OpenClaw is free. The software costs $0. It is open source under the MIT license with over 200,000 stars on GitHub. You download it, install it, run it. No subscription. No license fee. No hidden charges from the OpenClaw project itself.
But "free" needs context. Because while the software is free, running an AI agent costs money. You need an AI model to power it. You need something to run it on. And those two things have real costs attached.
Here is the full breakdown so you know exactly what to expect before you install.
What We Cover
The Software: $0 (Actually Free)
OpenClaw is MIT licensed. That means you can use it personally, commercially, modify it, redistribute it. No restrictions. No freemium wall. No "free for 14 days then pay up."
You install it with npm. One command. It runs on macOS, Linux, Windows, even a Raspberry Pi. The project is maintained by Peter Steinberger (founder of PSPDFKit) and a growing open source community.
So when someone asks "is OpenClaw free?" the answer is yes. The software itself is completely free. What costs money is what powers it.
AI Model API Costs: The Real Bill
OpenClaw needs a brain. That brain is an AI model like Claude, GPT-4o, or Gemini. You connect it via API key, and you pay per use based on tokens (chunks of text processed).
Here are the current rates as of March 2026:
| Model | Input (per 1M tokens) | Output (per 1M tokens) | Best For |
|---|---|---|---|
| Claude Opus 4.6 | $5.00 | $25.00 | Complex reasoning, heavy automation |
| Claude Sonnet 4.6 | $3.00 | $15.00 | Good balance of cost and capability |
| Claude Haiku 4.5 | $1.00 | $5.00 | Fast, simple tasks |
| GPT-4o | $2.50 | $10.00 | General purpose |
| Gemini 2.5 Pro | Free tier available | Free tier available | Budget setups, experimentation |
For most people running OpenClaw as a personal assistant (checking emails, managing calendars, answering questions, light automation), the monthly API bill falls between $5 and $30.
Heavy usage with Opus (running 13 agents, cron jobs every 30 minutes, constant sub-agent spawning) can push costs to $100-200/month. That is power-user territory.
Pro tip: You do not have to pick one model. OpenClaw lets you set different models for different tasks. Use Haiku for simple notifications and Opus for complex research. This alone can cut your bill by 50%.
Hosting: Where Your Agent Lives
OpenClaw needs to run somewhere 24/7 if you want it always available. You have three main options:
Option 1: Your Own Computer ($0)
Run it on your laptop or desktop. Costs nothing extra. The downside: it stops when your computer sleeps or shuts down. Fine for testing. Not great for a 24/7 assistant.
Option 2: Mac Mini or Home Server ($0/month after hardware)
A Mac Mini M4 running at home is a popular choice. It sips power (under $5/month in electricity), stays on 24/7, and handles OpenClaw without breaking a sweat. I run my entire setup on a Mac Mini. 13 agents, multiple cron jobs, always on.
The upfront cost is around $500-600 for a base Mac Mini. After that, your monthly hosting cost is basically zero.
Option 3: VPS (Cloud Server) ($5-15/month)
A VPS (Virtual Private Server) from providers like Hetzner or Contabo gives you a dedicated machine in the cloud. Always on, accessible from anywhere.
Hetzner is the community favorite. Around $7/month gets you 4 shared CPU cores, 8GB RAM, and SSD storage. That is more than enough for OpenClaw.
Contabo is the budget option at around $7/month for similar specs.
Minimum specs: 2 CPU cores, 4GB RAM, SSD storage. OpenClaw is lightweight. Node.js does not need much. The AI processing happens on the provider side (Anthropic, OpenAI servers), not on your machine.
Real Monthly Cost Examples
Here is what real setups actually cost per month:
| Setup | Hosting | API Cost | Total/Month |
|---|---|---|---|
| Personal assistant (light use) | $0 (laptop) | $5-10 | $5-10 |
| Personal assistant on VPS | $7 (Hetzner) | $10-20 | $17-27 |
| Business automation (Mac Mini) | $0 (own hardware) | $30-80 | $30-80 |
| Power user (13 agents, heavy crons) | $0 (Mac Mini) | $100-200 | $100-200 |
| Budget setup (Gemini free tier) | $0 (laptop) | $0 | $0 |
Yes, you can technically run OpenClaw for $0/month total using Google Gemini's free API tier on your own machine. The free tier gives you up to 15 requests per minute and 1,000 requests per day. For light personal use, that works.
How to Cut Your Costs in Half
Five concrete ways to lower your monthly bill:
1. Use cheaper models for simple tasks. Haiku at $1/$5 per million tokens handles notifications, simple lookups, and calendar checks. Save Opus for the heavy lifting.
2. Run local models with Ollama. OpenClaw supports local models through Ollama. Zero API cost. The trade-off is capability. Local models are getting better fast, but they still lag behind Claude and GPT-4o for complex tasks. Great for privacy-sensitive work though.
3. Set spending limits. Anthropic and OpenAI both let you set monthly spending caps on your API accounts. Set one. Seriously. An agent stuck in a loop can burn through $50 in an afternoon if you are not careful.
4. Batch your cron jobs. Instead of 6 separate cron jobs checking different things, combine them into one heartbeat check that runs every 30 minutes. Fewer API calls, same result.
5. Use prompt caching. Anthropic offers up to 90% discount on cached prompts. If your agent sends the same system prompt repeatedly (it does), caching dramatically reduces costs.
Watch out: The biggest unexpected cost is agent loops. If your agent gets confused and keeps retrying a failing task, it burns tokens fast. Always set spending limits on your API accounts before letting agents run unsupervised.
OpenClaw Cloud: The Managed Option
Do not want to manage servers, updates, and configurations yourself? OpenClaw Cloud (getopenclaw.ai) handles everything for you.
It offers a 7-day free trial. After that, you pay a subscription that covers hosting and management. Your agent runs in 60 seconds. No SSH, no Node.js, no firewall configuration. Security updates happen automatically.
The trade-off is cost. You pay more than self-hosting. But you get zero maintenance, automatic updates, and professional security. For non-technical founders, this is usually the right call.
If you want full control and do not mind getting your hands dirty, self-hosting with the one-command installer saves money long-term.
Compared to a Human Assistant
Put the numbers in perspective. A human virtual assistant costs $3,000-6,000/month. Add benefits and taxes, you are looking at $36,000-72,000/year. They work 8 hours a day, 5 days a week. They take vacations. They handle one task at a time.
OpenClaw at $30/month (typical business use) costs $360/year. It works 24/7. It runs multiple tasks simultaneously. It never takes a sick day. It remembers everything you told it six months ago.
Is it as good as a senior executive assistant? No. Not yet. But for 99% of the repetitive, organizational, research-heavy work that eats your day? It is more than enough. And it costs less than your coffee budget.
