You’re trying to choose between GitHub Copilot and Cursor as your coding assistant in 2025, but feeling overwhelmed by conflicting information and unsure which tool will actually help your workflow. This decision matters because the right coding assistant can save you hours daily, while the wrong choice might slow you down or create more bugs than it prevents.
Step-by-Step Fixes
Step 1: Run a Quick Compatibility Check
Open your main code editor right now. If you’re using VS Code, check if both extensions are available in the marketplace. For JetBrains IDEs, verify GitHub Copilot compatibility first. Cursor runs as its own fork of VS Code, so you’ll need to download their separate application from cursor.sh. This takes about 2 minutes and tells you immediately if either option works with your current setup.
Step 2: Test Both Free Trials Side-by-Side
GitHub Copilot offers a 30-day free trial through your GitHub account settings. Navigate to github.com/settings/copilot and click “Start free trial.” For Cursor, download their app and you’ll get 2 weeks free with their Pro features. Set up a simple test project – maybe a basic web app or script you’re familiar with. This hands-on comparison beats reading reviews every time.
Step 3: Check Your Language Support
Create a new file in your most-used programming language. Type a comment describing a function you commonly write. Watch how each tool responds. GitHub Copilot excels with mainstream languages like JavaScript, Python, and Java. Cursor shows stronger performance with TypeScript and React patterns. If you work with niche languages or frameworks, this test reveals which assistant actually understands your code.
Step 4: Measure Response Speed on Your Machine
Your computer specs affect performance more than most reviews mention. Open Task Manager on Windows or Activity Monitor on Mac. Start coding with each assistant active. GitHub Copilot typically uses 200-400MB RAM. Cursor, being a full IDE fork, needs 1-2GB. If your machine has less than 8GB RAM, this difference becomes noticeable fast.
Step 5: Test Offline Capabilities
Disconnect your internet and try coding. GitHub Copilot stops working entirely without connection. Cursor maintains some local functionality, though advanced features need internet. This matters if you code during commutes, flights, or have unreliable internet.
Step 6: Compare Monthly Costs Against Your Budget
GitHub Copilot costs $10/month for individuals or $19/month for business features. Cursor pricing starts at $20/month for Pro features. Calculate this against how many hours each tool saves you. If an assistant saves you 30 minutes daily, that’s 10+ hours monthly – likely worth either price for professional developers.
Likely Causes
Cause #1: Integration Conflicts
Your existing VS Code extensions might clash with these coding assistants. Check your extensions list for other autocomplete tools like TabNine or Kite. These create suggestion conflicts where multiple tools try completing your code simultaneously. Disable other AI assistants temporarily while testing. You’ll know this is happening when suggestions appear doubled or fight for the same space on screen.
Cause #2: Account Authentication Issues
Both tools require proper account setup. GitHub Copilot needs an active GitHub account with billing enabled. Check github.com/settings/billing to verify your payment method works. Cursor requires email verification and sometimes gets caught in spam filters. Search your spam folder for “Cursor verification” if signup seems stuck. Authentication problems show as endless loading spinners or “unauthorized” error messages.
Cause #3: Outdated IDE Versions
VS Code updates monthly, and both assistants require recent versions. Click Help > About in VS Code to check your version. Anything before version 1.82 (August 2023) causes compatibility problems. JetBrains IDEs need version 2023.2 or newer for smooth GitHub Copilot integration. Update your IDE first before troubleshooting further – this fixes 80% of setup issues.
When to Call a Technician
Stop troubleshooting yourself if you see system-wide performance drops after installation. When your entire computer slows down, not just the IDE, something deeper went wrong. Corporate firewalls also block these tools sometimes – if you’re on a company network and nothing connects, contact your IT department rather than fighting security policies.
Call for help when error messages mention “kernel panic,” “blue screen,” or system file corruption. These indicate installation damaged something important. A technician can safely remove problematic files without breaking your development environment.

Remember, the best coding assistant is the one that fits your specific workflow. Don’t feel pressured to choose based on popularity alone. Your coding style, project types, and hardware limitations matter more than general reviews. Take time with free trials, test with real projects, and trust your hands-on experience over anyone else’s opinion.
