OpenClaw is 100% free and open source. There's no license fee, no subscription, no per-seat pricing. You download it, install it, and it's yours.

But running an autonomous AI agent isn't free. The real cost comes from two things: where you host it and which AI models you use. Most people spend between $5 and $50 per month. Power users running it 24/7 with premium models can hit $100-150/month.

Here's exactly where every dollar goes.

The Quick Answer

Usage Level Hosting AI Models Total/Month
Free tier Local machine or Oracle Cloud free Gemini Flash (free) or Ollama (local) $0
Light user Local machine Gemini Flash + occasional Claude/GPT $5-15
Daily driver VPS ($6-24/mo) Mix of models (Codex/Sonnet + Flash) $25-60
Power user VPS ($24/mo) + backup Premium models (Codex) + high volume $80-150

If you just want to try OpenClaw, you can run it for $0 using a free cloud VM and free-tier AI models. If you want it running 24/7 as a real assistant, plan for $25-60/month.

Part 1: Hosting Costs

OpenClaw needs to run somewhere. It's a Node.js app, so it's not heavy, but it does need to stay running if you want it available on your phone via WhatsApp or Telegram.

Option A: Your Own Machine ($0)

Run it on your laptop, desktop, Mac Mini, or a Raspberry Pi sitting on your desk. Cost: nothing beyond what you already pay for electricity.

Pros: Free, fast, full control, your data never leaves your house.

Cons: Only works while your machine is on. If you close your laptop, OpenClaw goes offline. Not ideal if you want to message it from your phone while you're out.

Best for: Trying it out, weekend projects, home automation.

Option B: Cloud VPS ($5-32/month)

The most popular setup. Rent a small virtual server from DigitalOcean, Hetzner, Linode, or similar.

Provider Spec Price
Oracle Cloud Free tier (ARM, 24GB RAM) $0
Hetzner CX22 (2 vCPU, 4GB RAM) $5/mo
DigitalOcean Basic (2 vCPU, 4GB RAM) $24/mo
DigitalOcean + backup Same + weekly snapshots $32/mo

Oracle Cloud's free tier is genuinely free and works well. The catch: signup can be tricky (they reject some accounts), and availability varies by region.

Hetzner is the sweet spot for most people. $5/month gets you a solid VPS in Europe. DigitalOcean runs a bit more but has data centers everywhere and great documentation.

How much RAM do you actually need? OpenClaw itself uses under 500MB. But if you're running browser automation, scraping, or multiple sub-agents, 4GB is the minimum. We've had out-of-memory issues on 4GB droplets during heavy browser automation. If you plan to do browser work, consider 8GB.

Option C: Managed Hosting ($29-59/month)

Services like GetOpenClaw and Elestio handle everything for you. No SSH, no config files, no Linux commands.

Pros: Zero setup, automatic updates, support if something breaks.

Cons: Less control, can't install custom system packages, costs more.

Best for: People who want OpenClaw running but don't want to manage a server.

Option D: Raspberry Pi ($50-100 one-time)

A Raspberry Pi 5 (8GB) costs around $80 and runs OpenClaw comfortably. It sits on your desk, uses 5 watts of power (~$5/year electricity), and stays online 24/7.

Pros: One-time cost, runs at home, full privacy, surprisingly capable.

Cons: Slower than a VPS for heavy AI workloads. No browser automation unless you connect a display.

Plenty of people in the community run OpenClaw on a Pi as their always-on assistant. It works well for messaging, scheduling, email triage, and other lightweight tasks. See our blueprint on building a home AI hub for an example.

Part 2: AI Model Costs (The Big Variable)

This is where most of your money goes. OpenClaw doesn't include an AI model. It connects to one (or several), and you pay the model provider based on how much you use it.

Think of it like a phone: OpenClaw is the phone (free), and the AI model is your carrier plan.

The Model Menu

Model Provider Input Cost Output Cost Best For
Gemini 2.5 Flash Google Free tier / $0.15/MTok Free tier / $0.60/MTok Routine tasks, heartbeats, quick lookups
GPT-4o OpenAI $2.50/MTok $10.00/MTok General tasks, writing, analysis
Claude Sonnet 4 Anthropic $3.00/MTok $15.00/MTok Coding, complex reasoning
Claude Codex Anthropic (via OpenAI Codex) Per-plan pricing Per-plan pricing Heavy daily use, coding agents
Ollama (local) Your hardware $0 $0 Privacy, zero cost, simpler tasks

MTok = million tokens. One token is roughly 4 characters of English text. A typical back-and-forth message exchange uses 2,000-5,000 tokens.

What Real Users Actually Spend

Light use (checking in a few times a day): $5-15/month. You ask it to check your calendar, draft an email, look something up. Maybe 50-100 exchanges per day on a cheap model.

Moderate use (daily driver): $20-40/month. Morning briefings, email triage, calendar management, occasional research tasks, some coding help. Running heartbeats every 30 minutes.

Heavy use (always-on assistant + automation): $60-150/month. 24/7 heartbeats, browser automation, sub-agent spawning, lead generation pipelines, multi-step research tasks. Premium models for complex work.

The Secret: Model Routing

Here's how experienced users keep costs down. OpenClaw supports model routing, which means you can use different AI models for different tasks:

One setup we've seen: set your default model to Gemini Flash for heartbeats and routine tasks, then switch to Codex/Sonnet when you need real thinking. This keeps your bill 60-70% lower than running premium models for everything.

You configure this in OpenClaw's config file:

{
  "agents": {
    "defaults": {
      "model": {
        "primary": "google/gemini-2.5-flash"
      }
    }
  }
}

Then use /model in chat to switch to a premium model when you need it, or set up automatic routing rules based on task type.

Part 3: Hidden Costs to Watch For

Runaway Token Usage

If you set heartbeats too frequently (every 5 minutes instead of every 30), or if your agent gets stuck in a loop, you can burn through tokens fast. Set spending alerts with your API provider. Most (Anthropic, OpenAI, Google) let you configure monthly limits.

Browser Automation

Running Chrome through OpenClaw's browser relay uses more memory and can trigger additional API calls (screenshots, page analysis). Budget an extra $5-10/month if you're doing heavy browser work.

External API Keys

Some OpenClaw skills need their own API keys. Web search (Brave API), email verification, phone lookups, etc. These are usually cheap ($5-20/month) or have free tiers, but they add up if you use many.

Storage

If you're on a VPS, watch your disk space. OpenClaw's memory files, logs, and any data you scrape can grow over time. Most 25GB VPS plans are fine for months of use.

Part 4: Can You Run OpenClaw for Free?

Yes, genuinely. Here's the $0 setup:

  1. Hosting: Oracle Cloud free tier (4 ARM cores, 24GB RAM) or your own machine
  2. AI Model: Google Gemini Flash (free tier: 15 requests/minute, 1M tokens/day) or Ollama running a local model
  3. Messaging: Telegram bot (free to create via BotFather)

Limitations: Gemini's free tier has rate limits. Local models via Ollama are slower and less capable than cloud models. But for learning OpenClaw and running basic automations, it works.

Part 5: Is It Worth It?

Compare OpenClaw's cost to what it replaces:

Tool/Service Monthly Cost
Virtual assistant (part-time) $500-2,000
Zapier (Pro) $29-70
Motion (AI calendar) $19
Notion AI $10
ChatGPT Plus $20
Superhuman (email) $30
OpenClaw (replaces some/all of the above) $25-60

The people who get the most value are those who use OpenClaw to replace multiple tools or automate repetitive work. If it saves you 30 minutes a day on email, calendar, and research tasks, that's 15 hours a month. At any reasonable hourly rate, $25-60/month is a no-brainer.

See our blueprint on the 5-Day Automation Sprint where one user found $22,000 in missed tax deductions by letting OpenClaw analyze their finances. That's a pretty good ROI on a $25/month tool.

Frequently Asked Questions

Is OpenClaw really free?

Yes. The software is open source (MIT license). You can download, modify, and use it however you want. The costs come from hosting (optional) and AI model API usage (variable).

What's the cheapest way to run OpenClaw?

Oracle Cloud free tier + Gemini Flash free tier = $0/month. It's limited but functional. For a few dollars more, Hetzner ($5/mo) + Gemini Flash gives you a solid always-on setup.

Why is my API bill so high?

Usually one of three things: (1) heartbeats running too frequently, (2) an agent loop that keeps retrying, or (3) using an expensive model (Opus/Codex) for everything including simple tasks. Check your heartbeat interval and set up model routing.

How does OpenClaw compare to ChatGPT Plus?

ChatGPT Plus ($20/mo) gives you access to GPT-4o in a chat window. OpenClaw gives you an autonomous agent that can act on your behalf, across WhatsApp, Telegram, email, your file system, the web, and more. It's a different category: chat assistant vs. autonomous agent. Many people use both.

Can I use OpenClaw with a local model (no API costs)?

Yes. Install Ollama, run a model like Llama 3 or Qwen locally, and point OpenClaw at it. Zero API costs. The tradeoff is performance: local models are less capable than Claude or GPT-4o for complex tasks, and they need decent hardware (16GB+ RAM, ideally a GPU). See the Ollama blog's OpenClaw tutorial for setup instructions.

What model should I start with?

Start with Gemini 2.5 Flash (cheapest) to learn how OpenClaw works. Once you know what you want it to do, upgrade to Claude Sonnet 4 or GPT-4o for better results on complex tasks. Use model routing to mix cheap and premium models based on task type.
