Windsurf IDE Review: The Best AI IDE in 2025

In today's world of fast-paced software development, tools that boost productivity, streamline workflows, and reduce developer fatigue are no longer a luxury—they’re a necessity. Enter Windsurf IDE, a next-generation development environment built by the team at Codeium. Windsurf is an AI-native integrated development environment (IDE) designed to replace traditional IDEs like VS Code. It achieves this with intelligent, collaborative coding powered by machine learning, including smart agents, real-time collaboration, and powerful AI suggestions that feel more like working with a teammate than a machine. Unlike traditional IDEs that might tack on AI features, Windsurf is designed from its core to work alongside artificial intelligence.

Windsurf builds on the familiar foundation of Visual Studio Code, but don’t be fooled—this is far more than a simple extension or skin. It's a platform that includes intelligent agents, collaborative tools, and real-time code suggestions that feel more like working with a teammate than a machine.

Whether you're an experienced engineer, a startup founder building your MVP, or a CTO managing an enterprise team, Windsurf offers a fresh approach to writing software in the age of AI.

Why Windsurf Matters Right Now

The software development world has evolved. With AI transforming nearly every industry, it was only a matter of time before our code editors caught up. Windsurf IDE is one of the first tools to embrace this shift completely, offering a collaborative experience between human and machine.

Unlike basic autocomplete tools that only suggest snippets, Windsurf acts like a development partner. It learns your codebase, understands the project structure, and gives meaningful feedback. That means less time spent searching Stack Overflow and more time building.

The OpenAI Acquisition: A Strategic Move

In early 2025, OpenAI quietly acquired Windsurf in a strategic move to deepen its integration with the developer community and expand its influence beyond language models into developer tooling. The acquisition allowed Windsurf to leverage OpenAI’s most advanced models—including GPT-4o and future successors—directly within the IDE.

This partnership elevated Windsurf beyond a standalone AI IDE. It became OpenAI’s flagship interface for agent-based development workflows, enabling tighter model feedback loops, enhanced code understanding, and seamless interaction between human intent and machine execution.

The acquisition also signals OpenAI’s long-term strategy: not just offering APIs, but embedding AI into the environments where software is created—line by line, repo by repo.

Core Technologies That Power Windsurf

1. Cascade: Conversational Coding, Reimagined

Cascade is Windsurf’s flagship AI system. It transforms coding into a conversational experience, where you can write natural language commands and get real, context-aware suggestions. Instead of relying on keyword-based autocompletion, Cascade understands your entire codebase. It knows what you’re building, tracks your changes in real-time, and delivers intelligent suggestions that make sense. Under the hood, Cascade uses a persistent vector representation of your codebase to maintain context, enabling semantic code generation across files—not just token-based autocomplete. Think of it as pairing with a highly competent co-pilot who never needs a coffee break.

2. Supercomplete: Autocomplete, Supercharged

Traditional autocomplete finishes your line of code. Supercomplete finishes your thought. Technically, Supercomplete leverages multi-file awareness and prompt chaining techniques, offering full function scaffolding based on intent. With Windsurf's Supercomplete feature, entire blocks of code—functions, classes, even boilerplate-heavy modules—can be generated in a single step. It understands how different files in your project relate to each other, allowing for multi-file-aware suggestions that reduce context switching and manual stitching.

3. Flows: Real-Time Sync Between Developer and AI

Flows is a system that keeps you and the AI on the same page—literally. By intelligently tracking and synchronizing user actions with AI-generated changes in real-time, it tracks not only what you’re doing but also what the AI is doing, making the collaboration feel seamless. The result is a shared mental model between the developer and the tool.

This also extends to team-based collaboration. If you’re working in a larger team, Flows allows multiple users to co-edit a file with the AI actively supporting all contributors in real-time.

4. Broad Language and Extension Support

Windsurf isn’t just for Python or JavaScript. It supports over 70 programming languages, including Go, Rust, Java, and TypeScript. Even better, it’s fully compatible with the VS Code extension ecosystem, so most of your existing tools will continue to work right out of the box.

Competitive Pricing That Works for Everyone

One of the biggest surprises about Windsurf is its pricing. It’s affordable, flexible, and well-suited to solo developers, startups, and enterprise teams alike.

Here’s a quick overview:

Compared to competitors like Cursor (which charges $20/month for fewer features), Windsurf undercuts the market while delivering more value. It even integrates directly with Netlify, enabling one-click deployments and cutting down on release times dramatically.

Enterprise-Grade Productivity

Windsurf isn’t just for solo developers. It’s been designed from the outset to serve entire engineering teams.

Real-Time Team Collaboration:
Multiple developers can work on the same project, at the same time, with the AI offering unified suggestions. This reduces merge conflicts, increases consistency, and enforces coding standards across the board.

Automation That Frees Up Mental Energy:
Windsurf can generate unit tests, write documentation, and create boilerplate code. These repetitive tasks become a thing of the past, letting developers focus on building the features that matter most.

Enterprise-Ready Security & Analytics:
Companies get access to security controls, permission layers, and powerful analytics dashboards that help engineering leaders understand code velocity, bottlenecks, and AI usage across teams. Windsurf addresses enterprise security concerns robustly. Data processing can be configured for local on-premise instances or within a secure, private cloud environment, ensuring code privacy. The platform is working towards SOC 2 compliance and employs industry-standard encryption protocols (e.g., AES-256 for data at rest, TLS for data in transit) to protect sensitive code and intellectual property. It also plays nicely with JetBrains and major CI/CD systems for seamless integration into your existing workflows.

Strategic Business Benefits

Here’s how Windsurf can transform your business:

• Faster Development Cycles: Cascade Write Mode can generate up to 90% of the code needed for a task, massively reducing build times.
