Windsurf

Windsurf (formerly Codeium's IDE) is an AI-first code editor that goes beyond autocomplete to offer agentic coding capabilities. The Cascade feature acts as an AI pair programmer that can understand your codebase, plan changes across multiple files, and execute complex coding tasks independently. Unlike simple code completion, Windsurf's AI can search your codebase for relevant context, understand project architecture, create and modify files, run terminal commands, and iterate on its own output. It supports context from documentation, URLs, and codebases through deep indexing. Windsurf includes traditional copilot features like inline code completion, chat-based assistance, and code explanation. The editor is built on VS Code architecture for familiarity, supports all major programming languages, and offers a free tier that makes advanced AI coding accessible to individual developers.
