Windsurf, released by Codeium in November 2024, is an AI-native code editor built on VS Code that directly competes with Cursor. Its standout feature is Cascade, an agentic AI engine designed for deep codebase understanding and autonomous multi-step coding tasks.
**Cascade Engine**
Cascade is what differentiates Windsurf from standard AI coding assistants. It maintains awareness of your entire codebase, tracks changes across a session, and can execute complex multi-file tasks autonomously — creating files, modifying imports, running terminal commands, and iterating based on errors.
**Codebase Indexing**
Windsurf indexes your entire repository on first open and keeps the index updated as you work. This enables genuinely context-aware suggestions that reference your project's actual architecture rather than generic patterns.
**Write vs Talk Mode**
Cascade operates in two modes: Write (autonomous code changes) and Talk (explanations and discussion). This distinction is useful for controlling when you want AI to act versus advise.
**Model Support**
Windsurf uses Codeium's own models as well as offering access to Claude 3.5 Sonnet and GPT-4o for users who prefer third-party models.
**VS Code Compatibility**
Full VS Code extension compatibility means migration is frictionless for existing VS Code users.
**Pricing**
Free tier with generous limits. Pro plan at $15/month. Significantly cheaper than Cursor Pro at $20/month for comparable capability.
**Verdict**
Windsurf is a genuine Cursor competitor and in some agentic scenarios surpasses it. The lower price point makes it the better starting point for developers new to AI-native IDEs.
