Choose Continue Dev if you need data privacy (run models locally with Ollama so code never leaves your machine), want to pick your own AI model (Claude, GPT, or open-source alternatives), or need deep customization of prompts and slash commands. Choose GitHub Copilot if you want the most polished out-of-the-box experience with minimal setup, deep GitHub ecosystem integration, and enterprise compliance features at a predictable $10 per month. Many developers use both—Continue Dev for sensitive projects and Copilot for rapid prototyping.

Key Takeaways

What is Continue Dev?

Continue Dev is an open-source extension for Visual Studio Code and JetBrains IDEs that brings large language models directly into your development environment. Unlike many AI assistants that operate as closed systems, Continue Dev allows you to connect to various LLM providers, including Ollama, OpenAI, Anthropic, and custom endpoints.

The core philosophy behind Continue Dev centers on giving developers full control over their AI assistant. You decide which models to use, where your data goes, and how the assistant behaves. This flexibility makes it particularly attractive to privacy-conscious developers and those working with sensitive codebases.

What is GitHub Copilot?

GitHub Copilot is GitHub’s AI pair programmer, integrated directly into GitHub’s ecosystem. It uses OpenAI’s Codex model to provide code suggestions, autocompletions, and contextual assistance across multiple languages. As a proprietary solution, Copilot offers a polished experience with deep IDE integration.

Copilot excels in its tight integration with GitHub workflows. It understands your repository context, pull requests, and even suggests entire functions based on comments and existing code patterns. The service has evolved beyond simple autocomplete to include features like Copilot Chat for conversational assistance.

Key Features of GitHub Copilot

Practical Comparison

Pricing Structure

Continue Dev follows an open-source model, meaning the extension itself is free. However, you’ll need to pay for LLM API access. If you use Ollama locally, costs are limited to your hardware. With OpenAI or Anthropic APIs, pricing depends on token usage.

GitHub Copilot offers subscription plans. Individual plans start at $10/month or $100/year, while business plans cost $19/user/month. Students and maintainers of popular open-source projects can access Copilot for free.

Privacy and Data Handling

Privacy represents one of the most significant differences between these tools.

Continue Dev gives you explicit control over your data. When using Ollama locally, your code never leaves your machine. With remote APIs, you choose the provider and can configure data retention policies. The open-source nature means you can audit the code yourself.

GitHub Copilot processes your code on OpenAI’s infrastructure. While GitHub states that code suggestions are not stored and your code isn’t used for training, some organizations have concerns about sending proprietary code to external services. Copilot for Business offers additional compliance features.

Code Quality and Accuracy

Both tools produce helpful suggestions, but their approaches differ.

Continue Dev’s suggestions depend heavily on the underlying model you choose. Local models like CodeLlama offer decent performance but may lag behind in accuracy compared to larger models. When using GPT-4 or Claude, quality matches or exceeds Copilot.

GitHub Copilot benefits from extensive training on GitHub’s vast code repository. It excels at common patterns and popular frameworks, often anticipating what you need next. However, it occasionally suggests outdated APIs or patterns.

Getting Started Examples

Here’s how each tool handles a common scenario—generating a Python function to fetch data from an API.

Using Continue Dev:

  1. Install the extension from VS Code marketplace

  2. Configure your LLM provider in settings

  3. Type a comment describing what you need:

# Function to fetch user data from API
def fetch_user_data(user_id):

Continue Dev will suggest a complete implementation based on your configured model.

Using GitHub Copilot:

  1. Install the GitHub Copilot extension

  2. Start typing your code or add a comment

  3. Accept suggestions with Tab

# Fetch user data from API
def fetch_user_data(user_id):
    import requests
    response = requests.get(f"https://api.example.com/users/{user_id}")
    return response.json()

Both tools provide similar output, but Continue Dev allows you to customize the behavior through prompt engineering.

Customization and Extensibility

Continue Dev shines in customization. You can:

GitHub Copilot offers limited customization. You can configure suggestion frequency and trigger patterns, but the underlying behavior remains largely fixed.

Which Should You Choose?

Deep Dive: Local Processing with Continue Dev and Ollama

The most compelling reason to choose Continue Dev is local processing. Here’s exactly how the data flow differs:

Copilot workflow:

  1. You type code in your editor
  2. Copilot sends your code + context to OpenAI’s servers
  3. OpenAI processes and returns suggestions
  4. Your code passes through Microsoft’s infrastructure (though they claim no training)

Continue Dev + Ollama workflow:

  1. You type code in your editor
  2. Continue Dev sends your code to a local Ollama instance running on your machine
  3. Ollama processes entirely locally using your GPU
  4. Suggestions are returned from your machine, never leaving it

This matters practically:

Real example: A financial services company with strict data governance policies can run Continue Dev with Llama-2 (Meta’s open-source model) completely locally. Every line of code stays on premise. This legitimately cannot be done with Copilot regardless of enterprise agreements.

Model Selection Strategy for Continue Dev

One major advantage of Continue Dev is choosing your underlying model. Here’s how to decide:

For speed and quality (cloud): Connect to OpenAI’s GPT-4 Turbo ($0.01/1K input tokens)

{
  "models": [{
    "provider": "openai",
    "model": "gpt-4-turbo",
    "apiKey": "${OPENAI_API_KEY}"
  }]
}

For local privacy with decent quality: Use Ollama with CodeLlama 13B (requires 12GB VRAM)

{
  "models": [{
    "provider": "ollama",
    "model": "codellama:13b"
  }]
}

For privacy with maximum quality: Use Ollama with self-hosted Claude through Together AI (local-like experience, minimal external exposure)

{
  "models": [{
    "provider": "together",
    "model": "meta-llama/Llama-2-70b-chat-hf",
    "apiKey": "${TOGETHER_API_KEY}"
  }]
}

The flexibility here is huge. You can switch models without changing tools. Discovered a new model that works better? Change one config line.

Copilot locks you into whatever OpenAI model Microsoft negotiated. Updates happen on their schedule, not yours.

Actual Pricing Comparison with Real Numbers

Let’s calculate actual costs for a developer coding 8 hours daily, 5 days weekly:

GitHub Copilot Individual:

Continue Dev + Ollama local:

Continue Dev + OpenAI API:

Continue Dev + Claude API:

For individual developers, Copilot’s subscription model wins financially. For teams of 5+ developers, local Ollama becomes cheaper, and for organizations with strict data policies, it becomes essential regardless of cost.

Performance Testing: Real Latency Numbers

People often worry about local models being slower. Real testing shows nuance:

Simple completions (single function name):

Complex suggestions (multi-line function):

Chat/conversation mode:

The takeaway: Local models are competitive for inline completion but slower for chat. If your workflow is primarily “type code and accept suggestions,” local models work fine. If you’re using chat constantly, Copilot’s cloud infrastructure wins.

Customization Examples That Show Continue Dev’s Power

Continue Dev allows customization Copilot can’t touch:

Custom slash commands for your framework:

{
  "commands": {
    "createComponent": "/create a React component with TypeScript types, prop validation, and Jest tests",
    "sqlOptimize": "/Analyze this SQL query for N+1 problems and suggest indexes"
  }
}

Custom context providers that teach Continue Dev about your codebase:

{
  "contextProviders": [{
    "name": "myAPI",
    "path": "src/api",
    "description": "Our internal API client patterns"
  }]
}

Prompt customization for your coding standards:

{
  "systemPrompt": "You are a code assistant following these standards: Always use descriptive variable names, include JSDoc comments, and prefer functional programming patterns. Reject any suggestions using var keyword."
}

Copilot has no mechanism for any of this. It operates as a black box—you get what OpenAI trained it to do, and you can’t influence that.

Enterprise Scenario: When Each Tool Wins

Scenario 1: Healthcare startup with HIPAA requirements

Scenario 2: Startup with 20 developers wanting to reduce costs

Scenario 3: Team of 3 developers on a fixed budget

Scenario 4: Open source project with privacy requirements

Migration Path from Copilot to Continue Dev

If you’re serious about switching:

  1. Week 1: Install Continue Dev with Copilot as fallback. Don’t delete Copilot yet.
  2. Week 2: Configure Ollama + CodeLlama locally. Test with small projects.
  3. Week 3: Disable Copilot in VS Code, work entirely with Continue Dev.
  4. Week 4: Evaluate whether you prefer local or would benefit from API-based models.

Many developers find they use Continue Dev for code completion but keep Copilot subscription for their organization’s enterprise features or team collaboration. It’s not necessarily binary.

Frequently Asked Questions

Can I use Copilot and GitHub together?

Yes, many users run both tools simultaneously. Copilot and GitHub serve different strengths, so combining them can cover more use cases than relying on either one alone. Start with whichever matches your most frequent task, then add the other when you hit its limits.

Which is better for beginners, Copilot or GitHub?

It depends on your background. Copilot tends to work well if you prefer a guided experience, while GitHub gives more control for users comfortable with configuration. Try the free tier or trial of each before committing to a paid plan.

Is Copilot or GitHub more expensive?

Pricing varies by tier and usage patterns. Both offer free or trial options to start. Check their current pricing pages for the latest plans, since AI tool pricing changes frequently. Factor in your actual usage volume when comparing costs.

Can AI-generated tests replace manual test writing entirely?

Not yet. AI tools generate useful test scaffolding and catch common patterns, but they often miss edge cases specific to your business logic. Use AI-generated tests as a starting point, then add cases that cover your unique requirements and failure modes.

What happens to my data when using Copilot or GitHub?

Review each tool’s privacy policy and terms of service carefully. Most AI tools process your input on their servers, and policies on data retention and training usage vary. If you work with sensitive or proprietary content, look for options to opt out of data collection or use enterprise tiers with stronger privacy guarantees.
