Agentic AI code editor that understands your full codebase.
Windsurf is an AI-powered IDE developed by Codeium, available for Windows, Mac, and Linux, built around an agentic AI called Cascade that can read, understand, write, and execute code across an entire project — not just the currently open file. Cascade operates in Flow mode, where it plans multi-step changes, runs terminal commands, interprets test output, and explains its reasoning as it works through a task. All standard IDE features including syntax highlighting, debugging, and Git integration are included. Windsurf is compatible with most VS Code extensions. The free tier provides a generous daily AI usage allowance. It is used by developers who want an AI that can take on larger, end-to-end coding tasks with minimal manual steering, rather than providing individual line completions.
