Definition
Windsurf is an AI-native code editor developed by Codeium, built around an agentic assistant called Cascade that can understand a codebase, plan multi-step changes, and execute edits and terminal commands with awareness of the developer's ongoing workflow.
Overview
Windsurf was launched by Codeium in 2024 as the company's evolution from a code-completion plugin (Codeium's original product, available as an extension for existing editors) into a full standalone IDE, similarly forked from VS Code's open-source base, positioning it as a direct competitor to Cursor in the emerging AI-native editor category. Codeium later rebranded its overall product line around the Windsurf name. The centerpiece of Windsurf is Cascade, an agentic assistant that goes beyond single-turn chat or inline edits by maintaining awareness of the developer's recent actions, terminal output, and codebase structure across a session, then using that context to plan and execute multi-step tasks with less need for the developer to manually specify every file or step. Windsurf popularized the term "flows" to describe this blend of copilot-style assistance (suggestions the developer reviews) and agent-style autonomy (the AI carrying out a sequence of actions on its own), aiming for an experience where the AI feels like a collaborator that stays synchronized with what the developer is doing rather than one that needs to be re-briefed at every step. Like Cursor, Windsurf indexes the local codebase for context-aware suggestions and chat, supports multiple underlying LLM providers, and offers autocomplete (Supercomplete), inline command-based editing, and chat. It differentiates itself partly through Codeium's original strength in fast, accurate autocomplete (built on Codeium's own retrieval and ranking infrastructure predating the IDE product) and through its emphasis on the assistant proactively tracking developer intent across a coding session rather than only responding to explicit prompts. Windsurf offers a free tier alongside paid plans with higher usage limits for Cascade and premium models, competing directly with Cursor and GitHub Copilot in pricing structure as the AI-native IDE market has grown increasingly crowded.

History
Windsurf is an AI-native, "agentic" integrated development environment built on the open-source core of Visual Studio Code. It was created by Codeium, a company that had launched in 2022 with a GitHub Copilot-style code-completion assistant delivered through editor plugins. Codeium announced the Windsurf Editor on November 13, 2024, positioning it as an "agentic IDE" and introducing "AI Flows" that combine the real-time collaboration of copilots with the independent capability of agents, giving the AI deep hooks into the whole development environment. The company subsequently rebranded fully from Codeium to Windsurf in April 2025, making Windsurf its flagship product.
