| Description | 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. |
