Windsurf is an agentic AI-powered IDE developed by Codeium (now under Cognition) that evolved from a code completion extension into a full standalone development environment. It addresses the challenge of maintaining developer flow while leveraging AI by deeply integrating intelligent code assistance into every part of the editing experience. Windsurf focuses on keeping developers in a state of productive flow rather than constantly context-switching between coding and AI interactions.
The centerpiece of Windsurf is Cascade, an agentic AI assistant that can plan and execute multi-step edits across your entire project, call tools, and leverage deep repository context to make intelligent changes. Tab and Supercomplete provide fast autocomplete with fill-in-the-middle and multi-line suggestions that are aware of terminal context. Windsurf also includes built-in app previews that let you see web application changes inside the editor, and it supports one-click Netlify deployments via Cascade tool calls. The IDE supports multiple frontier models including Claude, GPT, and Gemini, giving developers flexibility in choosing their preferred AI backend.
Windsurf targets professional developers and development teams who want a deeply integrated AI coding experience without sacrificing the familiar VS Code editing workflow. It is particularly well-suited for web development, full-stack projects, and teams that need collaborative AI-assisted development. The pricing structure includes a free tier with 25 prompt credits per month, a Pro plan at $15/month with 500 credits, a Teams plan at $30/user/month, and an Enterprise plan at $60/user/month with advanced security features and zero data retention defaults.
