Continue Dev vs GitHub Copilot: Open Source Comparison

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.

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.

Key Features of Continue Dev

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.

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?

Choose GitHub Copilot if you:

Conclusion

Both Continue Dev and GitHub Copilot represent solid choices for AI-assisted coding. The decision ultimately depends on your priorities: maximum control and privacy with Continue Dev, or polished integration and convenience with GitHub Copilot. Many developers actually use both—Continue Dev for privacy-sensitive projects and Copilot for quick prototyping.

If you work on both sensitive and general-purpose projects, running both tools side by side is straightforward since neither conflicts with the other in VS Code.
