How to Set Up OpenClaw With Ollama: Run a Free, Private AI Agent Locally

Running an AI agent that can read your emails, manage your calendar, browse the web, and automate tasks across your apps — all without sending a single byte of data to a third-party server. That is what OpenClaw + Ollama gives you.

OpenClaw is the open-source AI agent framework that took GitHub by storm (321,000+ stars). Ollama is the tool that lets you run large language models locally on your own hardware. Put them together and you get a fully private, zero-cost AI assistant running entirely on your machine.

Why Should You Run OpenClaw With Ollama?

• Zero API costs — No per-token charges. No surprise bills. The LLM runs on your hardware for free.
• Complete data privacy — Your conversations, files, emails, and calendar data never leave your machine.
• No rate limits — Run as many queries as your hardware can handle.
• No internet dependency — Once the model is downloaded, the AI works offline (except for internet-dependent tasks).
• Full control — Choose your model, configure your agent, and modify anything you want.

The trade-off is that you need decent hardware and local models are not as capable as cloud models like Claude or GPT-4. But for the majority of daily automation tasks, a good local model is more than enough.

What Hardware Do You Need?

Mac users: Apple Silicon shares unified memory between CPU and GPU, so a Mac Mini M4 with 32 GB RAM can comfortably run 14B-32B models — this is why Mac Minis are one of the most popular setups for self-hosted OpenClaw.

How Do You Install Ollama?

# macOS / Linux
curl -fsSL https://ollama.com/install.sh | bash

# Verify installation
ollama --version

You need Ollama 0.17 or later for OpenClaw integration.

How Do You Launch OpenClaw With Ollama?

A single command handles everything:

ollama launch openclaw

Ollama detects whether OpenClaw is installed, installs it if needed, prompts you to select a model, configures the provider, installs the gateway daemon, activates web search, and starts the agent.

# Specify a model directly
ollama launch openclaw --model glm-4.7-flash

# Headless mode for automation
ollama launch openclaw --model kimi-k2.5:cloud --yes

Which Model Should You Choose?

Models to avoid: Under 7B parameters (struggle with tool-use), older Llama/Mistral models (unreliable tool calling), any model with less than 64K context.

How Do You Connect Messaging Apps?

openclaw configure --section channels

Connect WhatsApp (via QR code), Telegram (via bot token), Discord (via bot token), Slack (via app integration), iMessage (Mac only), Signal (via Signal CLI), or the built-in web chat.

How Do You Configure the Ollama Provider?

The easiest approach — set one environment variable and OpenClaw auto-discovers all Ollama models:

export OLLAMA_API_KEY="ollama-local"

Critical Configuration Warning

Do NOT use the /v1 OpenAI-compatible URL. This is the single most common mistake:

# WRONG — breaks tool calling
"baseUrl": "http://localhost:11434/v1"

# CORRECT — use native Ollama API
"baseUrl": "http://localhost:11434"

Using /v1 breaks tool calling and causes models to output raw tool JSON as plain text instead of executing actions.

How Do You Troubleshoot Common Issues?

Agent Hangs or Times Out

OpenClaw disables streaming by default for Ollama. Use a faster model, reduce context size, or increase the timeout. The Qwen3.5 35B-A3B MoE model (112 t/s) is specifically good here.

"Model Not Allowed" Error

Model names must match your provider config exactly. Run ollama list and copy-paste the exact name.

Tool Calling Not Working

Almost always caused by using the /v1 URL or an incompatible model. Use the native Ollama URL and switch to a Qwen3 or Qwen3.5 model.

What Is the Hybrid Approach?

The smartest setup combines local and cloud models:

• Local models (60-70% of tasks) — Routine automation, simple queries, file management, scheduling
• Cloud models (30-40% of tasks) — Complex reasoning, multi-step debugging, architecture decisions

Frequently Asked Questions

How much does OpenClaw with Ollama cost?

Nothing for the software. OpenClaw is free and open source. Ollama is free. The models are free. Your only costs are hardware and electricity.

Can I run OpenClaw with Ollama on a Mac?

Yes — and Macs are one of the best platforms for this. Apple Silicon shares unified memory between CPU and GPU, so a Mac Mini M4 with 32 GB RAM can comfortably run 14B-32B models.

What is the best model for OpenClaw with Ollama?

For most users: glm-4.7-flash as a balanced default or Qwen3.5 27B if your hardware can handle it. The Qwen3.5 family has the best tool-calling reliability with OpenClaw as of March 2026.

Does OpenClaw with Ollama work offline?

Partially. The LLM inference works offline once the model is downloaded. But tasks that need the internet (email, web search, calendar sync) still require connectivity.

Can I use OpenClaw with Ollama and cloud APIs at the same time?

Yes. You can configure multiple providers in OpenClaw and route different tasks to different models.
