AI coding assistant (formerly Codeium) with autocomplete, chat, and Cascade agentic editing. Works as an extension in VS Code, JetBrains, and Vim. Free tier available.
Windsurf started as Codeium, a free AI code completion tool that undercut GitHub Copilot on price. It worked. Millions of developers signed up for unlimited free autocomplete. In late 2024, the company rebranded to Windsurf and shifted toward becoming a full AI IDE competitor, adding chat, an agentic editing system called Cascade, and a standalone editor.
The product's main draw is that it plugs into your existing IDE rather than replacing it. Install the extension in VS Code or JetBrains, and you get autocomplete suggestions, an in-editor chat panel, and Cascade for multi-file edits. Cascade is the differentiator: describe what you want in plain English, and it modifies files across your project. It works well for straightforward refactors and boilerplate generation. For complex architectural changes, it still needs babysitting.
