Windsurf is an agentic AI code editor built by Codeium โ designed for developers who want an AI that doesn't just suggest the next line, but actually understands and works across your entire codebase. Its core feature, Cascade, is an AI agent that can plan, write, debug and refactor code across multiple files simultaneously, maintaining full context of what it has done and why.
Unlike GitHub Copilot, which primarily autocompletes within your current file, Windsurf's Cascade agent can receive a high-level task ("add authentication to this app" or "refactor this module to use the new API"), break it into steps, make the changes across relevant files and explain its reasoning โ more like a junior developer pair-programming than a code completion tool.
Windsurf is built on VS Code and maintains compatibility with VS Code extensions, making it a drop-in replacement for developers already in the VS Code ecosystem who want to upgrade to a more agentic AI experience.
Who is Windsurf for?
Developers working on complex multi-file projects who want an AI that maintains full codebase context, developers switching from Cursor looking for a free alternative with similar capabilities, and teams who want agentic code editing without Cursor's price point.
