About this tool
Windsurf (formerly Codeium) is an AI-powered code editor and coding assistant that combines intelligent code completions with agentic workflows. Rebranded from Codeium in late 2024, Windsurf represents the evolution from AI autocomplete to an AI-native development environment.
The standout feature is Cascade, an agentic AI system that can understand multi-step instructions, make changes across files, run terminal commands, and iterate based on results — all while keeping the developer in control. Combined with Supercomplete (context-aware code completions) and inline chat, it covers the full spectrum of AI coding assistance.
Windsurf is built on a VS Code foundation, ensuring compatibility with the extension ecosystem developers already rely on. It offers both a standalone editor and extensions for existing IDEs including VS Code, JetBrains, and Neovim.
With competitive pricing starting at $15/month for the Pro tier — undercutting most competitors — and a generous free tier with 25 prompt credits, Windsurf positions itself as the most accessible entry point to agentic AI coding.
Key Highlights
Cascade Agentic AI
Multi-step AI agent that can plan, code, run commands, and iterate — handling complex tasks autonomously.
Supercomplete
Context-aware completions that understand not just your current file but your entire project and recent changes.
Multi-IDE Support
Available as a standalone editor and extensions for VS Code, JetBrains IDEs, Neovim, and more.
Zero Data Retention
Optional zero data retention on paid plans — your code is never stored or used for training.
Flow Actions
AI-powered workflows that combine code generation, terminal commands, and file operations in automated sequences.
Most Affordable Pro Tier
At $15/month, Windsurf Pro undercuts competitors while offering premium AI model access.
Use Cases
Agentic Feature Development
Describe a feature to Cascade and watch it plan the implementation, create files, write code, and run tests — intervening only when you want to steer direction.
Rapid Prototyping
Go from idea to working prototype faster with AI that handles boilerplate, API integrations, and file scaffolding while you focus on business logic.
Code Modernization
Use Cascade to migrate legacy code patterns, update dependencies, and refactor codebases with multi-file awareness and automated testing.
Learning and Exploration
The generous free tier with 25 prompt credits makes Windsurf an excellent starting point for developers exploring AI-assisted coding.
What Users Say
“Best value AI coding tool on the market”
At $15/month for Pro, Windsurf is half the price of Cursor and includes Cascade which is genuinely impressive for multi-step tasks. I've built entire API endpoints by describing what I want and letting Cascade handle the implementation. The rebrand from Codeium confused some people but the product has gotten significantly better.
