How to Use Claude Opus for Free Using GitLab

Want to use Claude Opus — one of the most capable coding models on the market — completely free? You might already know that direct Claude subscriptions cost $20/month (Pro), or you’re limited by API rate limits.

In this blog post, I’ll walk you through exactly how to set this up, what you get for free, and how to make the most of it before the trial expires.

Step-by-Step: How to Use Claude Opus Models on GitLab (Free)

Step 1: Create a GitLab Free Trial Account

1. Go to GitLab
2. In the top-right corner, click “Get Free Trial”
3. Enter your details:
– Full name
– Email address
– Password
– Select your role (Software Developer, etc.)
– Select your country/region (Pakistan, India, US, etc.)
– Company name (optional — you can enter your name)
4. Click “Continue to GitLab”

Step 2: Verify Your Email

1. Check your email inbox for a verification code from GitLab
2. Copy the verification code and enter it on GitLab to verify your email address

Step 3: Complete Your Profile

1. Fill in your profile details
2. Select your role: Software Developer (or whatever matches your background)
3. Select who will be using GitLab: “Just me” or “Team” depending on your needs
4. Select your region/country

Step 4: Create Your First Project

1. On the GitLab dashboard, click “Create blank project”
2. Name your project (e.g., “Test Project”)
3. Click “Create project”

You’ll see a message that says “30 days left in trial” — this confirms your free trial is active and that you have access to Claude Opus.

Step 5: Access Claude Opus

1. On the bottom-right corner of your dashboard, look for the chat area. You will see a model already selected. Click on the model name
2. Scroll down through available models to find:
– Claude Opus 4.5
– Claude Opus 4.6
– Claude Opus 4.8 (newest version)
3. You can also search for specific models in the search bar
4. Select Claude Opus 4.6 (or your preferred version)

Step 6: Test Claude with a Simple Question

Let’s verify it’s working:

> Prompt: “Hey, how are you? Which model are you? And what can you do best?”

Claude will respond with something like:
> “I’m doing great! I’m Claude Opus 4.6, powered by GitLab…”

This confirms that the connection is live and that Claude is ready to work on your project.

Step 7: Assign Claude a Real Task

Now let’s test Claude’s real power — building something:

> Prompt: “Can you please build me a landing page for my design agency? It should be modern and functional. Also, add a small utility tool — a color palette generator.”

Claude will:
1. Plan the project structure
2. Create the files (HTML, CSS, JS)
3. Ask for permission to commit the changes
4. Ask for permission to push to the repository
5. Create a merge request with all the changes
6. Provide a detailed summary of everything built

Step 8: Approve and Merge the Request

1. Claude will ask for permission to commit and push → Click Approve
2. A merge request will be created with a number (e.g., “!1”)
3. Click on the merge request
4. Click Merge (bottom of the page, labeled “Ready to merge”)

Step 9: Test Your Built Project

1. Go back to your project
2. Click “Code” → “Download source code”
3. Choose your format (recommended: ZIP)
4. Save and extract it
5. Double-click index.html to open in your browser
6. You’ll see a complete landing page with:
– ✅ Hero section
– ✅ Services section
– ✅ Portfolio section
– ✅ Testimonials
– ✅ Color palette generator tool
– ✅ Contact form
– ✅ Footer

Step 10: Iterate (Free & Instant)

Want to make changes? Go back to GitLab and say:

> “Change the hero text to ‘…'”
> “Add a dark mode toggle”
> “Make the contact form functional with [specific service].”

Claude will update the code and create another merge request. Each change goes through the normal Git workflow — approve and merge.

Tips to Maximize Your 30-Day Trial

1. Plan your projects before starting — know what you want to build so you don’t waste trial days on brainstorming

2. Start with a clear, detailed prompt — specify exactly what you want: landing page features, color schemes, content sections, utility tools

3. Build one project fully before starting another — complete one thing, test it, iterate, then move on

4. Use the Git workflow — don’t just chat with Claude; let it build inside a real repository so you own the code

5. Export your code before the trial ends — download ZIP files of everything Claude builds for you

6. Ask Claude to explain what it built — you’ll learn faster when you understand the code it generates

Frequently Asked Questions
