Windsurf, formerly known as Codeium, is an advanced AI-powered IDE that combines intelligent code completion with agentic AI capabilities for a seamless coding experience. Its standout feature is Cascade, an agentic AI assistant that understands your entire codebase, suggests multi-file edits, runs terminal commands, and works alongside you as a coding partner. Cascade plans multi-step edits, calls tools, and uses deep repository context to deliver accurate suggestions. The editor features Memories, which remembers your codebase and coding patterns for increasingly personalized assistance over time. Windsurf includes automatic lint fixing, MCP support for connecting AI workflow tools, live previews, and Netlify deployment integration. The platform supports all premium AI models and offers the proprietary SWE-1.5 model optimized for software engineering tasks. For teams and enterprises, Windsurf provides centralized billing, admin dashboards with analytics, SSO with access control, RBAC, and deployment flexibility including cloud, hybrid, and self-hosted options. The Zero Data Retention policy is default for Teams and Enterprise plans, ensuring user code is never used for training. At $15 per month for the Pro plan with 500 credits, Windsurf offers competitive pricing against alternatives like Cursor.
