Github Copilot

For professional developers, GitHub Copilot is almost universally considered worth $10/month. GitHub's own studies show a 55% faster task completion for developers using Copilot, and independent surveys consistently show 70–85% of users report increased productivity. The ROI calculus is simple: if Copilot saves even 30 minutes per day, at a $50/hour developer rate, it pays for itself in one week. The Business plan at $19/user/month adds code referencing, security vulnerability filtering, and admin controls for teams.

Choose GitHub Copilot if you're happy with your current IDE (VS Code, JetBrains) and want AI as a supplement — Copilot integrates without requiring you to change your development environment. Choose Cursor if you're open to switching editors and want the most powerful AI-integrated experience — Cursor's Composer (multi-file editing), full codebase indexing, and AI-first interface provide deeper integration than Copilot's extension model. Many developers try Cursor and don't go back; others prefer staying in familiar tools.

No — GitHub Copilot requires an internet connection to generate suggestions. Completions are sent to GitHub's servers (running on Azure) for processing. This means it doesn't work in air-gapped environments. For organizations requiring on-premise AI coding assistance, Tabnine Enterprise or Amazon CodeWhisperer with a custom model offer deployment options that keep code on your infrastructure. GitHub has announced GitHub Copilot Enterprise with enhanced privacy controls but not fully on-premise deployment.
