If you’re using Anthropic’s command-line tool, you know it’s a productivity beast. But if you’re also staring at a $100 or $200 monthly bill for the “Max” plan, that beast is starting to eat your margins. Honestly, I’ve seen enough “API usage” invoices in my 14 years of development to know when a cost-to-benefit ratio is getting out of hand. Consequently, many developers are looking for ways to run Claude Code for free by leveraging local infrastructure.
The good news? Ollama recently dropped a massive update (v0.14.0+) that introduces compatibility with the Anthropic Messages API. This means we can now trick Claude Code into thinking it’s talking to Anthropic’s servers, while it’s actually pulling tokens from a local Llama 3 or Qwen model running on your own hardware.
Why You Should Run Claude Code for Free Locally
Privacy and cost are the obvious drivers here. However, as a senior dev, I care about something else: context control. When you run a local model via Ollama, you aren’t just saving money; you’re removing the “middleman” of proprietary rate limits. Furthermore, integrating local agents helps you avoid the technical debt in AI development that often comes from relying on shifting cloud-based model behaviors.
The Setup: Getting Your Environment Ready
First, ensure you have the latest version of Ollama. If you’re on Windows, PowerShell is your friend here. Once installed, you need to “pull” a model that actually knows how to code. I recommend qwen3-coder or codellama. Specifically, the Qwen3 series has been outperforming many others in logic-heavy tasks recently.
# Pull the model
ollama pull qwen3-coder:7b
# Verify version (needs to be 0.14.0 or higher)
ollama --versionConfiguring Claude Code to Use Ollama
This is where the magic happens. We need to redirect the Claude Code CLI to look at our local Ollama endpoint instead of Anthropic’s API. We do this by setting specific environment variables. Therefore, your terminal session needs these three keys to bridge the gap.
# Windows PowerShell
$env:ANTHROPIC_AUTH_TOKEN = "ollama"
$env:ANTHROPIC_API_KEY = "ollama"
$env:ANTHROPIC_BASE_URL = "http://localhost:11434"
# MacOS/Linux
export ANTHROPIC_AUTH_TOKEN="ollama"
export ANTHROPIC_API_KEY="ollama"
export ANTHROPIC_BASE_URL="http://localhost:11434"Now, when you run the claude command, it will hit your local Ollama instance. Use the --model flag to specify which model you pulled in the previous step. If you’re worried about hallucinations or context issues, check out my guide on AI coding agent context to keep your local setup sharp.

I tried running this in a fresh project folder and hit an immediate wall. Claude Code is designed to be “agentic,” meaning it wants to track its own changes. If you aren’t inside a Git repository, it will often throw an error saying it has “no version control context.” It’s a classic safeguard to prevent it from overwriting your entire disk by mistake. Consequently, always run git init before letting the agent loose, even for a simple “Hello World” script.
Look, if this Claude Code for Free stuff is eating up your dev hours, let me handle it. I’ve been wrestling with WordPress and AI integrations since the early days, and I can help you build a robust, cost-effective workflow that doesn’t break every time an API updates.
Final Takeaway: Local is the New Cloud
Running Claude Code for free using Ollama isn’t just a “hack” for people trying to save a few bucks. It’s a fundamental shift toward sovereign development. While local models might not yet match the raw reasoning of Claude 3.5 Opus, for 80% of daily refactoring, CSS tweaks, and boilerplate generation, they are more than capable. Stop paying for tokens you can generate in your own basement.
