Side-by-side comparison — features, pricing, pros and cons
GitHub's AI pair programmer, now extended with Agent Mode for autonomous task execution and Copilot Workspace for feature-to-PR workflows. The free tier was significantly expanded in late 2025, making it the first major AI coding tool with meaningful free access. Integrates natively into VS Code, JetBrains, and GitHub.com.
AI code editor by Codeium built around the Cascade agent architecture, where the AI maintains a persistent understanding of your entire coding session rather than responding to isolated prompts. Cascade can plan and execute multi-step tasks while the developer continues working, with "flows" that track intent across file edits, terminal commands, and test results. Priced at $15–30/mo as a direct Cursor competitor.
