Hey fellow AI tinkerers — if you're eyeing Moltbot (formerly Clawdbot) after seeing those viral demos, you're probably wondering: Is this thing actually free, or am I walking into another subscription trap?
I spent the last two weeks running Moltbot through my daily workflow — not the sanitized demo version, but the actual "keeping it alive 24/7 on a VPS while burning through API tokens" version. The short answer? The software itself is free. The infrastructure to run it? That's where your wallet opens.
Let me break down what it actually costs to run Moltbot in 2026, because "open-source" and "free to use" aren't the same thing.
Here's what caught me off guard: Moltbot's GitHub repository is MIT-licensed, meaning you can download, modify, and run the code without paying the creators a cent. But that's like saying a Tesla is "free" because you can download the blueprints — you still need to buy the parts and pay for electricity.

The MIT License gives you complete freedom:
This is genuinely free software. The catch? You're now responsible for everything else.

This is where things get expensive. Moltbot doesn't have its own AI brain — it connects to external AI models through APIs. You have three options:
Option 1: Claude API (Recommended)
Most users run Moltbot with Anthropic's Claude API because it handles tool calling better than alternatives. Here's what I measured over two weeks of moderate daily use:
At current pricing ($3 per million input tokens, $15 per million output tokens for Sonnet 4.5), my test setup burned through roughly $38 in the first month. I wasn't even running heavy automation — just daily chat, some file processing, and calendar management.
Real numbers from my test environment:
# Check your Anthropic API usage
curl https://api.anthropic.com/v1/usage \
-H "x-api-key: $ANTHROPIC_API_KEY" \
-H "anthropic-version: 2023-06-01"
After running this check mid-month, I discovered I'd already used 2.1M input tokens ($6.30) and 890K output tokens ($13.35). I wasn't expecting to hit $20 by day 15.
Option 2: OpenAI GPT-4
Some users prefer GPT-4 for coding tasks. Pricing is similar to Claude but tool calling behavior differs. Expect $20–60/month for moderate usage based on OpenAI's current pricing structure.
Option 3: Local Models (Ollama)
This is the "truly free" option — run open-source models like Llama 3.2, Qwen, or Mistral locally through Ollama. The API costs drop to $0, but:
I tested this with ollama run llama3.2:8b for three days. It worked for basic chat, but failed repeatedly on calendar integration and file processing tasks that Claude handled smoothly.
Moltbot needs to run 24/7 somewhere. You can't just close your laptop and expect it to keep responding to messages. Here are your realistic options:
VPS Hosting (Most Common)
I tested three budget-friendly providers:
I ran my test instance on Hetzner's CX22 ($6/mo). Setup took about 30 minutes following Moltbot's installation guide:
# Install Moltbot on Ubuntu 24.04 VPS
npm install -g moltbot@latest
moltbot onboard --install-daemon
# Configure to start on boot
sudo systemctl enable moltbot-gateway
sudo systemctl start moltbot-gateway
Home Server / Old Laptop (Free Hosting)
If you have a spare computer running 24/7, you can host Moltbot for free. I tested this on a 2019 MacBook Pro for comparison. It worked fine but:
Cloud Server Pricing Reality Check
The advertised "$2/month VPS" plans you see online? They won't run Moltbot reliably. I tried a $4 DigitalOcean droplet (1GB RAM) and it crashed within 6 hours under normal load. You need at least 2GB RAM, which puts minimum hosting at $6–10/month from reputable providers.
After two weeks of real-world testing, here's what Moltbot actually costs:
Minimum Monthly Budget (Light Usage)
Realistic Monthly Budget (Moderate Usage)
Heavy Usage / Multi-Agent Setup
Hidden Costs Nobody Mentions:
Compare this to alternatives:
The question isn't whether Moltbot is cheaper — it's whether the control and customization are worth the extra complexity.
I tested three alternatives to understand where Moltbot fits:
ChatGPT Plus ($20/month)
Macaron.im (Free tier available)

N8n + OpenAI (Self-hosted automation)
The Moltbot Sweet Spot: You should only choose Moltbot if:
If any of those don't apply, you're probably better off with a managed service.
At Macaron, we built the persistent AI assistant experience without the VPS hosting, API token juggling, or $20–50/month infrastructure costs Moltbot requires. If you want personalized AI tools without the DevOps overhead, try running one of your real tasks through Macaron and judge the results yourself. Free to start, no server setup, reversible anytime.
