting with double the minimum avoids a disk resize a few months in.

A budget VPS at this tier typically costs very little per month, and most providers can provision it in minutes. 

There is no reason to overspend here if a text-only agent is all you are planning to run.

Adding Browser Automation Changes Everything

Browser automation is one of OpenClaw’s best features and the single biggest reason people under-provision their servers.

Each browser session can use 2 to 4 GB of memory on its own, which is more than your entire baseline setup.

Once browser automation is enabled, set 4 vCPUs and 8 GB of RAM as your floor. 

A 4 GB server running the gateway plus one browser session is already close to full, and the moment a second session opens, the server starts swapping, and everything slows down or crashes without a clear error message.

Storage climbs too, since browser sessions leave behind cache files and downloaded content. 

Give a browser-enabled setup 40-80 GB of SSD storage so you don’t have to clean up disk space every few weeks.

Running More Than One Agent

If you plan to run two or more agents on the same server, budget 2 to 3 GB of RAM per agent rather than assuming they will share comfortably. 

Two agents fit reasonably on 8 GB. 

Cramming three or four onto that same 8 GB usually ends with one of them getting killed mid-task the moment the others are busy.

Storage needs to grow alongside agent count, too. 

Plan for 60 to 100 GB of SSD storage once you are running multiple agents, since each one keeps its own logs, sessions, and workspace files.

CPU matters here more than people expect, too. 

Each agent competes for processing time when messages arrive at the same moment, so 4 or more vCPUs keep response times steady rather than letting agents queue up behind each other.

Software You Will Need Alongside the Hardware

The hardware specs only get you halfway there.

OpenClaw AI requires Node.js version 22 or higher, and most people also install Docker to keep the agent isolated and allow clean restarts.

Ubuntu 22.04 or 24.04 LTS is the safest operating system choice, mainly because it is what most OpenClaw documentation and community troubleshooting assume.

None of this is difficult to set up, and a one-click hosting option handles it all automatically if you would rather skip the command line entirely.

If you do want to install it yourself, the process is a handful of straightforward steps:

• Update the server
•  Install Node.js
• Pull OpenClaw
• Add your configuration
• Set it to start automatically. 

It is approachable even if you have never managed a server before.

Whichever path you choose, the same underlying software stack applies. 

A one-click setup simply runs those same steps in the background, rather than asking you to type each command yourself.

What You Need Besides the Server Itself

A properly specified VPS is only one piece of the puzzle.

You will also need an active API key from an AI provider such as OpenAI, Anthropic, or Google Gemini, since the server hosts the agent logic while the model itself runs elsewhere.

You will also need an account on whichever messaging platform you plan to use. 

Telegram is the simplest starting point and usually takes a couple of minutes to connect. 

WhatsApp works too, but it involves a slightly longer setup through Meta’s developer tools.

Neither of these costs anything to set up on its own, but it is worth having both ready before you provision your server. 

Sitting on a fully configured VPS without an API key yet is a common and easily avoidable delay.

A Quick Word on Security

OpenClaw AI needs meaningful access to your server to do its job, so it is worth getting the basics right from day one.

Keep the gateway bound to your own machine rather than exposing it publicly, and use a secure connection method if you need to reach it remotely.

This is one area where a managed or one-click setup genuinely earns its keep, since the secure defaults are already in place before you ever log in.

If you are setting things up manually, this is worth double-checking rather than assuming the defaults are safe.

A quick firewall check and a loopback-only gateway cover most of what matters here. 

You do not need to become a security expert to run OpenClaw AI safely, but skipping this step entirely is the one shortcut worth avoiding.

Matching Specs to Real Hosting Plans

Once you know which tier fits your plans, the actual VPS choice becomes simple. 

The 2 vCPU, 4 GB plan comfortably covers the text-only baseline.

 Moving to a 4 vCPU, 8 GB plan gives you room for browser automation or a couple of agents without constantly watching your resource usage.

Truehost UK’s VPS plans line up cleanly with both tiers, with NVMe storage as standard, so you are not stuck choosing between the right specs and reasonable performance.

 Picking a plan that already fits your use case, rather than the cheapest option that technically starts up, saves you an upgrade and a migration a few months down the line.

Upgrading later is usually possible without losing your data, but it still involves downtime and some reconfiguration. 

Choosing the first time correctly is the simpler path whenever you already know what your agent will be doing.

Bringing It All Together

The right VPS for OpenClaw AI comes down to one honest question: what will your agent actually be doing?

 A quiet text-only bot is happy on modest specs. 

Browser automation and multiple agents both push you toward more RAM and CPU, and it is far easier to size correctly up front than to migrate a live agent later. 

Get the hardware right, add the handful of software prerequisites, and the rest of the setup is straightforward from there.

If you are still unsure which tier best describes your plans, start with the text-only baseline and upgrade as soon as you enable your first browser task. 

That is the one signal that reliably tells you it is time to move up.
