What is it

Windsurf is an AI-native Integrated Development Environment developed by Codeium, positioned as the first agentic IDE. It combines a local agent called Cascade that understands your entire codebase and performs multi-file edits, with a cloud agent called Devin that runs autonomously on its own machine. Together they handle everything from autocomplete to complex feature implementation, deployment, and testing.

What it can do

It can generate and edit code across multiple files simultaneously using natural language instructions, run terminal commands, deploy web apps directly from the IDE, convert image designs into working code, fix linter errors automatically, manage agent sessions through a Kanban dashboard, and connect to external tools via the Model Context Protocol. Tab autocomplete is unlimited and free on every plan.

Who is it for

Professional software engineers, full-stack developers, and engineering teams who want to move from writing individual functions to orchestrating AI agents that handle entire development workflows — from planning and coding to debugging and deployment.

Key Features

Cascade Agentic Coding – Local AI agent with full codebase awareness

Delegate complex development tasks to Cascade, an agent that maintains deep contextual awareness of your entire repository. It plans multi-step changes, reads relevant files, writes and edits code across multiple files, runs terminal commands, and handles errors autonomously — all while keeping you in the loop with checkpoints you can roll back at any step.

Devin Cloud Agent – Autonomous cloud agent on a dedicated machine

Hand off complex or time-consuming tasks to Devin, an autonomous cloud agent that spins up its own machine and works independently while you keep coding locally. Plan with Cascade, then delegate implementation, testing, or debugging to Devin with one click — perfect for tasks that need to run in parallel with your own work.

Agent Command Center – Kanban dashboard for all agent sessions

Manage every local Cascade session and cloud Devin session in a unified Kanban-style dashboard. Track what each agent is working on, monitor progress, and switch between tasks without losing context — turning scattered AI interactions into an organized workflow.

Spaces – Bundle agents, PRs, and files around single tasks

Group related agent sessions, pull requests, files, and shared context into Spaces so you never lose your place. Each Space becomes a persistent workspace for a specific feature or bug fix, keeping all relevant history and artifacts in one organized location.

Use Cases

Full-stack feature development

Developers describe a new feature in natural language, and Cascade plans the implementation across frontend components, API endpoints, database migrations, and tests — then executes the changes across all relevant files while the developer reviews and refines.

Multi-file refactoring at scale

Engineering teams use Cascade to refactor large codebases by describing the architectural change in plain language. The agent identifies all affected files, updates imports, renames symbols, and adjusts types across the entire project — work that would take hours manually is completed in minutes.

Autonomous debugging and testing

Developers delegate complex debugging sessions to Devin, which autonomously analyzes error logs, traces stack traces, writes reproduction tests, and implements fixes on its own machine. The developer reviews the completed PR when Devin finishes — turning debugging from an interrupt into a background task.

Rapid prototyping with live previews

Product teams and indie hackers drop a design image into Cascade, get working UI code generated instantly, preview it live in the IDE, iterate through chat refinements, and deploy to a public URL — going from idea to deployed prototype in a single session without leaving the editor.
