Windsurf is an AI-native IDE from Codeium that introduces the concept of a "flow" - a deeply integrated AI agent that understands the full context of a developer's codebase and can take multi-step actions autonomously. Its Cascade agent can browse the web, run terminal commands, edit multiple files, and debug iteratively - going far beyond autocomplete to function as a true AI programming partner.

Best for: Developers wanting an AI-native IDE with a capable agentic coding assistant that can handle multi-step engineering tasks autonomously
