Visit WindsurfWhat is Windsurf?
Windsurf is an AI-first integrated development environment created by Codeium, the company behind one of the most widely used AI autocomplete engines in the world. Codeium had already built a reputation for delivering fast, accurate code completions to over one million developers through their extension for VS Code, JetBrains, and other editors. In late 2024, they decided to go further: rather than just augmenting existing editors, they would build their own. The result is Windsurf — a full VS Code fork that reimagines the coding experience around AI from the ground up.
What sets Windsurf apart from other AI code editors is its "Flows" paradigm. While most AI coding tools operate in a request-response cycle — you ask a question, the AI answers — Windsurf introduces multi-step AI workflows that can plan, execute, and iterate on complex tasks with minimal user intervention. A Flow might involve reading your codebase to understand the architecture, generating a plan for a new feature, writing the code across multiple files, running tests, and fixing any failures — all triggered by a single natural language instruction from the developer.
At the heart of Windsurf's autonomous capabilities is Cascade, its agentic AI system. Cascade goes beyond what traditional AI chat or inline completion can do. It maintains awareness of your entire project structure, understands the relationships between files and modules, and can make coordinated changes across your codebase. When you ask Cascade to implement a feature, it doesn't just write code in one file — it traces dependencies, updates imports, modifies related tests, and adjusts configuration files as needed. This level of autonomy makes Windsurf particularly effective for larger projects where changes rarely happen in isolation.
Windsurf competes directly with Cursor, the other major VS Code fork in the AI coding space. The two editors share a similar philosophy — deep AI integration into a familiar VS Code interface — but differ in approach and pricing. Windsurf's Pro plan costs $15 per month compared to Cursor's $20, and its Cascade agent takes a more autonomous approach than Cursor's chat-centric workflow. For developers evaluating AI-powered editors in 2026, Windsurf represents a compelling option that combines Codeium's proven autocomplete technology with cutting-edge agentic AI capabilities.
Key Features
Cascade (Agentic AI)
Cascade is Windsurf's autonomous coding agent. It can plan multi-step implementations, write code across multiple files, run terminal commands, debug errors, and iterate on its own work. Unlike simple chat-based AI, Cascade maintains full context of your project and takes initiative — acting more like a junior developer than a search engine.
Flows (Multi-step Actions)
Flows let you chain together complex coding workflows into a single AI-driven operation. Describe a high-level goal — "add user authentication with JWT tokens" — and Windsurf breaks it into steps: scaffolding files, writing route handlers, adding middleware, creating tests, and wiring everything together. Each step builds on the last, maintaining coherence across the entire flow.
Supercomplete (Smart Autocomplete)
Built on Codeium's battle-tested autocomplete engine that serves over one million developers, Supercomplete goes beyond single-line suggestions. It predicts multi-line code blocks, understands your coding patterns, and adapts to your project's conventions. Completions arrive in under 200 milliseconds, making the experience feel instantaneous even on large codebases.
Command Mode
Command Mode gives you an inline prompt bar for quick, targeted AI edits. Select a block of code and describe the transformation you want — "convert to TypeScript", "add error handling", "optimize this loop" — and Windsurf applies the change directly in your editor with a diff view so you can review and accept or reject each modification before it takes effect.
Codebase Awareness
Windsurf indexes your entire project to build a semantic understanding of your codebase. It knows which functions call which, how modules relate to each other, and where your types and interfaces are defined. This deep awareness means AI suggestions are contextually accurate — not just locally correct but globally consistent with your project's architecture and conventions.
Terminal Integration
Windsurf's AI extends into the integrated terminal. Cascade can run shell commands, interpret output, and take action based on results — such as installing dependencies, running tests, or restarting development servers. When a command fails, Cascade reads the error output, diagnoses the issue, and suggests or applies a fix automatically without you having to switch contexts.
How to Get Started with Windsurf
Getting started with Windsurf is straightforward, especially if you are coming from Visual Studio Code. Download Windsurf from codeium.com/windsurf for Windows, macOS, or Linux. The installer takes about two minutes. On first launch, Windsurf offers to import your existing VS Code extensions, settings, keybindings, and themes — making the transition nearly seamless.
Once installed, create a free Codeium account to activate AI features. The free plan gives you access to Supercomplete autocomplete and basic Cascade usage so you can evaluate the tool before committing to a paid plan. Open any project folder and Windsurf will automatically begin indexing your codebase in the background — this usually takes less than a minute for projects under 100,000 lines of code.
To use Cascade, open the AI panel (Ctrl+Shift+L on Windows/Linux, Cmd+Shift+L on macOS) and describe what you want to accomplish in natural language. For quick inline edits, use Command Mode (Ctrl+I / Cmd+I) to open a prompt bar directly in your editor. Supercomplete works automatically as you type — just press Tab to accept suggestions. Within your first hour, you will likely find that Windsurf's AI capabilities significantly accelerate common coding tasks like writing boilerplate, implementing features, and debugging errors.
